KANSAS CITY, MISSOURI

EXCITING PROGRAM PLANNED FOR ONSITE AND VIRTUAL ATTENDEES! On behalf of the National Meeting Program Committee (NMPC), I would like to welcome you to Kansas City, Missouri, for our 72nd AALAS National Meeting. We have put together a stimulating and exciting program that we hope you can enjoy and benefit from, whether you made the trip to Kansas City or are attending virtually. As we are just emerging from our pandemic bubbles, this meeting presents a great opportunity to learn from and reconnect with our colleagues. I would like to thank the NMPC, and the Local Arrangements Committee for their time and effort during a difficult year, in putting together a terrific program. I would also like to extend a huge thank you to the AALAS staff for showing tremendous flexibility and innovation in enabling virtual content for this conference but also rolling out the “Ask Me Anything” sessions and vendor “Demo Days” this past year. Finally, a well-deserved thank you to those that submitted topic ideas and abstracts. We had so many great submissions this year. This is a testament to the resolve and commitment of the members of our community to share knowledge and research during a very difficult year. Please enjoy the meeting content that this group has worked hard to put together for you!

Rachel Rubino, DVM 2021 Program Committee Chair

IT IS TIME TO GATHER AGAIN! Dear AALAS Nation, It is with indescribable joy that I welcome you to the 72nd Annual AALAS National Meeting in Kansas City! As you all know, we could not hold the 2020 AALAS National Meeting in person for obvious reasons. Although the virtual meeting was a success, we must admit it was not anything like coming together. So, this year, as we prepare to meet IN PERSON IN KANSAS CITY, one thing occurs to me; that we are meeting is perhaps more important than the meeting itself. Trust me when I say that Dr. Rachel Rubino and her program committee have assembled a stellar program, a product of the excellent content submitted by our membership. You will want to soak in all you can. But, this year, more than any other in recent memory, we need to be together. The long-awaited time to gather with your friends and colleagues once again has come.

Doug Taylor, DVM 2021 AALAS President

“I’m going to Kansas City, Kansas City, here I come!” The spirit expressed in this classic rock ’n roll song pretty much speaks for all of us who are planning the trip this year to the 72nd AALAS National Meeting. As the Chair of the Exhibitor Advisory Council and from all of us at AALAS, we are glad to extend a warm welcome. Without any further discussion about the challenging business and social climates we’ve all experienced over the past many months, we look ahead with excitement to our in-person annual meeting, the largest gathering of professionals concerned with the use of laboratory animals and commercial partners that support the lab animal science community. As in years past, thanks go to those who work behind the scenes of this important gathering who have been busy throughout the interim making sure this year’s meeting reflects the best of those of us who will meet to teach, learn and share our expertise and experiences with the lab animal community. Attendees will be encouraged to take full advantage of the event by attending the many informative talks and presentations curated by the respective AALAS councils, view the hundreds of posters, and by joining the workshops led by the leading professionals in their fields. Check these pages to plan your schedule. In our role to serve both commercial and professional partners, AALAS is once again proud to present two tracks of Technical Trade Presentations on Sunday, October 17: “Innovative Solutions in Animal Welfare” and “Is Your Facility State-ofthe-Art” This valuable forum is where exhibitor members will highlight products and services that provide innovations and benefits to the workplace environments and challenges regularly faced by new and veteran attendees. Be sure to review the topics covered and make your plans early to attend these informative presentations. Especially this year, many attendees are looking forward to visiting their friends, colleagues, and suppliers to learn about new products and solutions. For two and a half days, the exhibit hall at Kansas City will the ideal venue for this important networking and is sure to have something for all. There are a number of new exhibitors joining for the first time in addition to the mainstay commercial partners we have come to rely on to exhibit their latest advancements under one roof. You won’t want to miss the Ribbon Cutting Ceremony at 8:30 a.m. in the main exhibit hall. On behalf of the EAC Council, AALAS, and all of our 1,300 plus commercial members of the lab animal science community, welcome to Kansas City and the 72nd AALAS National Meeting! “Kansas City, here we come!”

TECHNICAL TRADE PRESENTATIONS TRACK I – INNOVATIVE SOLUTIONS IN ANIMAL WELFARE Feed Safety in the 21st Century: An Overview of Feed Safety Programs Used in Laboratory Animal Feed Production 1:00 PM - 1:20 PM/ Room: 2505A Speaker/Moderator: Laura N Tracey

Safe manufacturing practices are of the utmost importance to laboratory animal feed manufacturers, from choosing and receiving ingredients to packaging finished products and preparing for shipment to facilities. This talk will briefly summarize the different programs followed to ensure only the highest quality of feed is provided. It will include information about corporate guided systems as well as scrutinous external, third-party certification programs implemented. Of particular focus will be Food Safety System Certification 22000 (FSSC 22000), an elite third-party certification held by a select few feed manufacturers globally. Information provided will inform attendees, including facility managers, veterinarians, and researchers, of important feed safety measures they should expect from their feed manufacturing company to ensure their most important assets, the animals and research, are never compromised. This Technical Trade Presentation is sponsored in part by PMI Nutrition International (LabDiet).

Solutions to Improve Animal Study Reproducibility 1:20 PM - 1:40 PM/ Room: 2505A Speaker: Brad Nemer Moderator: Nathan Fahrenthold

A 2012 study published by Amgen researchers found that 90% of the in vivo oncology studies were not reproducible. Historically, 95% of post-phase III oncology clinical trial therapies failed to receive regulatory approval due to a lack of demonstrated efficacy, not toxicity. The lack of reproducible data underscores the need to examine current animal study conduct processes for potential improvement areas. In today’s competitive climate, researchers must identify poor animal study reproducibility causes and implement meaningful and effective solutions. Recently, questions and debates concerning the validity of preclinical science data have resulted in multiple published reviews. Cost-effective technology exists to mitigate this crisis of animal study irreproducibility. Studylog’s presentation covers the factors contributing to poor animal study reproducibility and publicly available and online resources and practically applicable concepts, such as the ARRIVE guidelines, PHISPS protocols, and the N3R Design Assistant. Attendees receive first-hand experiences with various animal study conduct approaches and commercially available animal study workflow software applications, along with a summary of each tool’s direct and indirect impacts on the causes of animal study irreproducibility. Attendees will explore the Studylog Animal Study Workflow Software in the context of solving problems, improving animal study reproducibility, and faithfully preserving detailed study results for future access. Researchers will leave the presentation with an understanding of the factors contributing to animal study reproducibility failures and the application of the latest public, online tools to mitigate reproducibility issues. Scientists attending this presentation will experience what animal study workflow software is like and how it can help solve many

study reproducibility concerns while easily standardizing processes of detailed study design planning and study conduct. This Technical Trade Presentation is sponsored in part by Studylog Systems, Inc.

A Novel System for Continuous, Undisturbed, and Remote Monitoring of Digital Biomarkers Temperature and Activity - in Group-housed Mice 1:40 PM - 2:00 PM/ Room: 2505A Speaker: Jose Gadea Moderator: Matthew Ruiter

Animal temperature, activity, and behavior are essential parameters to assess in biomedical research when evaluating the efficacy of pharmacological agents and for monitoring animal welfare. Current systems designed for evaluating activity and behavior in mice usually involve removing the animals from their home-cage and placing them into novel environments. Here they undergo a series of tests, which are often conducted for short periods of time, under social isolation and during their sleep phase. Furthermore, common methods for recording animal temperature require the use of intrusive devices (i.e., rectal probes) that require frequent animal handling, which also alter animal behavior. These methodologies often introduce unwanted levels of animal stress, which can interfere with study outcomes. Therefore, there is a need for a system that allows for automated monitoring of individual mice housed within their social environment to remove researcher bias and animal disruption during experimentation. The UID Mouse Matrix was developed to address the chal-

lenges researchers currently face when evaluating temperature and activity in socially housed and undisturbed mice. This presentation will describe a novel RFID-enabled system that allows continuous and remote monitoring of digital biomarkers, such as locomotor activity and temperature, for one or multiple mice in their home-cage environment. Participants will learn how this system can be used to automatically monitor key digital biomarkers from group-housed mice and collect data in real-time (24/7), even in the dark phase when animals are most active, and evaluation would not be feasible with current methods. In addition to removing experimenter bias, the system has the potential to improve study outcomes by enabling frequent and accurate measurement of progressive behavioral and physiological changes in the same animal. The target audience includes research directors, lab facility managers, animal care program directors and supervisors, veterinarians, IACUC members, research personnel, and lab animal technicians. This Technical Trade Presentation is sponsored in part by UID Identification Solutions.

acceptance of this technology is due to several factors, including improved animal welfare, prolonged catheter patency, and ease of use for researchers. However, there are some limitations to the technology, such as restrictions to the study design due to a dependence on liquid swivels, and the fact that incorporating buttons into the protocol still requires humans to be present to collect samples. A commercially available automated sampling system that addresses these issues already exists. By combining the two technologies, it is possible to create a flexible study that takes advantage of both the buttons/ports and the low-stress sampling system. In this system, movement responsive caging takes the place of a liquid swivel. The animal tether can be easily changed to accommodate the button, a collar, or a harness all while increasing the number of fluid lines that can be connected. In addition, the system makes it possible to collect programmed blood samples anytime of the day or night. This means that researchers do not have to handle the animal or even be present during the collection periods, resulting in increased laboratory efficiency, better study data from low-stress animals, and the ability to run studies while staying socially distanced. Recent updates to the automated sampling system make it easier than ever to integrate with the port and button technology.

New Developments in Percutaneous Catheter Access Buttons for Small and Large Animal Research 2:20 PM - 2:40 PM/ Room: 2505A Speaker: Merryl Cramer Moderator: Kelly Gregrow

In recent years, buttons have become a preferred method to access catheters for infusion and sampling in rodents. Buttons consist of a rigid housing protecting the externalization site of the catheter anchored by a fiber ingrowth disk. Access is gained by piercing a self-sealing silicone septum minimizing animal interference while creating clean, easy access to the intended site. The use of buttons with protective metal caps in rats and mice has improved animal welfare by permitting group housing and, in many cases, has extended catheter

patency. In large animal models, the more common approach is to use a Vascular Access Port (VAP) or an externalized catheter. The externalized catheter can be difficult to keep protected and clean, especially for long-term studies. VAPs require the use of a non-coring needle to pierce the skin at each access. Using a needle increases the risk of needle-stick incidents and can increase the likelihood that the animal will become sensitized or “needle-shy.” New catheter access button technology makes it possible to easily access the catheter without the risk of catheter disconnects or needle-stick accidents. New technology has been developed using this platform, improving animal welfare while making studies safer for both animals and researchers alike. In this presentation, we will share the updated technology, discuss the benefits and limitations of using this updated technology in both large and small animals, and share details on integrating these new products into a variety of research protocols. This session will be most beneficial for researchers performing awake animal studies, which require dosing and sampling, focusing on large animal species. The data will also be relevant to any animal researchers who are struggling with catheter patency issues. This Technical Trade Presentation is sponsored in part by SAI Infusion Technologies.

Working With Isoflurane Anesthesia: Is It Safe for Me and My Animals? 3:00 PM - 3:20 PM/ Room: 2505A Speaker: Eugene Marino Moderator: Perry L Spires

Isoflurane was developed as a safer alternative to the use of flammable ethers for anesthesia in the early days of surgery and was approved for medical use in the United States in 1979. Since then, it has become the ubiquitous agent for inhalant anesthesia in veterinary and laboratory research surgeries. But what about the safety of isoflurane not just for the animal subjects, but those who work around it on a regular basis and experience waste anesthesia gas exposure? What are the hazards and short and long-term effects to both personnel and animals from exposure? A quick look at available data and even the lab animal resource protocols of research centers show there is not even a consistent description of its isoflurane, much less empirical evidence of its risks. While we do have recommended maximum exposure limits from NIOSH, what exactly do, and don’t we know about safely working in an environment where isoflurane is in regular use? Our talk will outline what known and suspected risks are faced, what measures we can take to protect ourselves, and what methods and equipment are appropriate and safest to use. This presentation will be of interest to all laboratory and animal welfare personnel who perform surgeries or do other research work that requires the use of isoflurane anesthesia.

The Value of Documenting Your Animal Care and Husbandry Data with an Integrated Management Software 3:20 PM - 3:40 PM/ Room: 2505A Speaker: Eric Y Rieux Moderator: Mathew D Sanderson

When is the last time cages were changed? When is room ABC123 due for cleaning? How many cases of diarrhea has this NHP had in the last 2 years? Did we change diets on those dogs last week? How many matings did we start this week? How many mice are remaining on Dr. Jane’s protocol? How many males weighing between 2.8Kg and 3.3Kg and have not been in a study for 2 weeks are available right now? Are my rats recovering well from the surgical preparation? Where was that group of animals housed, and with which other animals were they in contact? Why did my control group unexpectedly react, was anything else going on in the vivarium? How many questions of this type do you get or ask yourself? How quickly can you answer so the best-informed decisions are made? This presentation will focus on the value and power of seemingly simple vivarium data that can easily be collected, stored, and mined as lab animal technicians go about their daily tasks. In this presentation, you will learn how collecting data while being animal-side is getting ever easier thanks to automation and connectivity of devices and software; how reporting and extracting meaningful data lead to increased animal welfare, better science, and more effective management decisions. The target audience for this presentation includes technicians, veterinary care staff, facility managers, and researchers.

overlooked or accepted as normal. However, it is indicative of reduced wellbeing and is an underestimated welfare issue in laboratory mouse breeding. Successful breeding is a critical part of providing animals for research, and cannibalism should be considered a serious problem in the lab animal vivarium. Indeed, reduced breeding performance leads to increased costs due to increased technician time and cage numbers. Cannibalism and pup mortality can even cause the complete loss of precious transgenic lines. This inefficient production violates the principles of the 3Rs, which define the refinement of research to enhance the welfare of animals and improve the quality of science. In this presentation, directed towards animal caretakers, students, postdocs, investigators, and veterinarians of all levels, we will review the causes and consequences of cannibalism and pup mortality and outline environmental and nutritional solutions to maximize the breeding performance of your rodent colonies. Our presenter has over 10 years of experience working with mice during her PhD and Post-doc. She coordinated contract mouse breeding services for researchers as a Breeding Project Manager at The Jackson Laboratory and is the author of many blog articles on breeding support.

Designing a UV-C Disinfection Pass-through

1:40 PM - 2:00 PM/ Room: 2503A Speaker: Emily Lorcheim Moderator: Kevin Lorcheim

This presentation is designed to discuss how laboratories can easily transform a space into a disinfection room. This capability allows for the transfer of items from a non-clean room setting and into a clean-room, disinfect incoming pallets, equipment, supplies, feed, and bedding bags, or simply disinfect communal spaces after use. Topics discussed will include the science and technology of ultraviolet light disinfection, pros, and cons to the method of disinfection, and applications. Details will include how to determine the necessary quantity, type, and placement of UV-C devices and options for installation and safety measures. The addition of a UV-C disinfection devices mounted on walls or ceilings can reduce organism colony counts significantly in a laboratory setting due to the elimination of human error and the overall effectiveness of the technology in a well-designed setting. The benefit of creating a disinfection room with the sole purpose of disinfecting incoming or used items is that possible external contaminants can be eliminated before entering a facility or even a different section of a facility. The application is easy to implement, is not a high capital expenditure, and creates a disinfection method that is very efficient in terms of both time and efficacy.

WORKSHOPS W-01 A Guide to Implementing Evidenced-based Medicine in Laboratory Animal Medicine 8:00 AM - 12:00 PM/ Room: 2202 Leaders/Faculty: Zachary T Freeman, Portia S Allen, Joseph A Hampel Facilitator: Pradeep K Dumpala Workshop Fee: $150 Workshop Limit: 50

Laboratory animal medicine programs are faced with an ever increasing need to use evidenced-based decision making to guide everyday practices and clinical medicine. Evidenced-based medicine relies on a scientific approach to answer questions of interest with a particular emphasis on historical and generated data. Electronic capture systems that record data, such as census and medical record systems, are becoming more common in LAM and have increased the amount of data. Using these increasingly large datasets, often called big data, to guide decision making present significant challenges in understanding how to best answer programmatic questions. In this workshop, we will discuss best practices of approaching and using big data in laboratory animal medicine to guide both clinical and programmatic decisions. We will address how many of the challenges associated with big data including data collection and management, question generation, and analysis impact the decision process. We will combine literature review, lectures, and group-based discussion of real-world big data in LAM cases to discuss approaches to address these challenges. The aim of this workshop is to facilitate guided discussion and expose participants to practical ways to integrate evidenced based medicine in LAM programs. This workshop is intended for those involved in programmatic leadership and clinical medicine with interest in using evidenced based medicine in the overall decision-making process.

W-02A Microsurgery Skills Training Using Surgical Loupes 8:00 AM - 12:00 PM/ Room: 2201 Leader: Robert F Hoyt Jr Faculty: Robert F Hoyt Jr, Tanya L Herzog Facilitator: Margaret A Hull Workshop Fee: $250 Workshop Limit: 20

Performing surgical procedures with the aid of magnification has gained widespread use in human medicine over the past 30 years. Using surgical loupes, surgeons can now perform procedures on very small structures that were considered impossible a few decades ago. Within the past 25 years, the use of magnification to perform microsurgical techniques has also quickly spread to other health care disciplines, including dental specialties and dermatology, to increase surgical precision, such that it is now considered the standard of care to use them. The use of microsurgery and its value to biomedical research has, unfortunately, only just begun to be realized. Because of their small body structures, laboratory animals such as rats and mice, have generally not been considered as animal models for many types of surgical procedures routinely performed in biomedical research. Investigators have rather elected to utilize larger species such as dogs, pigs, sheep, rabbits, or nonhuman primates for such modeling because both surgical support equipment is more readily available, and the surgical techniques are more familiar to the support personnel. The recent shift to using genetically engineered rodents, especially mice, has now resulted in increased researcher desires to utilize these animals in more sophisticated modeling procedures, especially surgery. Rather than being limited to only simple procedures such as IM, IP, or IV injections, researchers using microsurgery can now perform complex surgical procedures on many rodent organ systems, such as the heart, lungs, and the gastrointestinal tract. This workshop will

introduce the basic techniques, equipment, and general applications of microsurgery using surgical loupes. Hands-on training will be conducted in 2 phases: teaching students to develop technical skills by performing exercises using surgical loupes and applying these skills to perform simple surgical procedures using rodent and organ surrogates. The target audience are Veterinarians, Technicians and Investigators interested in gaining skills in microsurgery using surgical loupes.

SEMINARS Mammals and Microbial Communities: What We've Learned from Animal Models 8:00 AM - 10:15 AM/ Room: 2501B Leaders: Robert P Marini, Richard J Hurley Moderator: Richard J Hurley Facilitator: Lisa A Quinn

This seminar pays tribute to Dr. James G. Fox on his retirement after more than 45 years dedicated to comparative medicine by focusing on animal models used in microbial and microbiome research led by Dr. Fox and/or his trainees. Presentations are designed for scientists using animal models to study the microbiome and/or infectious diseases and for clinical laboratory animal veterinarians responsible for maintaining healthy research animals. The session opens with a historical review of animal models in infectious disease research. When the natural gastric microflora was “rediscovered” in the early 90s, several animal models became important in determining the contribution of these organisms to gastritis, ulcer disease, and cancer in both man and animals. Many of the early studies were performed by investigators in the Division of Comparative Medicine at MIT, working in conjunction with an international team of collaborators. This session will cover the history of those studies and their contributions to the early understanding of helicobacter-induced disease. The audience will then learn how investigations of natural infections and diseases in laboratory animals lead to experimental animal model generation guiding our understanding of disease pathogenesis and providing a window into the microbiome. The final presentations introduce how animal models inform research on the importance of the microbiome in human health and disease. The audience will learn how the gastrointestinal tract microbiota stimulates tissue specific host immune and neuroendocrine responses in multidirectional gut-brain-immune axes that contribute to sustained good health, and how the tractable nature and wide array of genetic engineering opportunities make the microbiome an attractive target for diverse biomedical applications to improve human health. Finally, the audience will learn how much of the research into the human microbiome has been guided by using animal models, and the challenges involved in using animal models due not only to differences in the host anatomy and physiology but also differences in the “anatomy” and physiology of the indigenous microbiota.

Switching to Environmental Health Monitoring for Rodents: How, Why, and Will It Cost More? 8:00 AM - 10:15 AM Leader/Moderator: Megan R LaFollette Facilitator: Theresa M Cunningham

It is important to ensure that rodent colonies are free of adventitious infectious agents to support high-quality, robust research and safety data. Over the last 50 years, health surveillance has been typically performed using sentinel animals. More recently, molecular-based diagnostics combined with environmental monitoring strategies have been adopted by many institutions to either supplement or replace the more traditional methods. These newer approaches have the possibility of significantly reducing/replacing the number of rodents used in maintaining specific-pathogen-free colonies. However, switching can be difficult. In this seminar, participants will learn how and why several large institutions have made the switch, cost efficiencies of switching, a method to use PCR testing with in-cage filter paper, and common misconceptions. The target audience for this presentation is veterinarians and vivarium managers that are familiar with rodent health monitoring programs.

AquaFeed Z ®

Gel Technology: Addressing Zebrafish Husbandry Challenges The First Gel Diet Specifically Formulated for Zebrafish With the increasing popularity of zebrafish as a research model, there is corresponding focus on optimizing husbandry practices to address the current challenges of inefficient feed delivery, waste management, and standardized nutrition. Diet, and its form, is a key component to solving these challenges. ClearH2O, well-known by the research laboratory animal community as leaders in product innovation for hydration, nutrition, and medication delivery gel supplements and diets for terrestrial lab animals, has applied their proprietary technology to developing the first aquatic gel diet specifically formulated for zebrafish, AquaFeed® Z. AquaFeed®Z represents the introduction of ClearH2O’s gel delivery platform incorporating a diet formula based on the most up-to-date knowledge of the specific nutritional requirements for zebrafish integrated into a sustained delivery gel cube. The physical properties of the AquaFeed®Z gel cube elicits a more natural grazing behavior in contrast to the frantic, binge feeding associated with dry flake or pelleted diets. AquaFeed®Z improves fish health and welfare by supporting uniform feeding by all fish, reducing competition and stress. Truly unique to the gel product format of AquaFeed® Z, is the physical property of being cut into a clean, consistent unit of measure; 1 cube = 1 gram. Feeding guidelines indicate the dosage of 1 gram per 10 adult zebrafish, making this unit of measure convenient for technicians to easily scale up or down depending on fish tank density. In addition, in contrast to dry diets, handling of the gel cube allows for clean application outside and inside the fish tank.

AquaFeed® Z is ready-to-use, room temperature shelfstable, and packaged in 190 gram pouches. 30 pouches per case.

AquaFeed® Cutting Device produces uniform 1 gram cubes for clean consistent dose administration.

The Clearly Better Diet Solution for Zebrafish Husbandry Nutrient Specific – Formulation based on nutrient requirements that researchers have identified as specific for zebrafish growth, reproduction, and maintenance. Quality Ingredients - Made with purified ingredients, including sustainable protein with high digestibility for optimum nutrient utilization. No fillers, added starches, or binders.

Natural Feeding – Gel cube properties provide for a longer feeding period and more natural grazing behavior, reducing stress and competition for food, resulting in improved fish welfare. Consistent Unit of Measure – Designed to be cut into uniform 1 gram cubes for ease of clean and consistent feed administration. Each cube of AquaFeed® Z is 1 gram. The firm gel properties allow for clean and consistent administration.

SPECIAL TOPIC LECTURES 2021 Update Regarding Changes at ILAR

11:00 AM - 12:00 PM/ Room: 3501A Speaker: Robert C Dysko Moderator: Teresa J Sylvina Facilitator: Darlene Royce

The Institute for Laboratory Animal Resources (ILAR) has been a unit within the National Academies of Science, Engineering, and Medicine (NASEM) for the past 68 years. During this time, it has published a journal and multiple national guidance documents regarding animal use in research, and most notably has overseen the process for creating and revising the Guide for the Care and Use of Laboratory Animals. Recently, NASEM invited ILAR to assume wider programmatic responsibilities concerning animal research, specifically noting wildlife conservation and One Health initiatives. Membership on the ILAR Council has reflected this change, but additional efforts are forthcoming. The speaker will highlight recent and proposed changes at ILAR, including a workshop on IACUC review of wildlife field studies and similar non-model research, a new process for revising the Guide, and a new name for the institute. A question-and-answer session will follow with Dr. Dysko and Dr. Teresa Sylvina, ILAR director. The target audiences is laboratory animal scientists and veterinarians, IACUC members and administrators, and any individuals interested in science and research that involves animals.

Charles C Hunter Lecture: Aerobic Capacity, Energy Metabolism, and Risk for Metabolic Disease 11:00 AM - 12:00 PM/ Room: 2501B Speaker: John P Thyfault Moderator: Lindsay N Zinser Facilitator: Daniela A Miller

This lecture will focus on the role of aerobic capacity linked changes in energy metabolism and their effect on susceptibility for fatty liver and obesity. The speaker will also show how thermoneutral housing alters energy metabolism dramatically in rodents and thus influences their susceptibility for diet induced obesity and metabolic dysfunction. This Special Topic Lecture is sponsored in part by Committee for Technician Awareness and Development (CTAD).

From Rabbits to Rodents: Current and Practical Analgesic Techniques for Laboratory Animals 11:00 AM - 12:00 PM/ Room: 2501A Speaker: Rebecca A Johnson Moderator: Kathy Laber Facilitator: Carolyn M Doerning

This lecture, presented by a research anesthesiologist and diplomate in the American College of Veterinary Anesthesia and Analgesia, will focus on the newest, yet most practical analgesic techniques used in laboratory animal species. It will emphasize novel pain scoring systems, advances in clinical analgesic techniques, and the most useful analgesic agents and procedures for laboratory animals, including alternatives to classic, parenteral opioid analgesics. Information gained will be valuable for all laboratory animal caretakers, including principal investigators, laboratory members, animal care staff, veterinary technicians, and veterinarians. This seminar comes at a time when the prompt and accurate diagnosis and treatment of laboratory animal pain is becoming more overarching in the research setting with the paramount goal of improving animal welfare and well-being, but also aiming to minimize the effects of unaddressed pain on research investigation outcomes. Attendees will come away with a deeper understanding of how to properly recognize and treat acute and chronic pain states in various laboratory animals using the most up-to-date clinically available analgesic techniques.

History of Animal Research in Pandemic Responses 11:00 AM - 12:00 PM/ Room: 2501C Speaker: Jacqueline K Brockhurst Moderator: Jason S Villano Facilitator: Natalie Castell

The incredible response from the global scientific community during the COVID-19 pandemic, exemplified by the development of multiple SARVS-CoV-2 vaccines in under a year, was made possible in part because of animal research. Historically, animal models have been used in the characterization, treatment, and prevention of most of the major infectious disease outbreaks that humans have faced. From the advent of modern germ theory prior to the 1918 Spanish Flu pandemic through more recent Ebola and Zika virus outbreaks, research in animals has supported key discoveries in disease pathogenesis and therapy development, helping to save lives in a crisis.

PANEL DISCUSSIONS Animal Research: Time to Talk!

12:30 PM - 2:00 PM/ Room: 3501G Leaders: Kirk Leech, Javier Guillén Moderator: Kirk Leech Facilitator: Eva C Maciejewski Panelist: Javier Guillén, Ana I Santos, Serban Morosan, Ana Barros, Liesbeth Aerts

Openness in the public debate on animal research has been increasing in many European countries and research institutions. Since the 2014 launch of the UK Concordat on Openness on Animal Research, the scientific community in Spain, Portugal, Belgium, and now France have combined in national transparency agreements and have agreed commitments that seek to improve transparency with the public. Through these commitments, institutions pledge to take a proactive approach in explaining when, how, and why they use animals in research. They agree to provide information to the public and the media about the conditions under which animal research is carried out and to explain the results obtained from such research. They pledge

to develop initiatives that generate greater public knowledge and understanding about the use of animals in scientific research. They also commit to reporting on progress annually so that the impact of these transparency agreements can be measured. All signatories should also have a recognizable position statement on their institution’s website, describing their policy on the use of animals. In this panel discussion representatives from the countries that have national transparency agreements will explain what the drivers were towards this openness approach; they will provide a toolkit for those attending on how these agreements can be created and maintained; reveal how openness and transparency is a less reputationally risky approach to defending the use of animal models; and reveal the positive impact this approach has had on researchers, institutions, and the public. The discussion is designed to support all those involved in the use and treatment of laboratory animals, that wish to be more open about the animal research they conduct. The focal theme is to discuss how and why scientists, researchers, press officers, and other stakeholders should talk about animal research.

gesia being the most common adjunct providing balanced anesthesia, pre-emptive/multimodal analgesia, or by itself as postoperative analgesia. There is always an art and science involving mouse anesthesia. Anesthesia plan should be designed from the beginning to the end, and after procedures. While a frequently used anesthetic protocol may work perfectly for each mouse anesthetized, sometimes unexpected complications arise and quick adjustments to anesthetic depth and patient support are required. The purpose of this panel discussions is to deliberate the science of mouse anesthesia together with the art of applying these anesthetic techniques to provide audiences with the knowledge needed for successful anesthetic procedures. The authors include experiences in mouse inhalant and injectable anesthesia, peri-anesthetic monitoring, specific procedures, and analgesia. Attendees are encouraged to bring their questions regarding mouse anesthesia and analgesia. This Panel Discussion is sponsored in part by Fidelis Pharmaceuticals.

Pilot Survey Results on Diversity and Inclusion within AALAS 12:30 PM - 2:00 PM/ Room: 2504A Leader/Moderator: Temeri Wilder-Kofie Facilitator: Jessica T Hunt Panelist: Janet L Steele, James D Macy, James R Champion, Temeri Wilder-Kofie, Luis M Zorrilla, Chandra D Williams, Mark A Suckow, Sonja T Chou

In light of the 2020 events and the ongoing issues this country is experiencing regarding inequalities and race, AALAS formed the Diversity and Inclusion Ad Hoc Committee to develop a D&I mission statement for the organization. But is developing a mission statement enough? To help answer this question, the D&I Ad Hoc Committee launched a pilot survey to gather information on the perception of diversity and inclusion within AALAS to gather views, opinions, and suggestions from the members on this topic. The survey results will determine how the committee will proceed. We will discuss the D&I mission statement and pilot survey results and have an open discussion on what may come next regarding D&I within the AALAS. Participants will understand what diversity and inclusion mean to AALAS

members; to foster a discussion of views and perceptions of diversity and inclusion with regards to AALAS; and identify gaps and action actions that may be needed to progress and learn from our shared experiences regarding current societal issues. The target audience is all national and branch AALAS members and stakeholders. This Panel Discussion is sponsored in part by American Association of Laboratory Animal Science (AALAS) D&I Ad Hoc Committee.

The Veterinary Consortium for Research Animal Care and Welfare and Stakeholders Discuss Progress and Areas of Interest for the Guide Revision

This panel discussion introduces the Veterinary Consortium for Research Animal Care and Welfare (VCRACW), which is composed of representative veterinarians from ACLAM, ASLAP, APV, and AALAS. The goal of the VCRACW is to provide information on the care and use of research animals to inform the public, lawmakers, and the scientific community about the veterinary care and welfare of these animals. The current Guide for the Care and Use of Laboratory Animals was last revised in 2011. The Consortium has been following the current discussion of the development of a new Guide which could be very different from previous versions and has a proposed a five-step process. Each representative organization is a major stakeholder in this final product. This discussion will focus on issues of concern to the organizations involved in the VCRACW with an emphasis on the need for transparency in the process and the need for the use of relevant scientific data in revising the existing document. The intended audience is all who are involved with the management of an animal care and use programs. This Panel Discussion is sponsored in part by American College of Laboratory Animal Medicine (ACLAM), American Society of Laboratory Animal Practitioners (ASLAP), American Association of Laboratory Animal Science (AALAS), Association of Primate Veterinarians (APV), and Ad Hoc Consortium Representative.

The NIH’s Final Report on Recommendations to Reduce Administrative Burden on Researchers (released 8/28/2019) contained actions proposed by the working group from the NIH, USDA, and FDA to reduce administrative burden on investigators while maintaining the integrity and credibility of research findings and protection of research animals. Since its release, both the NIH and the USDA have solicited input on proposed changes to their oversight process. In

A A LAS 7 2 ND NATIO NAL MEETI N G


addition, the USDA has made some changes to the inspection process and the information contained in the accessible database. Also, the restrictions implemented to address the COVID-19 pandemic have impacted how both animal care and use programs and the oversight processes operate. All of this either has had or will have an impact on how animal care and use programs are managed going forward. This seminar will provide the attendees with an opportunity to hear from representatives of the USDA, OLAW, AAALAC International, the DOD, and NABR regarding possible changes, as well as other ongoing issues, within their organizations and to discuss with those representatives how their organizations’ activities impact the environment in which we work and what changes to expect in the future. Questions for the panelists can be submitted to btbdvm@yahoo.com. The target audience will be those who need to keep current with the regulations and requirements for conducting animal based biomedical research.

You may feel proficient, even confident in performing rodent surgery; however you may be surprised how small improvements can have a huge impact to your animal’s recovery and data. During this workshop, participants will learn and refine commonly used suture, knot-tying and rodent surgical draping techniques. The workshop will focus on appropriate hand-eye coordination to improve suturing skills and provide updates from recent scientific studies on the benefits of using Press’n Seal® and Reynold Wrap® aluminum foil wrap in routine rodent surgical aseptic procedures. A state-of-the-art inanimate model will be introduced and utilized during the suture practice. Easy to apply hands-on exercises will be put into practice that have been shown to significantly improve aseptic technique with Press’n Seal® and Reynold Wrap®. This workshop is designed for individuals who have minimal or no suturing skills but is also a great opportunity for those with considerable experience wanting to upgrade their skills and teach others enhanced technique. It is also for those that wish to improve and teach rodent surgery aseptic technique with quite simple to implement methods. This Workshop is sponsored in part by Kent Scientific Corporation, SurgiReal Products, Inc and Atramat.

SEMINARS ASAP: Assessment and Surveillance of Adverse Phenotypes in Genetically Engineered Models (GEMs) 8:00 AM - 10:15 AM/ Room: 2501B Leader/Moderator: Jeffrey J Lohmiller Facilitator: Megan M MacBride

Generation of genetically engineered models (GEMs) is associated with animal welfare challenges due to the adverse phenotypes that may manifest because of the genetic modification, a change in genetic background, or a change in health status or microbiome. Depending on the phenotype, special husbandry or observations may be required and humane endpoints developed. The Guide for the Care and Use of Laboratory Animals states “determination of humane endpoints should involve the PI, the veterinarian, and the IACUC, and should be defined when possible before the start of the study.” To meet and exceed regulatory and industry standards, we sought to develop and implement a process to evaluate novel and established models for adverse phenotypes, including a communication plan to animal care staff on clinical observations and humane endpoints. Our speakers will discuss how we were able to assemble a collaborative problem-solving method (using the Sprint method developed by Google) to quickly develop the best solution to our GEMs welfare concerns.

A A LAS 7 2 ND NATIO NAL MEETI N G


We will discuss our innovative questionnaire that requests details from researchers and allows us to categorize the line by organ system, plus examples of our global severity scoring system and assessments for models, as well how we conduct postapproval monitoring for such lines. At the end of the seminar, we welcome discussion and ideas from the audience on other ways to predict adverse phenotypes and communicate them to the staff and IACUC. This presentation should be of interest to veterinarians in clinical and regulatory roles, researchers working with GEMs, as well as animal care staff that work with GEMs and IACUC members.

Cultivating a Culture of Employee Recognition

8:00 AM - 10:15 AM/ Room: 2501C Leader: Denise M Molk Moderator: Gerald M Cronin Facilitator: Katherine L Head

Employee recognition is a cornerstone to successful management. Successful recognition is as varied as the employees you wish to recognize; the same form of recognition can be received in vastly different ways by different individuals. Yet, when effective, employee recognition can improve employee morale, attract, and retain employees, and elevate productivity. The Center for Comparative Medicine at Massachusetts General Hospital (MGH) has developed an employee recognition program and committee termed the Committee for Awareness, Recognition and Education (C.A.R.E team). This is an employee-led group that sets to build a culture of recognition in the workforce guided strongly by the 5 Languages of Appreciation in the Workplace as described by Gary Chapman and Paul White. This approach recognizes that different people internalize forms of recognition differently and that being able to speak a specific recognition “language” to a specific employee can increase the impact of that recognition. The C.A.R.E team made it a priority to continue the practices of employee recognition and self-care during the pandemic, when staffing practices and expectations greatly changed, and individuals were balancing work and life scenarios as never before. This seminar will speak about employee recognition both pre-COVID and during the pandemic, highlighting new ideas for virtual recognition or other ways to recognize employees while upholding safe practices and policies, as well as discussing what appropriate recognition might look like during a pandemic or other time of disaster or change. This seminar is intended for anyone wishing to recognize a direct report or colleague in the lab animal community.

Opioid Analgesic For subcutaneous use in mice and rats only. CAUTION: Federal law restricts this drug to use by or on the order of a licensed veterinarian. LEGAL STATUS--In order to be legally marketed, a new animal drug intended for a minor species must be Approved, Conditionally Approved, or Indexed by the Food and Drug Administration. THIS PRODUCT IS INDEXED--MIF # 900-014. Extra-label use is prohibited. This product is not to be used in animals intended for use as food for humans or food-producing animals. WARNING: ABUSE POTENTIAL, LIFE-THREATENING RESPIRATORY DEPRESSION, and ACCIDENTAL EXPOSURE Abuse Potential Ethiqa XR contains buprenorphine, a high concentration (1.3 mg/mL) opioid agonist and Schedule III controlled substance with an abuse potential similar to other Schedule III opioids. The high concentration of Ethiqa XR may be a particular target for human abuse. Buprenorphine has opioid properties that in humans may lead to dependence of the morphine type. Abuse of buprenorphine may lead to low or moderate physical dependence or high psychological dependence. The risk of abuse by humans should be considered when storing, administering, and disposing of Ethiqa XR. Persons at increased risk for opioid abuse include those with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (suicidal depression). Because of human safety risks, this drug should be used only with veterinary supervision. Do not dispense Ethiqa XR. Life-Threatening Respiratory Depression The concentration of buprenorphine in Ethiqa XR is 1.3 mg/mL. Respiratory depression, including fatal cases, may occur with abuse of Ethiqa XR. Ethiqa XR has additive CNS depressant effects when used with alcohol, other opioids, or illicit drugs that cause central nervous system depression. Because of the potential for adverse reactions associated with accidental injection, Ethiqa XR should only be administered by a veterinarian or laboratory staff trained in the handling of potent opioids. DESCRIPTION Ethiqa XR is an injectable suspension of extended-release buprenorphine. Buprenorphine hydrochloride, an opioid analgesic, is the active ingredient in Ethiqa XR. Lipid-bound buprenorphine hydrochloride is suspended in medium chain fatty acid triglyceride (MCT) oil. Lipids encapsulate the buprenorphine limiting diffusion which provides for larger doses and prolonged action.1,2 Ethiqa XR has a slightly yellow to white opaque appearance. Each mL contains approximately 1.3 mg buprenorphine hydrochloride. The sterile product contains cholesterol, glyceryl tristearate, and buprenorphine hydrochloride suspended in MCT oil. Buprenorphine Formula C29H41NO4

INDICATIONS Ethiqa XR is indicated for the control of post-procedural pain in mice and rats. MOUSE DOSAGE AND ADMINISTRATION Wear protective clothing when administering Ethiqa XR (see Human Safety Warnings). Shake the vial briefly before each use to ensure uniform suspension. If stored refrigerated, bring to room temperature before use. Use aseptic techniques to withdraw the dose into a disposable 0.5 or 1 mL syringe. A 20 to 23 gauge needle should be used for injections due to the viscosity of the drug suspension. The dosage of Ethiqa XR is a single subcutaneous injection of 0.05 mL per 20 gram mouse (3.25 mg/kg body weight). Therapeutic drug concentrations are maintained for 72 hours after the initial dose. If needed, a single repeat dose may be administered 72 hours after the initial dose. Secure the mouse in a scruff-of-the-neck hold. Insert the needle into the dorsal subcutaneous space created by the scruff hold. Inject the entire dose into the dorsal subcutaneous space. An oily sheen may be observed in the dorsal fur of the mouse after injection due to leakage of the oil-based drug suspension from the injection site. The oily sheen may last for 4 to 5 days postinjection. Leakage from the injection site can be minimized by slowly injecting Ethiqa XR into the subcutaneous space. The mouse can be returned to its cage immediately after receiving Ethiqa XR. Do not return any unused drug suspension from the syringe back into the vial. Once the vial is broached, Ethiqa XR can be stored at 15° to 25°C (59° – 77°F) or refrigerated for 28 days. DO NOT FREEZE. RAT DOSAGE AND ADMINISTRATION Wear protective clothing when administering Ethiqa XR (see Human Safety Warnings). Shake the vial briefly before each use to ensure uniform suspension. If stored refrigerated, bring to room temperature before use. Use aseptic techniques to withdraw the dose into a disposable 0.5 or 1 mL syringe. A 20 to 23 gauge needle should be used for injections due to the viscosity of the drug suspension. The dosage of Ethiqa XR is a single subcutaneous injection of 0.1 mL per 200 gram rat (0.65 mg/kg body weight). Therapeutic drug concentrations are maintained for 72 hours after the initial dose. If needed, a single repeat dose may be administered 72 hours after the initial dose. Secure the rat in a passive restraint tube or by holding with a heavy glove with one person to secure the rat and a second person to administer the drug. Insert the needle in the dorsal subcutaneous space. Inject the entire dose into the dorsal subcutaneous space. An oily sheen may be observed in the dorsal fur after injection due to leakage of the oil-based drug suspension from the injection site. The oily sheen may last for 4 to 5 days post-injection. Leakage from the injection site can be minimized by slowly injecting Ethiqa XR into the subcutaneous space. The rat can be returned to its cage immediately after receiving Ethiqa XR. See CONTRAINDICATIONS and Rat PRECAUTIONS for additional information on bedding. Do not return any unused drug suspension from the syringe back into the vial. Once the vial is broached, Ethiqa XR can be stored at 15° to 25°C (59° – 77°F) or refrigerated for 28 days. DO NOT FREEZE. CONTRAINDICATIONS Only administer Ethiqa XR by subcutaneous injection. Ethiqa XR is not intended for intravenous, intra-arterial, intrathecal, intramuscular, or intra-peritoneal injection. Do not use on mice or rats with pre-existing respiratory deficiencies. Do not keep rats on wood chip-type bedding after administration of Ethiqa XR. HUMAN SAFETY WARNINGS Not for use in humans. Keep out of the reach of children. Human User Safety while handling Ethiqa XR: Two trained staff for administration: Ethiqa XR should only be handled and administered by a veterinarian, veterinary technician, or laboratory staff trained in the handling of potent opioids. To prevent human adverse reactions or abuse, at least 2 trained administrators should be present during injection of Ethiqa XR. Protective covering: To prevent direct contact of Ethiqa XR with human skin or mucous membranes when handling the suspension, protective clothing is recommended. Mucous membrane or eye contact during administration: Direct contact of Ethiqa XR with the eyes, oral or other mucous membranes of humans could result in absorption of buprenorphine and the potential for adverse reactions. If accidental eye, oral or other mucous membrane contact is made during administration, flush the area with water and contact a physician. Skin contact during administration: If human skin is accidentally exposed to Ethiqa XR, wash the exposed area with soap and water and contact a physician. Accidental exposure could result in absorption of buprenorphine and the potential for adverse reactions. Drug Abuse, Addiction, and Diversion of Opioids: Controlled Substance: Ethiqa XR contains buprenorphine, a mu opioid partial agonist and Schedule III controlled substance with an abuse potential similar to other Schedule III opioids. Ethiqa XR can be abused and is subject to misuse, abuse, addiction,

and criminal diversion. Ethiqa XR should be handled appropriately to minimize the risk of diversion, including restriction of access, the use of accounting procedures, and proper disposal methods, as appropriate to the laboratory setting and as required by law. Abuse: Abuse of Ethiqa XR poses a hazard of overdose and death. This risk is increased with concurrent abuse of alcohol and other substances including other opioids and benzodiazepines. Buprenorphine has been diverted for non-medical use into illicit channels of distribution. All people handling opioids require careful monitoring for signs of abuse. Drug abuse is the intentional non-therapeutic use of a prescription drug for its rewarding psychological or physiological effects. Abuse of opioids can occur in the absence of true addiction. Storage and Discard: Ethiqa XR is a Class III opioid. Store in a locked, substantially constructed cabinet according to DEA and local controlled substance guidelines. Discard broached vials after 28 days. Any unused or expired vials must be destroyed by a DEA registered reverse distributor; for further information, call 1-833-384-4729. Physician information: Ethiqa XR injectable suspension is a mu-opioid partial agonist (1.3 mg buprenorphine/mL). In the case of an emergency, provide the physician with the package insert. Naloxone may not be effective in reversing respiratory depression produced by buprenorphine. The onset of naloxone effect may be delayed by 30 minutes or more. Doxapram hydrochloride has also been used as a respiratory stimulant. PRECAUTIONS Mice The safety of Ethiqa XR has not been evaluated in pregnant, lactating, neonatal, or immune-compromised mice. As with other opioids, buprenorphine may cause sedation, decreased blood pressure, decreased heart rate, decreased gastrointestinal mobility, and respiratory depression. Use caution with concomitant administration of Ethiqa XR with drugs that cause respiratory depression. The use of paper or soft bedding for up to 3 days following administration of Ethiqa XR should be considered. Normal mice may exhibit an obtunded response to stimuli up to 4 hours after receiving Ethiqa XR. Buprenorphine is excreted in the feces (see Clinical Pharmacology section below). Coprophagy may lead to ingestion of buprenorphine or its metabolites by mice treated with Ethiqa XR and untreated cage mates. Rats The safety of Ethiqa XR has not been evaluated in pregnant, lactating, neonatal, or immune-compromised rats. As with other opioids, buprenorphine may cause sedation, decreased blood pressure, decreased heart rate, decreased gastrointestinal mobility, and respiratory depression. Use caution with concomitant administration of Ethiqa XR with drugs that cause respiratory depression. Rats may exhibit signs of nausea including pica up to 3 days post-treatment. Rats should be maintained on paper or soft bedding to avoid ingestion of wood chip-type bedding after administration of Ethiqa XR. Pica involving wood chip-type bedding can be lethal in rats. Buprenorphine is excreted in the feces (see Clinical Pharmacology section below). Coprophagy may lead to ingestion of buprenorphine or its metabolites by rats treated with Ethiqa XR and untreated cage mates. ADVERSE REACTIONS Mice No adverse reactions were observed in 20 to 25 gram young adult male and female mice after a single subcutaneous injection of Ethiqa XR at a dose 5 times the indicated dose. Laboratory parameters evaluated in the study included hematology and clinical chemistry; histopathology was also performed. In a second study, adult male and female mice received Ethiqa XR subcutaneously at 5 times the indicated dose for three doses at four day intervals. A surgical procedure was performed on the study mice prior to receiving each of the three doses of Ethiqa XR. Mortality was seen in two male mice after the third surgical procedure and dose of Ethiqa XR (total dose of 49 mg buprenorphine/ kg body weight in 8 days). Weight loss has been observed in mice treated post-procedurally with Ethiqa XR. Rats Adverse reactions were evaluated in 180 to 200 gram young adult male and female rats after a single injection of Ethiqa XR. A surgical procedure was performed on the rats prior to administration of a single dose at the intended dose of 0.65 mg/kg or a single dose of 2, 6 or 10-fold excess dose. Adverse reactions also were evaluated in male and female rats administered 2, 6 and 10 times the intended dose for three doses at four day intervals. A surgical procedure was performed on the rats prior to administration of the first of three doses. Laboratory parameters evaluated in the study included hematology, clinical chemistry, urinalysis, histopathology, and bodyweight. Signs of nausea were observed at all dose levels within 24 hours of the dose. Signs included self-licking, self-gnawing and efforts to eat wood-chip bedding. Mortality was seen in 1 of 36 rats exposed to wood chip bedding. Necropsy revealed the stomach and esophagus were compacted with bedding, the bladder was abnormally distended and the urine contained blood. Mortality was seen in 3 of 222 rats treated with Ethiqa XR due to technical complications with serial bleeding of the jugular vein. For technical assistance, or to report an adverse drug reaction, please call Fidelis Pharmaceuticals LLC at 1-833-384-4729. For additional information about adverse drug experience reporting for animal drugs, contact FDA at 1-888-FDA-VETS or http:// www.fda.gov/AnimalVeterinary/SafetyHealth. CLINICAL PHARMACOLOGY3 Buprenorphine can act as an agonist and antagonist at different classes of opioid receptors. Agonism at the mu opioid receptor and, in some cases, antagonism at the kappa or delta opioid receptors are possible underlying mechanisms for the ceiling effect and bell-shaped dose-response curve of buprenorphine. Studies with knockout mice have shown that the antinociceptive effect of buprenorphine, which is mediated primarily by the mu opioid receptor, is attenuated by the ability of the drug to activate the opioid receptor like (ORL-1) receptor. The drug can be described as a ‘full’ and a ‘partial’ agonist at the same receptor depending on the specific assay. There appears to be no ceiling effect for analgesia, but there is a ceiling effect for respiratory depression. Pharmacokinetic studies with bolus injections of buprenorphine in mice and rats provide similar models. After bolus intravenous administration, plasma levels decline tri-exponentially. The drug is n-deakylated in the liver to norbuprenorphine (NBN), an active metabolite. Studies have shown that glucuronide metabolites of buprenorphine and NBN are also metabolically active, and can approximate or exceed the concentration of the parent drug. Un-metabolized drug excreted in the urine and feces one week after injection was 1.9 and 22.4% of the dose, respectively, and 92% of the dose was accounted for in one week.3 Mice Pharmacokinetic parameters of Ethiqa XR were studied in 6-8 week old male and female Balb/c mice following a single subcutaneous injection of 3.25 mg/kg bodyweight. Clinically significant blood levels were observed up to 72 hours after subcutaneous injection. Rats Pharmacokinetic parameters of Ethiqa XR were studied in 8 week old male and female Fischer rats following a single subcutaneous injection of 0.65 mg/kg bodyweight. Clinically significant blood levels were observed up to 72 hours after subcutaneous injection.

Insights, Challenges, and Outcomes When Producing, Maintaining, and Evaluating Severely Immunodeficient Mouse Models 8:00 AM - 10:15 AM/ Room: 3501A Leader/Moderator: Robert S Livingston

Mice with targeted mutations in multiple genes (NOD background; Prkdcscid or Rag1/Rag2; and IL2 receptor gamma) lack mature T, B, and NK lymphocytes, hemolytic complement activity, and have diminished macrophage and dendritic cell function. Severely immunocompromised status renders these animals more susceptible to spontaneous infection by many opportunistic organisms that rarely cause disease in immunocompetent mice. These animals thus pose many unique challenges in relation to production colony management, infectious disease prevention, and animal health monitoring. This seminar will provide insight into management and disease prevention strategies for these immunocompromised mice, including well-intentioned practices that can instigate problems. The targeted audience will be laboratory animal veterinarians, animal care technicians, facility managers, and husbandry and research personnel.

SPECIAL TOPIC LECTURES Charles River Ethics and Animal Welfare Lecture: Optimizing the Care Pathway: A Global Approach to Perioperative Care 11:00 AM - 12:00 PM/ Room: 2501B Speaker: Daniel SJ Pang Moderator: Patricia V Turner Facilitator: Jennifer M Mitchell

Over the last two decades, tools for assessing pain in animals have improved dramatically, applying psychometric approaches to create pain scales that are valid and reliable. These advances provide us with the ability to identify and appropriately manage pain. However, the extent to which such tools are being used is unclear, with the continued use of a one-size-fits-all approach to pain management. This approach overlooks the power of pain assessment to optimize care, providing pain relief when indicated and facilitating a rational approach to pain management. Pain control can also be viewed within the larger context of perioperative care, which includes numerous steps as an animal moves along the care pathway from the pre-anesthetic phase through to recovery and return to normal function. Taking steps to optimize each aspect of this pathway, such as body temperature, surgical technique, and analgesia, promotes a speedy recovery. This focus on optimizing the care pathway is the basis of Enhanced Recovery After Surgery (ERAS), a concept developed in human medicine in the late 1990s. Application of ERAS principles has been embraced internationally (including the USA) and has achieved marked improvements in patient care for a wide range of surgeries (e.g. bariatric, gynecological, intestinal). Inherent to this global approach to patient care is the necessity of monitoring performance to maintain existing standards and drive improvement. Clinical audit is a quality improvement tool used to achieve these goals through collecting and comparing performance data against existing guidelines and benchmarks. Applying clinical audit to patient care is a powerful mechanism for achieving meaningful and sustained change. This presentation will describe a global approach to patient care, facilitated by applying existing and emerging tools. Attendees will learn how to use case examples; attendees will receive a refresher on current tools available for pain assessment in a range of species.

Compassion Fatigue and Job Burnout in the Animal Research Field 11:00 AM - 12:00 PM/ Room: 2501A Speaker: Heather Hersh Moderator: F Claire Hankenson Facilitator: Leah Makaron

Laboratory animal professionals are often drawn to the field by their connection to and compassion for animals and animal welfare. Because they are invested in animal well-being, these professionals are susceptible to compassion fatigue, especially when animals reach humane endpoints and are removed from study. Further, there may be risk for job burnout. These vulnerabilities became even higher during the COVID-19 pandemic. Importantly, although compassion fatigue and burnout are similar, they are quite distinct. Compassion fatigue is defined as an overexposure to suffering and pain that can cause personal stress and a reduced capacity for empathy. In contrast, burnout is emotional exhaustion, decreased professional efficacy, diminished motivation, and lack of empathy brought on by the work environment. Although laboratory animal professionals are at risk for both compassion fatigue and burnout, they often do not receive appropriate trainings to build their resilience and develop coping strategies for these conditions. Additionally, veterinary management and leadership often

struggle to determine how to best support their staff and to prevent compassion fatigue and burnout. This special topic lecture will address these critical topics. The speaker holds a doctorate in psychology and has expertise in this niche area of emotional health support for animal care workers. During this lecture, important distinctions between compassion fatigue and burnout will be highlighted, and practical recommendations will be made for leadership and management to evaluate, assess, and minimize compassion fatigue and burnout across teams. Additionally, for individuals, the talk will provide practical strategies to address compassion fatigue and burnout when they occur. Maintaining emotional well-being in the workplace requires that leadership, the animal care teams, and individuals have strategies and safeguards that allow everyone to thrive professionally and personally while providing high quality care to the animals. The target audience for this lecture is veterinarians, veterinary technicians, and husbandry staff.

Naturally Occurring Large Animal Models of Neurodegenerative Diseases and Gene Therapy 11:00 AM - 12:00 PM/ Room: 3501A Speaker: George J DeMarco Moderator: Stephen I Levin

This lecture will discuss the natural history, model development, and treatment of large animal models for Tay-Sachs Disease (Jacob sheep), Cerebellar Abiotrophy (goat), and Maple Syrup Urine Disease (cattle). Participants will learn about the genetic and biochemical aspects of the diseases to be discussed, clinical course, and use as models for the corresponding human diseases. The development of gene therapy for these diseases, in particular adeno-associated-viral gene therapy, and why these diseases are uniquely suited for gene therapy will be discussed. The target audience will be veterinarians and researchers interested in large animal models and gene therapy.

Wallace P. Rowe Lecture: The Microbiome and Animal Models of Disease, Progressing Beyond Correlations 11:00 AM - 12:00 PM/ Room: 2501C Speaker: Betty R Theriault Moderator: Tiffany L Whitcomb

The genetically engineered mouse has played an indispensable role in the discovery of mechanisms, contributing to health and the pathophysiology of disease. Rederiving genetically engineered mice to germ free (axenic) status allows scientists the opportunity to uncouple genetic modifications from microbiome contributions in animal mod-

els of human disease. Transitioning from specific-pathogen free mouse models to germ free and gnotobiotic models presents challenges and opportunities the laboratory animal care professional is uniquely positioned to inform. This is particularly true for models requiring surgical interventions. This presentation will highlight recent advances in germ free and gnotobiotic models of transplantation, neointimal hyperplasia, and age-related macular degeneration highlighting a role for the microbiome in disease progression. It will also present ongoing challenges in utilizing germ free and gnotobiotic mouse models in discovery of mechanisms by which the microbiome exerts its influence on host health and disease.

PANEL DISCUSSIONS Advancing the IACUC Mission through Metrics

12:30 PM - 2:00 PM/ Room: 2504A Leader/Moderator: Stacy L Pritt Facilitator: Elizabeth A Trumpower Panelist: Stacy L Pritt, Madeline L Budda, Kathryn L Cavanaugh

The collection and reporting of metrics is a form of business analytics management originally designed to promote efficiency in the workplace that dates back to the 1800s. Today, metrics are widely used to actively measure productivity and benchmark goal achievement. Metrics are also a mainstay in laboratory animal science and are not only leveraged as a tool to improve operational performance but also to provide valuable comparisons between research animal programs. There are many ways in which IACUCs self-assess adherence to regulation (e.g., program review, semi-annual inspections). Over time, the IACUC community has developed its own set of commonly used metrics for quantifying and comparing program aspects such as program size, scope, and methods of review. These self-assessment methods and metrics, however, generally focus on how well IACUCs are ensuring animal welfare through their mandated functions and do not include an assessment of the efficiency and effectiveness of the processes used to implement the regulations. Furthermore, these commonly reported metrics, such as the number of protocols managed by an IACUC, have not been standardized across institutions, nor has there been a critical review of the value of the metrics. This panel discussion will analyze the current state of metrics within the IACUC community and how individual IACUC programs can optimize metrics measurements to advance their objectives and review how to appropriately apply metrics within an IACUC program to facilitate the

signed, performance-based studies can provide practical and realistic answers to this critical area. Audience questions and discussion will be encouraged throughout the session. Panel participants have many years of experience with different types of housing and are knowledgeable about NHP behavior performance standards. The target audience includes all members of the NHP user community who want to enhance their knowledge of NHP housing design and promote the welfare of NHPs with various housing design features. This Panel Discussion is sponsored in part by Association of Primate Veterinarians (APV).

This session focuses on future nonhuman primate (NHP) housing designs that promote animal welfare and facilitate study procedures. Housing space allotments and differences between North America and European standards have indicated the need for well-designed, performance-based studies to access space utilization and welfare. Discussions will focus on key design considerations of existing and new mobile housing and fixed housing units for both New World and macaque species. Behaviorists with NHP expertise will discuss how animal environments and cage design impact species-typical behaviors and improves welfare. Results from an Association of Primate Veterinarians/American Society of Primatologists survey on indoor macaque housing standards will be included. Current housing enhancements for specific study related aspects (e.g., aging studies, neurological studies, and toxicology studies) will be discussed. Commentary on ways to add structural complexity (e.g., visual barriers and enhanced vertical space) will be presented. Additionally, the panel will discuss overall space needs determinations, and how well-de-

The New 3Rs: Reduce, Reuse, and Recycle—Going Green in the Vivarium 12:30 PM - 2:00 PM/ Room: 3501H Leader: Jeffrey D Wyatt Moderator: Dana M LeMoine Facilitator: Suhrim Fisher Panelist: Jeffrey D Wyatt, Michael J Huerkamp

It is widely known that laboratory animal facilities create lots of waste, including water, PPE, and bedding. It is also widely perceived that it is impossible to reduce, reuse, and recycle waste produced from the vivarium, while some of us religiously reduce, reuse, and recycle at home. With some groundbreaking creativity and thinking outside-ofthe-box, this session will share some of the challenges and success stories of going green in the vivarium. The targeted audience is all AALAS attendees who are interested in learning about sustainability in the vivarium, facility managers, program directors/administrators, and any other AALAS attendees who would like to go green in their

1:00 PM - 5:00 PM/ Room: 2203 Leader: Cholawat Pacharinsak Faculty: Patrick E Sharp Workshop Fee: $150 Workshop Limit: 30

General anesthesia alters multiple physiologic responses of the body. Therefore, to have safe anesthesia, anesthetists should monitor patients starting from premedication to recovery. Monitoring requires anesthetists to have a thorough understanding of the various monitoring equipment used, including the interpretation of information generated. One big advantage of anesthetic monitoring is to alert anesthetists regarding arising complications so anesthetists can take the necessary actions to correct the complications before they become irreversible. This workshop will focus on basic laboratory animal monitoring methods, including anesthetic depth, ECG, blood pressure, ETCO2, %SpO2, and body temperature. This dry workshop is suited for veterinarians, veterinary technicians, IACUC members, and scientists. This Workshop is sponsored in part by Kent Scientific

This session will benefit those involved with animal facility design and operations by describing the process, decisions, and technologies involved in the design and construction of animal facilities. The workshop will begin with a discussion of the facility design process—who should be involved, the objectives and level of effort by stakeholders, milestone decisions to be reached, and anticipated duration of the various process phases. Current trends in the industry will be explored through discussions about planning, interior construction, acoustics, and finishes. Throughout the session, we will be framing the discussion from the owner’s perspective and their experiences in the real world. We will include critical mechanical, electrical, and piping design and operations. This section will focus on the MEP risks associated with compromised animal welfare, loss of research and facility resiliency, and how engineering decisions affect each of these parameters. The lessons learned will help enable participants to make more informed decisions as they develop and operate their own facilities. Conversations will focus on vivarium operations and facility sanitation and safety. We will also discuss strategies regarding energy and water conservation that are being effectively implemented in animal facilities and the derived long-term benefits. The target audience for this workshop is anyone involved with animal facility design and operations.

Shake It, You Won't Break It! Rodent Health Monitoring Using Media Agitated with Soiled Bedding 2:45 PM - 5:00 PM/ Room: 2501A Leader/Moderator: Robert S Livingston Facilitator: Marni Romano

Regular monitoring of rodent colonies for infectious agents is critical to identify those that may adversely affect the health status of research rodents or provide a source of experimental variability. Over the past decade, PCR testing of dust from the return air systems of open airflow IVC rack systems has provided an alternative approach to rodent health monitoring. However, this method is only applicable in IVC systems that do not filter the return air at the cage level. Participants will be shown data on experimental and real-world evaluations using PCR testing of a variety of media agitated with composite soiled bedding from rodents for detection of murine pathogens. This approach can be used as an adjunct to or possible replacement for soiled bedding sentinels and has the advantage of being applied to any rodent caging system. The target audience includes veterinarians, facility managers, and technical personnel who manage health monitoring programs.

SEMINARS Coronaviruses: Troubling Crown of the Animal Kingdom 8:00 AM - 10:15 AM/ Room: 2501B Leader: Nancy D Hitt Moderator: Ginger Tansey

In late 2019 alarms were raised about a mysterious virus responsible for numerous deaths in China. As we now know, this novel coronavirus rapidly became a worldwide pandemic infecting approximately 120 million people resulting in 2.6 million deaths by early March 2021. The coronavirus was found to be like the severe acute respiratory syndrome virus (SARS) outbreak in 2003 and was named SARS-CoV-2. The severe disease was termed COVID-19, Coronaviruses (CoVs) have been described since 1939 and are known to infect a wide range of wild and domestic species, where they have had a significant impact in several agricultural, pet, and wild species. Their large genome, reduced dependency on host cellular proteins, and frequent recombination allow them to successfully cross species barriers, adapting in some cases to humans. The study of these animal diseases has provided a wealth of understanding of the viral biology and pathogenesis and assisted in the unprecedented development of the SARS-CoV-2 vaccines. We will briefly review what is known about the origins, transmission mechanisms, pathogenesis, clinical signs, treatment, and prevention of coronaviruses found in other mammals including wild, domestic, and laboratory animal species. The final two presentations will focus on characterization of SARS-CoV-2 animal models, including imaging modalities in nonhuman primates used in disease and vaccine studies, as well as existing coronavirus vaccines for other animal species.

SPECIAL TOPIC LECTURES Indexing a Drug for Minor Species: The Injectable Anesthetic Alfaxalone as a Case Example 11:00 AM - 12:00 PM/ Room: 3501A Speaker: Kirby Pasloske Moderator: Christina L Schoepfer Facilitator: Brian Mahan

Indexing is the process in the US to legally market unapproved new animal drugs for non-food producing minor species. To be placed on the Index, the drug must have its safety and efficacy affirmed through an alternative FDA process through the Minor Use Minor Species (MUMS) group. A drug that is indexed is not registered. The FDA recognizes the challenges obtaining registration for products in species too rare or varied for traditional safety and effectiveness studies. In many cases, minor species drug products are intended for uses that cannot reasonably go through the standard drug approval process (New Animal Drug Application or NADA). Instead of a NADA number we have a Minor Species Index File number or MIF. To have a product on the Index is especially helpful to individuals treating animals or classes of animals representing markets too small to support the costs of the drug approval process. In this lecture the Indexing of the injectable sedative/anesthetic alfaxalone will be discussed as a case example. This will include discussion on the partnership with MUMS group to Index the product, formation of the Expert Panel to review efficacy

Nathan E Brewer Lecture

11:00 AM - 12:00 PM/ Room: 2501B Speaker: William J White Moderator: Jane Olin

Laboratory animal science and medicine has evolved over time by building on science, as well as making some key assumptions about animal care and use. We have gauged animal needs and preferences in the context of our ethical values and stewardship of the animals. Standards for their care and use have become more detailed while still being able to be adjusted by professional judgement to achieve the best balance between research requirements and optimal animal welfare. This presentation will explore considerations for setting and modifying guidance for animal care and use as well as evaluating studies and assumptions used to support such guidance. This Special Topic Lecture is sponsored in part by AALAS Awards Selection Committee (ASC).

Perspective on the Future of Animal Research

11:00 AM - 12:00 PM/ Room: 2501C Speaker: Edwin S Kreitlein Moderator: Marcel I Perret-Gentil Facilitator: Danielle Henry

Advancements in technology, such as cellular imaging and computer simulation, have dramatically increased our understanding of the anatomy and physiology of both humans and animals at significantly greater detail. The knowledge the scientific community has obtained about how living systems of humans and animals intersect has grown exponentially over the last 20 years with the advent of gene mapping, nuclear medicine, and advanced magnetic resonance imaging. It has been surmised that this understanding will ultimately decrease the need to conduct human health investigations in animal models. Many predict that research testing and validations can and should be conducted in silico in lieu of in vivo with the continued goal of advancing the 3Rs. To address this and other vivarium related issues, a colloquium of several experts in animal research was assembled in the fall of 2020 to discuss the future of animal investigations, and how it may be conducted in the next 30 years. To facilitate discussion, three key topics were addressed related to the vivarium of the future: challenges, changes, and methods. This lecture is a report of that meeting and the issues that were discussed in detail by the 13 experts

who contributed to the conversation. Participants can expect to learn about critical issues facing vivaria today and into the future, and ways to mitigate the challenges through appropriate change. Methods to overcome the barriers that prevent successful results will be shared by using images, charts, and graphs that will help validate the options. The primary target audience for this session will be vivarium managers and directors, lab animal veterinarians, animal research institution owners, health and safety officers, vivarium planners and designers, and IACUC personnel.

Responsibility of the IACUC for Ensuring Reproducibility, Scientific Rigor, and Transparency 11:00 AM - 12:00 PM/ Room: 2501A Speaker: Lauren Danridge Facilitator: Daniela A Miller

Amidst concerns about reproducibility, scientific rigor, and transparency (RSrT) in all areas of research, recent attention has been given to whether the IACUC shares responsibility in ensuring RSrT. IACUCs are expected to apply the 3Rs during review and approval of animal use applications and should “evaluate scientific elements of the protocol as they relate to the welfare and use of the animals”, according to the Guide. But should IACUCs also ensure the proper application of the experimental method? In the context of reducing burden, what additional IACUC responsibilities make sense, if any? Toward the goal of establishing the methods by which IACUCs help ensure RSrT, and the roles IACUCs should play, we will discuss the common variables reported as contributing to RSrT concerns, review how the regulations are applied in the IACUC review of animal activities, describe some recent literature and initiatives and compare IACUC functions and regulations to the concerns reported as contributing to RSrT. The target audience is IACUC administrators, chairs, and members.

all races as one minority category), disabilities, and more. Such broad-brush approaches may have some utility but fail to address the unique disparities of particular minority groups. In this panel discussion we take a deep dive into the persistent racial injustices facing African-American communities in the United States. Reflecting on the “racial revolution” sparked by racial brutality incidents during the global COVID-19 pandemic, we will review the laboratory animal science industry’s current situation. How far have we come? Where can we go from here? Where should we be going from here? Topics to begin the conversation include acknowledgment for African American contributions in laboratory animal science. We will talk about true equity and consider what is working and not working in organizations. How do we make it right? What does diversity look like to you? What are you doing to make it happen? We will share authentic, tangible strategies to improve diversity, equity, and inclusion in the workplace. As we transition into a post-COVID era, the audience is invited to advance the racial justice dialogue and take the next step on our inclusive journey to better. A DE&I discussion for everyone, successful diversity (recognizing and respecting everyone’s unique abilities and attributes), equity (fair and respectful treatment of all people) and inclusion (everyone feels respected, accepted and valued) requires everyone come to the table.

Efficient Management of Controlled Substances in the Lab Animal Research Facility Using Paper and Automated Systems 12:30 PM - 2:00 PM/ Room: 2504A Leader: Matthew Ruiter Moderator: Jose R Gadea Panelist: Iris D Bolton, Brad Gien, Jessica L Hendricks, Craig C Sem

The use of controlled substances (CS) in lab animal research is strictly regulated. To tackle the opioid crisis and eradicate drug diversion, the Drug Enforcement Agency (DEA) closely monitors the manufacturing, distribution, and use of CS. With increased regulation, the use of CS in animal research has become a confusing, stressful, and labor-intensive process. Authorized agents are directly responsible for the use, storage, and security of all CS on site, and they find it increasingly difficult to manage the process effectively, which includes maintaining accurate and detailed records to ensure compliance. Currently, there is no perfect system for managing CS efficiently in the lab animal research setting. Most facilities store CS in a combination-lock safe or cabinet with a one- or two-key security system in place that can only be accessed by authorized personnel. The use and record-keeping process relies entirely on manual data entry, which is labor-intensive and prone to miscalculations and human errors. This panel will discuss the unique challenges faced by those working with CS in research, and how they address their concerns using manual and electronic data collection systems. What are the DEA requirements for storing CS? What to expect during an audit? How effective is your diversion control program? What options are there for managing CS? These and other questions will be addressed by panel members, who include professionals from a range of industry sectors (including CROs, animal suppliers, and big pharma) with extensive experience with DEA regulations and CS management. Participants will gain valuable insights to help them implement and manage a successful and efficient CS program at their facilities. They will learn about DEA regulations/ compliance, best practices for CS record-keeping, reducing the risk of drug diversion and minimizing the chance of inspections. The target audience is facility managers, animal care program directors and supervisors, veterinarians, IACUC members, research personnel and compliance staff.

Not All Individually Ventilated Caging Systems Are Created Equal 12:30 PM - 2:00 PM/ Room: 3501H Leader/Moderator: Scott E Perkins Panelist: Scott E Perkins, Neil S Lipman, John J Hasenau, Michael J Huerkamp

The scientific community uses individually ventilated caging (IVC) systems in a general manner. However, the use of these general terms does not adequately describe the caging systems. The type of IVC used may impact facility design, operational planning, and, most importantly, study reproducibility. We will review a formal classification system that encompasses an array of different approaches and technologies, each with different risk/benefit tradeoffs. There are six parameters in the classification system, including airflow mechanics, rack ventilation, air change rates, cage design, intracage air flow dynamics, and other parameters when assessing microenvironmental conditions. These six parameters should be considered when evaluating IVC systems and the methods employed to meet performance specifications and comparing different system types between studies. Active audience participation is expected. The target audience is veterinarians, research scientists, facility managers, reviewers of scientific articles, journal editors, IVC manufacturers, and others interested in IVC systems.

Working with Emotional Labor: An Interactive Discussion 12:30 PM - 2:00 PM/ Room: 3501G Leader: Bella J Williams Moderator: Kathryn Bayne Facilitator: Paula A Clifford, Matthew J Gallacher Panelist: Bella J Williams, Keith Davies, Anneke Keizer

Emotional labor can be experienced by individuals when their day-today work necessitates generating unnatural (for them) feelings and thereafter, acting out those feelings as a means of connecting with others, alongside meeting the needs of their workplace. Frequently overlooked and undervalued, the emotions experienced by those working in animal facilities are key to their role. The way that all staff roles manage, express, and share their emotions with one another can lead them to bond closely, care for their animals with compassion, and is the basis of institutional care. When not provided with outlets, support, or recognition of their emotional challenges, both daily work routines and institutional culture can be affected, leading to the hallmarks of compassion fatigue from emotional burn-out to sickness and stress. The unprecedented COVID-19 pandemic contributed to and in some situations exacerbated the emotional dissonance felt by care staff, as institutional strategies stretched the reality and efficacy of their cultures of care. In this session three speakers introduce key approaches to emotion-work and invite the audience to discuss scenarios that mean engaging with and reflecting on the complex emotions involved in animal care. Together, we will consider the value of emotional labor and how staff can be supported to deal with emotional challenges including grief and loss. Through interactive tools and facilitated discussion, experts in this field will lead a conversation about how to deal the tricky aspects of care, and to think deeply about how to provide support where it is most needed. Issues associated with the current pandemic might emerge and while there is rarely a right or wrong approach to these emotion-centered issues, group discussion can help us to explore our own and understand different approaches to see emotionally challenging work and care as an asset, rather than a cost, of working in an animal facility. Those familiar with and those completely new to this topic will have the opportunity to share experiences and learn from one another in approaching emotional dimensions of animal-care work. They will learn new ways

WORKSHOPS 1:00 PM - 5:00 PM/ Room: 2205 Leaders: Clifford R Roberts, Alf Johnson Faculty: Jo R Craig, Elizabeth V Roberts Facilitator: Jessica T Hunt Workshop Fee: $150 Workshop Limit: 50

How do you identify and resolve conflicts in your organization? How do you build better teams? This workshop engages participants in identifying ways they can become more effective and efficient in their responsibilities as leaders. We will present the process of developing core values, associated attitudes, and behaviors necessary for effective communication. We will focus on the importance of using shared core values to build teams that collaborate and nurture camaraderie as well as enhance positive relationships. Using the techniques presented, the workshop participants will identify a set of core values with defined attitudes and behaviors that will be applied to a case-example. Specific learning objectives anticipated are creating and implementing core values to enhance staff engagement identifying, resolving conflicts and “undiscussables”, developing novel approaches to enhancing staff productivity, ownership of responsibilities, and understanding how to create effective communication networks that include the provision of constructive feedback. The target audience is directors, managers, supervisors, and staff in training for those positions. This Workshop is sponsored in part by University of California San Francisco.

W-10 Occupational Health and Safety Considerations in Animal Research: Learning through Interactive Case Studies

The animal research environment poses a multitude of potential risks to personnel health and safety. In partnership with environmental health and safety professionals, animal care and support personnel are instrumental in identifying and controlling these risks to ensure a safe environment for themselves, their staff, and others who enter or work within animal facilities. This workshop will focus on the identification, assessment, and control of biological, chemical, radiological, and physical hazards commonly encountered in animal research programs. Topics that will be discussed include how to conduct a risk-assessment; management of animals administered infectious agents and chemicals; nanoparticles; humanized animals; ergonomics; equipment-related hazards; and safe housing and handling of agricultural, aquatic, nonhuman primate, and wildlife species. The workshop will be highly interactive, providing opportunities for participants to work in small groups and participate in discussions using webbased polling and survey tools. Through a mixture of case studies, group discussions, and interactive exercises, participants will evaluate real-world examples and be guided through strategies for identifying potential hazards, assessing the magnitude and extent of induced risks, and developing effective and cost-efficient control measures that protect the safety of workers, animals, and the environment. The targeted audience includes vivarium managers, supervisors, lead technicians, trainers, animal care and veterinary technicians, as well as biosafety professionals.

Once in a Century Event: Lessons Learned from the 2021 Texas Snowstorms

SEMINARS

In 2021, and in the middle of the COVID-19 pandemic, Texas was hit with not one, but two significant snowstorms within just two days in mid-February. Such snowstorms are rare events in Texas, occurring only once every few years. However, the two back-to-back snowstorms, combined with several days of below freezing temperatures, resulted in a weather event that was the worst on record for nearly 100 years. Unfortunately, utility providers and structures in Texas, including homes, universities, and other buildings, were not equipped to handle the aftermath of the accumulated ice and energy demands. We will critically examine the storms, their impact on operations both during and afterwards, and how the IACUC can help support disaster recovery. First, a time course of the storm and infrastructure failings, including the energy grid failure, widespread plumbing problems, compromised water supply, and resulting impacts on staffing will be provided. Next, facility management during the storm and its aftermath will be explored. Specifically, shortcomings in existing facility disaster plans will be reviewed considering the multiple layers of system failures throughout the state and the lingering consequences, which include indoor flooding, staffing shortages, and supply chain issues for water and food for both humans and animals. Due to their unique housing requirements and the challenges, they posed during the snowstorms, a special focus will be given to zebrafish and one facility’s successful attempts to ensure appropriate housing temperatures and water quality during the weather event. The seminar will end with an assessment of the effect of the storms on the IACUC, from immediate operational impacts to required reporting to post-disaster support of researchers and the animal care and use program. Seminar attendees will learn how to update their disaster plans to account for out-of-theordinary and prolonged weather events that result in infrastructure failures and supply shortages throughout a large geographic area. The target audience includes veterinarians, animal facility managers, animal husbandry staff, and IACUC staff.

Bench to Bedside: Optimizing the Translational Relevance of Preclinical Animal Modeling 2:45 PM - 5:00 PM/ Room: 2501C Leader/Moderator: William P Feeney Facilitator: Judi A McNulty

The translational relevance of animal models is a critical component of many basic science and biomedical research programs. Improving the translational relevance of nonclinical animal modeling strategy represents one approach actively being pursued by many scientists to reduce attrition in drug discovery and development. The translational relevance of in vivo models is also very important for basic and applied research and is essential for advancements in science and medicine. The proper selection of animal models and biomarker strategies, as well as the use of robust study design, contributes greatly to the development of effective nonclinical models and appropriate translation in the clinical setting. In addition, enhanced understanding of target mechanisms, disease pathways, and safety liabilities are additional factors that can contribute to improved nonclinical models. We highlight approaches that can be used to optimize nonclinical animal modeling strategies and improve clinical predictivity. The session will review principles of animal model selection and approaches for optimizing the translational relevance of in vivo models used in disease research. Several case studies will be presented to illustrate core principles and a question-and-answer session will encourage audience participation in a discussion of how to best optimize animal model election to advance biomedical research. The seminar will have relevance for research biologists, laboratory animal scientists, veterinarians, veterinary pathologists, and biostatisticians.

the most information possible from clinical pathology samples. Our final speaker is an operations, business, and product manager who will provide examples of how the 3Rs were put forward not just to assist investigators in finding and using currently available techniques but to encourage the development of yet unknown tools and methodologies. Our target audience is anyone interested in practical applications of the 3Rs, including veterinarians, investigators and technicians working in research and IACUC veterinarians, reviewers, faculty, and staff.

Speakers/Topics:

The principles of replacement, reduction, and refinement originally surmised by Russel and Burch in 1959 are as applicable today as they were then. As stewards of laboratory animal medicine and research, these principles should guide us in the decision-making process to use animals in research, testing, and teaching. WE will provide resources, tips and techniques, and direct application of these principles to various aspects of laboratory animal medicine. We will encourage questions from the audience, allowing all attendees to come away with practical pearls of wisdom to benefit the laboratory animals that we breed and care for. To accomplish this, we will provide a general overview and guidance from the North American 3Rs Collaborative on resources available for the development and design of animal studies. A Fellow from the Academy of Toxicological Sciences (ATS) will speak on pragmatic approaches to apply the principles of the 3Rs in the drug development process, including the introduction of novel in vitro and mathematical models of bone marrow toxicity to decrease animal use. We will have a toxicologic clinical pathologist discuss best practices for managing low sample volumes in hematology and chemistry testing in rodents and provide practical tips on obtaining

SEMINARS Electronic Medical Records and Advance Data Reporting for Laboratory Animal Medicine 8:00 AM - 10:15 AM/ Room: 2501B Leader: Zachary T Freeman Moderator: Catherine Si

Electronic medical records (EMR) systems have become the standard of care in human and veterinary medicine. These systems have multiple potential benefits including reduced reliance on paper, improved access, and reliability of medical related information. The prevalence of EMR in laboratory animal medicine is increasing, yet there are many challenges for how to apply these systems including the wide array of species and the unique nature of our client patient interactions. The decision to use out-of-the-box solutions or developing your own system requires consideration of multiple pieces of information. In addition to allowing for tracking individual health related events, EMR also allows for the accumulation of large amounts of data. A critical task then becomes understanding how to develop data tools to facilitate the use of this data for users of all experience levels for clinical and programmatic purposes. These tools can offer multiple benefits to improve clinical medicine including both real time and retrospective assessment of individual cases and programmatic concerns. These systems also must be compliant with regulatory requirements for record keeping (e.g., USDA, PHS, FDA). We will discuss different types of Animal Welfare, Regulatory Compliance, and Public Education

Refining Mouse Handling: Why and How to Use Non-aversive Handling to Picking Up Mice 8:00 AM - 10:15 AM/ Room: 2501C Leader/Moderator: Megan R LaFollette Facilitator: Sarah E Thurston

Data indicates that traditional methods of picking mice up by the tail are aversive, inducing stress and anxiety which compromises animal welfare, introduces variability, and can impair study reliability and replicability. Such negative effects can be avoided or substantially reduced by instead using tunnel handling tunnels or cupped hands (i.e., non-aversive handling). The welfare benefits persist even after repeated procedures (i.e., restraint, injection, anesthesia). Many research facilities in the UK and Europe have switched to using non-aversive handling methods, but adoption and implementation rates in the United States remain low. Seminar participants will learn both why and how to switch to non-aversive handling practices at their institutions. Common misconceptions and concerns about non-aversive methods of picking up mice will be addressed. Implementation tips and tricks will be given by large academic and pharmaceutical institutions in the United States that have successfully made the switch. Finally, results from a large-scale survey about non-aversive handling will be presented. The target audiences for this presentation are research staff, IACUC members, animal care staff, veterinarians, and vivarium managers that work with mice.

SPECIAL TOPIC LECTURES The Biggest Threat to the Future of Biomedical Research 11:00 AM - 12:00 PM/ Room: 2501A Speaker: Cindy A Buckmaster Moderator: Rick VanDomelen Facilitator: Steve Burkholder

Laboratory animal breeders are an essential part of the health research and discovery process. Animal rights groups continue to attack lab animal breeders in a variety of ways to harm them financially and ultimately close their doors. With so few lab animal breeders in America, eliminating any source will have a significant negative impact on the research community’s ability to obtain animals for studies. Animal rights groups believe that if they can eliminate the businesses that produce animals for research, they can eliminate animal studies completely. Unfortunately, many CROs, universities, and pharmaceutical

66

companies are unaware of the ongoing efforts of animal rights groups to eliminate lab animal breeders, leaving the people they rely on for animals to fight this battle alone. The historic tactic of staying under the radar is simply not working. Class A breeders need the support of the biomedical research community to ensure that their necessary work can continue. And we are closer to losing this privilege than most are willing to admit. The purpose of this presentation is to better inform the research community of this ongoing threat and to provide advice on what the research community can do to get involved and help defend their ability to continue to do their research. The target audience for this session includes all members of the research community, including those representing organizations with business interests or research requirements that depend on the availability of animal models either directly or indirectly.

The National Bio and Agro-Defense Facility: Maximum Biocontainment in Manhattan, KS

The target audience will be veterinarians, technicians, scientists, and laboratory animal professionals who are interested in high-level biocontainment, vaccine development, global food security, and public health. The National Bio and Agro-Defense Facility, or NBAF, is a worldclass science facility for large animal agricultural research, training, and diagnostics being built in Manhattan, KS that will be owned and operated by the U.S. Department of Agriculture (USDA). NBAF will replace the aging Plum Island Animal Disease Center, a biosafety level-3 facility that is more than 65 years old. In the facility, USDA’s Agricultural Research Service and Animal and Plant Health Inspection Service will conduct comprehensive research, develop vaccines and antivirals, and provide enhanced diagnostic and training capabilities to protect the U.S. against transboundary, emerging, and zoonotic animal diseases that threaten our food supply, agricultural economy, and public health. According to the World Health Organization, more than 70% of new and emerging infectious diseases in humans are zoonotic. NBAF will be the first in the U.S. to provide maximum biocontainment (biosafety level-4) laboratories capable of housing large livestock to develop vaccines and diagnostics for zoonotic diseases. Through these initiatives, NBAF will support global health and food security. NBAF will be a critical component of USDA’s priority to develop vaccines and countermeasures for — as well as the early detection of — diseases that threaten livestock, other animals and food from the nation’s farms and fields. The speaker will present NBAF’s mission and vision, review the development timeline, discuss facility features and science programs, and offer an update on NBAF’s operational status and hiring to date. This Special Topic Lecture is sponsored in part by American Society of Laboratory Animal Practitioners (ASLAP) and American College of Laboratory Animal Medicine (ACLAM).

What Operational Excellence Looks Like in a High Stakes Environment 11:00 AM - 12:00 PM/ Room: 2501C Speaker: Sharron M Kirchain Moderator: Renee L Thompson

Laboratory animal programs are taking note of well-developed high reliability organizations (HROs) and applying the methodology in their vivaria. HROs are those which operate in an environment where errors and adverse events can have a disproportionate impact (such as airplane crashes, medical errors in hospitalized patients, and adverse animal welfare incidents in research facilities). Most, if not

A A LAS 7 2 ND NATIO NAL MEETI N G


all, laboratory animal programs have experienced an undesirable outcome in one way or another. Consider an animal welfare breach or regulatory noncompliance you have been faced with or have heard about. How did you or the people involved react? Many people have an instinctual reaction to these undesired outcomes and may be quick to place blame on a person rather than digging deeper into the system which created the environment conducive to error. Operational excellence is all about continuous improvement, and in this session the audience will learn about applying high reliability processes right in our own vivaria to achieve better outcomes. Topics will include evaluating system issues and identifying areas of risk, as well as the human behavior factor. Deconstruction of the undesirable outcome is one step in the larger framework of building a proactive program to decrease adverse events in the long run. We’ll learn to think proactively by identifying risks first while creating a culture that embraces comfort in talking about errors, as well as a strategy in identifying and mitigating future risk.

PANEL DISCUSSIONS Document Mindfulness: Best Practices for Creating Clearer, Better Animal Health Documents to Maximize Welfare and Minimize Misuse

12:30 PM - 2:00 PM/ Room: 2503A Leader/Moderator: Paula A Clifford Facilitator: Annabella J Williams Panelist: Thomas T Chatkupt, Allyson J Bennett, Kimberly C Ray Animal health records play a key role in ensuring appropriate care for research animals. Clear and concisely written documentation helps

#

OCTOBER 21, 2 0 2 1

veterinary staff identify and treat health issues in their early stages. Well-kept records may also be of critical importance when research results are being analyzed for publication. However, incomplete records that lack important context or feature outdated lab jargon can cause problems. They can delay the identification of health problems and impact the health and well-being of animals. There are significant additional risks when animal health records are not well documented. Because these items can often be obtained via public records requests, substandard notes can be more easily misinterpreted or misused by those opposed to biomedical research in animals. Likewise, written communication regarding animal health, such as email, maybe subject to public records requests, and seemingly benign language maybe misappropriated. During this session, participants will learn the most common forms of poor documentation and the problems that can occur when clear, concise records are not maintained. Information about the kinds of materials commonly requested will be shared. This is a growing challenge because research opponents are increasingly using FOIA and public records requests in their campaigns. Case examples will show how data have been misused or misinterpreted in the past, damaging public opinion and threatening future biomedical progress. Advice and examples of strategies for improving animal health documentation will be discussed. Resources for continuing staff education to improve documentation and possible approaches for situations where documentation obtained via records requests is misused or misinterpreted by research opponents will be presented. The target audience is anyone in the research facility that is responsible for animal care and use documentation.

Working in the lab animal research field with nonhuman primates presents interesting and unique challenges. We have a regulatory and moral responsibility to provide them with opportunities to express species-typical behavior, but we also know they need to be accessible for research needs, observations, husbandry, and veterinary care. How do we care for these animals, create unique housing environments, minimize restraint or stress associated with study procedures, and stay within timelines and budgetary concerns for conducting research? It is an important responsibility of each institution to challenge preconceived notions that may limit opportunities to enhance welfare. Challenging historical mindsets and removing roadblocks that impede change, ensures we continually raise the bar to provide for species specific needs without compromising research goals. Presenters on this topic will illustrate ways that they have overcome historical mindsets and preconceived notions that science will be disrupted. Examples will be shared on how to conquer limitations in caging, space, and costs. Descriptions will be given of how animals enrolled in intensive research protocols (critical care, controlled intake, device/hardware and prosthetists), can still have opportunities that meet their species and social needs, how operant conditioning can be used to improve the animal experience and operational efficiency as a part of the research plan, and how these duties can be performed without special training as a component of the animal care program. Perseverance of animal care professionals to make such refinements contribute to the quality of care provided to laboratory animals. These examples will be shared as a powerful tool to support others in the industry whose programs may have encountered similar barriers with “this is how we’ve always done it” or “it will not work” type of thinking.

CUSP: An Institutional Level Approach to Addressing Administrative Burden

12:30 PM - 2:00 PM/ Room: 3501G Leader/Moderator: Scott D Bury Panelist: Scott D Bury, Susan Glowacz, Meredith L Moore, Thomas E Todd

The Compliance Universal Standardized Protocols (CUSP) project is an online repository where institutions can share standard procedures used in animal care protocols with the broader animal welfare compliance community The project is supported by the Federal Demonstration Partnership (FDP), OLAW, and the USDA as a burden reducing inititive of the 21st Century Cures Act. A working group, representing more than 40 institutions, has been formed to support site design and development. The group has made significant progress in developing this resource over the past year with plans to for the site to go live in 2021. This session will provide participants with an overview of the project, including responsibilities of participants using the system, how to implement and use CUSP at your institution, how CUSP can be used by animal care staff and veterinarians, a demonstration of the test site, and an update on the status of the project.

PS3 Husbandry and Veterinary Considerations when Facilitating Gut Microbiota Research

Center for Comparative Medicine, Mass General Hospital, Charlestown, MA; 2CCM, Massachusetts General Hospital, Charlestown, MA 1

In March 2020, COVID-19 forced our institution, like so many others in our industry, to make major changes quickly to the way we operated our facilities and provided the care and services to our research community. Contributing factors included but were not limited to 1) a limit of onsite personnel to essential employees, 2) a limit of research efforts while supporting new research associated with COVID-19, 3) new 6-ft minimum physical distancing practices, 4) continuous mask wearing, and 5) accommodations associated with greater than 6 feet distancing when eating without a mask. These mandated safety measures required a quick and drastic change to staffing numbers and scheduling. We follow a lean management operations business philosophy which proved to be a key contributor to successfully demonstrate the required agility necessary to meet the emerging and rapidly changing mandates. These critical management principles and tools facilitated our ability to make streamlined changes from a 5- to 7-d workweek; established mechanisms for collecting and sharing employee feedback; supported evaluation of performance standards for changes to rodent cage change practices; and allowed for constant metric collection. PS2 How to Find a Project Management and Scheduling Tool that Works for your Team A Holk*, RE Cooper Physiology, Lovelace Biomedical, Albuquerque, NM Research using animal models is complex and requires the coordination of many uniquely skilled individuals, including technicians, investigators, administrators, and clinicians. Organizing such a large group of people toward a common goal can be a challenging and at times overwhelming process. At a midsized CRO scheduling 10-20 new studies a week with 200 personnel across 10 departments, miscommunications between teams, ineffective scheduling programs, and rapidly evolving study schedules led to a search for more inclusive and adaptive scheduling tools that both address traditional project management needs and meet the more unique challenges common to the animal science industry. We used 7 major criteria to compare some of the most popular project management tools on the market, including the ability to incorporate into current workflows, automation, flexibility to meet a wide range of needs, ease of use, processing power to handle large studies including interdepartmental coordination, customer service, and affordability. There are limited tools that are focused on the specific complexities of organizing and scheduling people around animal work. However, based on the criteria we set forth, a small handful of tools struck a successful balance between affordability and functionality, and were translatable from the standard corporate model to animal science teams. While many tools available offered beautiful graphics and user-friendly technology, the tradeoff was oftentimes failure to accommodate a wide variety of study designs or to handle large, interdepartmental studies. Customized solutions to these issues were often available but cost-prohibitive. We identify some of the unique challenges encountered when applying project management tools to animal science teams, discuss the features of some of the most popular programs available today, and characterize the common pitfalls to avoid when looking for a

P Arreola*, A Buehler, J Finlay, NN Lee, R Ermel Center for Comparative Medicine, City of Hope, Duarte, CA Conducting a study involving gut microbiota (GM) requires meticulous coordination between the researcher, husbandry, and veterinary technicians in order to be successful. Scientific curiosity in the GM has been increasing as it has shown to modulate immunologic and physiologic responses that determine underlying pathogenesis of several systemic diseases such as diabetes and colorectal cancer. The GM can shift with changes in experimental manipulations, husbandry practices, and veterinary interventions; thus, it is important to reduce variabilities introduced by often well-intended inadvertent changes. This abstract was created to better communicate husbandry and veterinary considerations when facilitating GM studies. Our study required several weekly food and/or water alterations to see GM changes, so it was important to have exceptional communication from all involved staff. Problems arose at the start of the study because husbandry staff was uncertain of what to do if emergencies like floods and low water levels were to be seen. To avoid miscommunication and introducing unintentional variabilities, details of the study and personnel involvement were relayed to all parties with several different forms of communication. We communicated with chow type stickers on the cage cards, marking water levels on bottles, cage cards indicating cage and water changes, and emails between management, husbandry, and veterinary staff. Lastly, the PI provided a summary of the study timeline which was shared with the research support staff. The active verbal and written communication between all parties allowed for a successful completion of the GM study while minimizing unintended experimental variabilities with positive feedback from the research support staff. It is important to keep husbandry factors consistent and this further highlights the importance of clear communications between all parties involved when conducting GM studies. PS4 Caught in the Middle: What Veterinary Residents Learn About Relationship-centered Care M Nowland*1, P Haidet3, TL Whitcomb2 Unit for Laboratory Animal Medicine, University of Michigan, Ann Arbor, MI; 2Comparative Medicine, Penn State Hershey College of Medicine, Hershey, PA; 3Department of Medicine, Division of Internal Medicine, Penn State College of Medicine, Hershey, PA 1

The practice of relationship-centered care (RCC), which emphasizes development of authentic partnerships between clients and veterinarians, is crucial both for the mental wellbeing of veterinarians and for client satisfaction. Mixed messages around this concept are common in undergraduate veterinary education, but the post-graduate environment has not been assessed. The purpose our qualitative study was to explore what messages about RCC residents are internalizing in laboratory animal medicine (LAM) training programs. We interviewed 24 residents from seven LAM training programs in the Eastern United States. Four themes and 3 sets of subthemes emerged from qualitative analysis of the de-identified interview transcripts. Themes included: 1) responsibility for maintaining relationships with researchers (building rapport, practicing clinical empathy, overcoming language barriers, communicating in the “authorized” way, and navigating e-mail limitations), 2) challenges with

professional identity (acting as the middleman between stakeholders, overcoming the stigma of the policing role, experiencing a lack of power to impact change), 3) operating within a culture of conditional value of veterinary knowledge, and 4) outlets for frustration (reliance on residency mates, limitations of venting). Our findings suggest that residents find themselves caught in the middle of an imperative to practice relationship-centered care, while at the same time balancing the conflicting demands of stakeholders and experiencing a lack of power to influence change, all within a culture in which their knowledge is frequently undervalued. These results have implications for the learning of RCC and provide an important background for refining curricula and creating effective support systems for residents. PS5 Replacing Analog Husbandry Room Logs with a Flexible Tablet-based Digital Solution TR Meier*, N Rindels, J Willhite Comparative Medicine, Mayo Clinic, Rochester, MN Animal research facilities are required to document a variety of animal husbandry activities. These activities are often documented on weekly or monthly room logs that are affiliated with a room or area. Room logs serve as a guidance document for staff as they outline what tasks need to be completed on a given day. Management uses room logs to document adherence to standard operating procedures and manage personnel performance. Our institution has multiple animal facilities in multiple buildings; every animal holding room has at least 1 or more room log. Manual review of paper-based logs is a time-consuming and inefficient way to monitor operations. At our institution, we leveraged our existing Filemaker application to create a completely self-supported and customizable digital method of tracking husbandry activities. The staff is assigned to rooms to support, species-specific tasks are then assigned to the rooms, and a dashboard outlines the tasks that are due, overdue, and completed for each room in the facility. Within the application, the animal care staff role is limited to task completion. The management role can complete tasks as well as create tasks and add, edit, or delete them from a given digital room log. The application was designed to operate without the ongoing need for a developer. Staff were issued tablets and provided 1 h of training on the system prior to converting to digital documentation. Feedback from animal care staff has been positive. They report feeling more confident that they have completed all of their work. In addition, management can review whether there are any overdue tasks in their facilities in less than a minute. Room Tasks also tracks cage changing volumes making it an important tool for monitoring weekly/daily changing volumes as a component of our staffing-to-workload and employee safety model. Overall, Room Tasks has simplified the documentation of activities for front-line staff, simplified monitoring staff performance for management, and provides a mineable database for metrics of interest. PS6 Comparison between Artificial Sentinels and Soiled Bedding Sentinel Mice to Refine the Health Surveillance Process AJ Osborne*1, CL Perkins2 Animal Resources Program, University of Alabama at Birmingham, Birmingham, AL; 2Laboratory Services, Charles River, Wilmington, MA 1

The 3Rs are guidelines for research that encourage the most humane and most scientifically relevant information simultaneously. Health surveillance of research colonies is necessary to ensure

108

an appropriate health status and to prevent a potential impact on research. However, traditional health surveillance with soiled bedding sentinel (SBS) mice often does not coincide with the 3Rs; at the end of a predetermined period, the mice are euthanized for sample collection. Furthermore, the literature documents that many infectious agents do not successfully transfer to SBS mice. To reduce animal use and improve the efficacy of health monitoring programs, many institutions are seeking to replace live mice with environmental testing or other artificial sentinel means. A pilot project was initiated to compare the effectiveness of artificial sentinel samples (flocked swabs or filter media) to a traditional SBS mouse. Our hypothesis is that the artificial sentinel sampling will be just as effective if not better than SBS samples for monitoring organisms of interest (specifically Helicobacter spp. and MNV). Soiled bedding from 2 rooms historically positive for MNV and Helicobacter spp. was split between a SBS mouse cage and an artificial sentinel cage at each weekly cage change. Once weekly a flocked swab was added to each artificial sentinel cage, and twice weekly these cages were manually agitated for 15 s. Media was exposed for the duration of the study. At the conclusion of the 12-wk experimental period, samples were collected including the flocked swabs, media filter, filter top cage lids, and fur swabs, oral swabs, and Opti-spot blood from the SBS mice. Artificial sentinel samples were more sensitive at detecting Klebsiella oxytoca, Rodentibacter spp. (R. heylii and R. pneumotropicus), Demodex genus, Helicobacter spp., and Tritrichomonas genus as compared to the SBS mouse samples. Artificial and SBS sentinel samples were equivalent at detecting MNV, Astrovirus, and Entamoeba genus. Overall, this pilot study shows that usingartificial sentinels for health surveillance is just as sensitive and even surpasses SBS mice, allowing opportunity for refinement in techniques and reduction of live animal use. PS7 Clopyralid Herbicide in Laboratory Animal Bedding and Feed Waste DM Kurtz*1, P Johnson2, W Steinmetz2, G Caviness1, P Poliachik3, D Gaffney1, RA Wiltshire1, K Laber1 Comparative Medicine Branch, National Institute of Environmental Health Science, Research Triangle Park, NC; 2Health & Safety Branch, NIEHS, RTP, NC; 3Facilities Operations Team, NIEHS, RTP, NC 1

A rodent-only facility housing approximately 19,000 cages was generating approximately 24,000 lbs. of non-hazardous, bedding and feed waste per month which was transported to the municipal landfill. As part of our effort to reduce landfill waste, we started to compost this waste. Within a short period of time, we received notification from the composting company that our waste contained unacceptable concentrations (> 5.0 ppb) of the herbicide Clopyralid. Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) is a selective herbicide for control of broadleaf weeds used extensively on food-producing crops, tree plantations, and residential lawns. In the early 2000s, many states started reporting problems from gardeners using compost on a variety of numerous plant species. Analysis found the compost contained Clopyralid, and certain plants were extremely sensitive. Since then, many states have issued pesticide advisories, and Clopyralid has since been banned for use on residential lawns. Clopyralid is relatively non-toxic to mammals with an acute, oral LD50 of > 5000 ppm. Previous testing of our standard, natural ingredient rodent feed by a commercial laboratory was negative for Clopyralid, and initial testing of our clean, unused bedding by the commercial lab (#2) recommended by the composting company was also negative. However, Clopyralid was detected by lab #2 in

PS8 Implications of Lab Mouse Trap Preference on Your Pest Control Program J Schoenberger*1, BJ Prendergast2, KR Luchins1, B Theriault1, G Langan1 Animal Resource Center, University of Chicago, Chicago, IL; 2Department of Psychology, University of Chicago, Chicago, IL 1

Insects are potential vectors of disease for laboratory animals. Therefore, implementing a pest control program is a requirement for animal research facilities. The Guide for the Care and Use of Laboratory Animals emphasizes the humane use of traps, however, insect traps commonly use glues that can inadvertently ensnare escaped laboratory mice, leading to distress and injury. This presents a challenge for research facilities attempting to identify insect populations within animal housing barriers. In an effort to improve use of pest traps in animal facilities, we sought to characterize behavioral interactions of lab mice with common insect and mouse traps. Three experiments using different combinations of traps (glue trap, live trap with a clear viewing window, and live trap with a red-tinted viewing window) and arenas addressed these questions. Mice were under direct video surveillance for all experiments and were immediately euthanized if captured via glue trap. Experiments 1 and 2 were performed within a smaller arena, whereas experiment 3 was performed in an animal housing room within an SPF barrier facility. Measures included exploration of the test environment, grooming behavior, time spent near each trap, and the latency to capture by traps of each type. Data to be presented indicate that lab mice were captured significantly more quickly by live traps than by glue traps, and were far more likely to enter a live trap as compared to a glue trap. In addition, mice did not appear to differentiate between clear or red-tinted window live traps. Taken together the results support the conclusion that a live trap combined with a glue trap provides the best approach to capturing escaped mice and insects within a single environment. PS9 Muzzle Swelling in a Nude Rat AL Carlson*, S Monette Memorial Sloan Kettering Cancer Center, New York, NY An 8-mo-old, female, intact athymic nude rat (Hsd:RH-Foxn1rnu) presented with an acute, right-sided, maxillary swelling of the muzzle. Four mo prior to presentation, the rat used as a model of Parkinson’s disease received a unilateral intracranial midbrain injection of 6-hydroxydopamine (6-OHDA) into the striatum. The rat was injected with D-amphetamine intraperitoneally 4 wk later to confirm depletion of dopamine and successful induction of the model. On physical examination, there was a poorly demarcated, firm, round, approximately 1 cm diameter swelling of the right maxillary region of the muzzle. The animal was bright, alert, responsive, able to eat and drink normally, and had a BCS of 3/5. Differential diagnoses included infectious, e.g., Staphylococcus aureus, and Rodentibacter spp., and neoplastic, e.g., squamous

cell carcinoma and osteosarcoma processes. Treatment with enrofloxacin 10 mg/kg PO q 24 h was initiated. After 1 mo of treatment, the swelling had increased in size, measuring 2.5 x 1.7 x 1.5 cm and encompassing the right lateral and dorsal aspect of the muzzle, necessitating euthanasia. The rat was submitted for a complete necropsy. At necropsy, the mass was noted to infiltrate soft tissue as well as bone. Histologically, the lesion consisted of nests of squamous epithelial cells with abundant keratinization, consistent with a squamous cell carcinoma, which invaded and effaced the nasal and maxillary bones and the nasal and oral mucosae. The neoplasm appeared to have originated from the oral mucosa due to the greater involvement of the oral tissues compared to the nasal mucosa, but a nasal origin could not be definitely ruled out. Naturally occurring oral squamous cell carcinomas have rarely been reported in rats and have not been previously reported in the athymic nude stock. Differential diagnoses for muzzle lesions in rodents, with a focus on infectious and neoplastic lesions, will be discussed.

During routine semiannual examination, a 10-y-old naive female rhesus macaque (Macaca mulatta) presented with 700 gm weight loss and an intestinal thickening in the right cranial abdomen detected by palpation. Differential diagnosis included gastrointestinal obstruction, neoplasia, abdominal granuloma, and inflammatory enteropathies. Radiographs revealed intestinal gas distention between L3-L5. Blood chemistry revealed elevated ALT and moderate hypoproteinemia. Hematology showed no abnormalities and fecal occult blood and TST were negative. No abnormalities of appetite or fecal production were noted prior to or following the exam. One wk later an additional loss of 600 gm was noted. The enlarged intestine palpated considerably longer (~15 cm). Radiographs confirmed intestinal enlargement, fecal stasis, gas accumulation, and no evidence of metastatic nodules in the thorax. Abdominal ultrasound confirmed previous findings and revealed an enlarged gall bladder. Follow-up ALT was normal but continued hypoproteinemia with significant hypoglobulinemia. Presumptive diagnosis (adenocarcinoma or obstruction) required surgical resolution, so a laparoscopic procedure was scheduled. Laparoscopy revealed a redundant colon with associated constipation involving the entire colon and distal ileum. Treatment involving laxatives (Senna glycoside) and fiber supplements was initiated, and oral metoclopramide was added later. After 7 d of treatment, fecal output increased considerably and treatment was discontinued. Commercial and natural fiber supplements (prunes) were continued to help normal GI motility. After 6 wk of treatment body weight and blood work returned to baseline levels, with no evidence of constipation noted. Redundant colon, or dolichocolon, is an anatomic abnormality involving the presence of colon redundancies affecting 1 or all 3 segments of the colon and flexures. The extra length forms additional loops, tortuosities, and kinks that predispose to constipation. The incidence in human population is unknown, and to the knowledge of the authors, this is the first case described in rhesus macaques.

Removal of feed pellets from dirty cages prior to dumping the bedding waste did not significantly reduce the Clopyralid concentrations. Clopyralid likely has no physiological effects on our laboratory rodents at the concentrations measured. However, these findings demonstrate another example of a chemical contaminant to which laboratory animals may be exposed and underscores the importance of monitoring for external sources of experimental variability.

PS12 Abdominal Distension in a Baboon (Papio anubis) DD Chen*, D Flanagan, DM Molk, J Morris Center for Comparative Medicine, Massachusetts General Hospital, Charlestown, MA A 5-y-old, 17.6 kg intact male olive baboon (Papio anubis) housed singly indoors underwent a heterotopic heart xenograft, upon which the animal recovered smoothly and unremarkably. Two d post-op, the animal presented acutely for lethargy, vomiting, and lying on the cage floor. The NHP was sedated for physical examination and diagnostics. On physical exam, the abdomen was distended, mucous membranes were a pale pink, and he had an sPO2 of 89-91%. All other vital parameters were unremarkable. Serum chemistry showed 2.5 times elevation of ALP; remaining bloodwork was unremarkable. Two-view radiographs revealed a moderate amount of free gas, as well as a stomach dilated with food content and air. A gastric tube was immediately introduced, and the stomach was decompressed. A large amount of ingesta and material was removed, however post-decompression radiographs showed pockets of free air remained in the abdomen. Differential diagnoses included ileus, GI partial or full obstruction, foreign body impaction, volvulus, or pyloric stenosis. With the unknown etiology of the distended abdomen and concern for reoccurrence, the decision to perform exploratory laparotomy was made. During assessment of the bowel, a small serosal injury to a focal area of the small intestine was discovered that narrowed the intestinal lumen, causing a partial obstruction. A small portion of the small intestine that was adjacent to the heart xenograft within the abdomen was likely injured during defibrillation of the heterotopic heart xenograft. As for treatment, the swollen focal area of the bowel was overstitched with a Lembert suture to improve lumen diameter. The rest of the GI was assessed, and no other abnormalities were noted. The animal recovered smoothly with the following post-operative management plan: maintenance LRS fluids, Ketorolac 2 mg/kg IV SID for 3 d, Cefepime 50 mg/kg IV SID for 7 d, buprenorphine 0.01 mg/kg IV for BID for 3 d, NPO for 2 dand slow return to a liquid diet and then solid food. After 1 wk, the baboon made a full recovery. PS13 Weight Loss, Intermittent Vaginal Bleeding and Pelvic Mass in a Hysterectomized Rhesus Macaque (Macaca mulatta) RA Lang1, S Achilles*1, ND Kock2, D Caudell2, M Cline2, M Leblanc1 ARP, Wake Forest University, Winston-Salem, NC; 2Pathology, Wake Forest School of Medicine, Winston-Salem, NC 1

A 13-y-old, 7.7 kg, female Rhesus macaque experimentally irradiated with 5 Gray total body irradiation 10 y prior was evaluated for weight loss, intermittent vaginal bleeding, and palpable pelvic mass. The animal had undergone supracervical total hysterectomy (TH) 5 y earlier for a suspicion of endometriosis and a prolonged history of dysmenorrhea, menorrhagia, and anemia during menses. Clinical signs resolved with TH but the origin of menorrhagia could not be determined based on uterine pathology. Two y later, a 6.5 x 4.8 x 4.3 cm intraabdominal mass was discovered on routine CT examination with no overt clinical signs. Cytology of a needle aspirate yielded lipids and brownish fluid and prompted a diagnosis of lipoma and persistent endometriosis. Clinical evolution of both conditions was closely monitored subsequently during regular physical examinations. Three y later, the animal presented a 20% body weight loss over a 3-mo period and started to show intermittent vaginal bleeding. CBC revealed normocytic anemia and abdominal ultrasound confirmed that the mass had not evolved. An exploratory laparotomy was

110

performed to evaluate the mass. A firm, pink, 7 x 6 x 5 cm mass at the pelvic inlet stemming from the TH stump was found. A dark colored cyst containing brown fluid was positioned cranial to the mass. A biopsy specimen was taken for histopathology and the animal recovered but was euthanized a few wk later for experimental reasons. A diagnosis of uterine leiomyoma stemming from the TH stump as well as abdominal and lung endometriosis were made based on gross necropsy, histopathology, and immunohistochemistry stains for estrogen and progesterone receptors on the lung lesions. Uterine leiomyoma and endometriosis are common estrogen-dependent reproductive pathologies in aging macaques and humans that may be hasten by aberrant estrogen signaling and local aromatase activity. TH with or without ovariectomy has been advocated for the management of severe cases in both conditions but several reports in the human and veterinary literature support that recurrence of leiomyoma from remnant uterine tissue as well as persistence of endometriosis may occur in both estrogen rich or poor environments even after surgery. PS14 Dyspneic Mature Ewe from an Animal Science Research Herd LA Taylor*, TH Vemulapalli Veterinary Pathobiology, Texas A&M Univeristy, College Station, TX A 4-y-old, 46 kg, Hampshire cross ewe presented for dyspnea. Three mo prior to presentation, the ewe had been acquired from the local sale barn for this research study. She had been naturally inseminated and was diagnosed open on rectal ultrasound. On initial examination the ewe was bright, alert, and in good body condition with an elevated respiratory rate and temperature. Auscultation revealed increased bronchial-alveolar sounds and an inspiratory stridor. She was initially treated symptomatically with florfenicol and banamine. One wk later the ewe’s condition had deteriorated. She was euthanized and submitted for a full necropsy. On necropsy the mucous membranes were diffusely pale. The abomasum contained a moderate load of Haemonchus contortus. Multiple abscesses in the right kidney were noted, with 90% of the parenchyma occupied. Approximately 40% of the diaphragm was adhered to the liver and multiple 0.7-6 cm, pale tan, round, and firm nodules were noted. The space surrounding the liver had several abscesses, up to 5 cm, that were displacing the duodenum. A 10 x 6 x 5 cm abscess was adhered to the liver, ventral ruminal wall, and sternum. The thoracic cavity revealed multiple enlarged, abscessed lymph nodes with multifocal mineralization. Multiple raised, firm, multifocal nodules (2.5-4 cm), were noted within the pulmonary parenchyma, the lungs failed to collapse, and the pleura was firmly adhered to the ribs. A 4 x 2.5 x 2 cm friable mass originating in the ethmoid mucosa and bilaterally effacing the ethmoid turbinates was found in the skull. Histopathology on the nasal tumor was consistent with Enzootic Nasal Tumor Virus-1, the lung histopathology was suggestive of Maedi-Visna virus, and bacterial culture confirmed Corynebacterium pseudotuberculosis, the causative agent of caseous lymphadenitis. Source of research animals should be carefully considered prior to purchase.

An 11-y-old, 9.0-kg, male, rhesus macaque (Macaca mulatta), in an indoor facility with a history of inappetence and weight loss (1.7 kg over 5 wk) presented with an acute onset of generalized seizures. This macaque was used in neuroscience research and had 1 right cephalic recording chamber in place. The macaque was sedated with ketamine (5 mg/kg), dexmedetomidine (250 mg/m2), and midazolam (0.1 mg/kg). Physical exam revealed thin body condition (2/5). Complete blood count revealed a leukocytosis (19.7 K/mL, reference range (RR) 4.5-19.5 K/mL) characterized by neutrophilia (18 K/mL, RR 0.7-12.7 K/mL). Serum chemistry was unremarkable. Differentials included meningitis, encephalitis, sepsis, and neoplasia. Fluids (200 mL of LRS) were administered subcutaneously. A loading dose of ceftriaxone (100 mg/kg, IM) was administered and continued once daily at 50 mg/kg. The following day, the macaque was chaired for chamber cleaning and a culture acquired from the chamber revealed ceftriaxone susceptible Corynebacterium sp. Corynebacterium spp. are frequent contaminants of cephalic implants in nonhuman primates. Six d following the initial presentation the macaque was sedated for an MRI. Brain MR imaging revealed a ring-enhancing focal lesion adjacent to, and possibly connecting with, the head chamber and calvarium defects surrounding the chamber, suggesting a brain abscess. Follow-up bloodwork revealed resolution of the leukocytosis (8.1 K/mL) and neutrophilia (5.4 K/mL). The macaque underwent an explant surgery 3 wk after initial presentation. An MRI conducted 1 mo following explantation revealed a 69% reduction in volume. The reduction in volume of 10.6% per week assessed by MRI is similar to that observed in humans following antibiotic therapy. Brain abscessation is a potential sequela of chronic implants utilized in neuroscience. In addition to appropriate antibiotic therapy, explantation of the chamber should be considered to hasten the resolution and advanced imaging techniques, such as MRI, are instrumental in assessing therapeutic efficacy. PS16 Necrosis of Distal Extremities in an Owl Monkey (Aotus nancymaae) AM Braxton*, J Izzi Molecular and Comparative Pathobiology, Johns Hopkins University, Baltimore, MD A 12-y-old, female owl monkey (Aotus nancymaae) presented for nonweight bearing lameness of the right leg 2 d after undergoing a protocol-driven splenectomy. On exam, severe soft tissue swelling and erythema affected the leg distal to the knee and ulceration was noted on the plantar surface of the metatarsus and phalanges. The animal was unable to grasp with the affected foot and lacked a withdrawal reflex. Differential diagnoses included traumatic bone fracture, soft tissue injury, and ischemia-reperfusion injury. Radiographs were performed and fracture was ruled out. Following debridement of necrotic tissue, the wound was

managed with daily iodine baths, passive range of motion therapy, bandage changes and analgesics. Seven d post-presentation, granulation tissue began to form on the plantar surface of the tarsus but the animal remained nonweight bearing. During this treatment course, an ulcerated lesion developed on the dorsal aspect of the tail that ultimately became necrotic and required amputation of the distal tail. Despite aggressive management, tissue necrosis progressed and function was never regained. Approximately 1 mo post-presentation, the animal was anesthetized for further surgical debridement. Examination of the tissue revealed bone exposure of the lateral and plantar surface of the fourth metatarsal bone with minimal viable surrounding tissue. Euthanasia was elected at this time due to poor prognosis. Necropsy of the limb revealed epidermal ulceration, inflammation, and necrosis. Histopathology of the tail tip revealed diffuse coagulative necrosis and intravascular thrombi. No thrombi were identified within the limb or major vessels, however, the history of splenectomy and clinical presentation combined with clot formation in the tail led us to suspect a hypercoagulable state was present. Hypercoagulability is well reported in humans following splenectomy. Though owl monkeys are commonly splenectomized for malaria research, there are no published reports of hypercoagulability following splenectomy in this or other nonhuman primate species. Based on the clinical and histopathology findings, a diagnosis of microthrombosis leading to distal tail necrosis secondary to a hypercoagulable state following splenectomy was reached. PS17 Auricular Swelling and Discharge in a Male Mouse LF Mosca*, J Klug, JM Snyder Department of Comparative Medicine, University of Washington, Seattle, WA An experimentally naïve 28-mo-old male mouse presented for dermatitis and alopecia on the right shoulder, extending up through the lateral cervical region. Two mo prior, the mouse had experienced mild dermatitis on the intrascapular and dorsal cervical area. The previously observed dermatitis was treated with weekly toe nail trims, and resolved within 3 wk. On physical examination the newly developed dermatitis was an approximately 2-centimeter long lesion spanning the lateral right shoulder and right lateral cervical region. Another discrete, alopecic 0.5 cm x 0.5 cm lesion was also present at the base of the right ear. The mouse was given a toe nail trim, however, within 5 d the lesions had not improved. Moderate thickening and swelling of the right ear base was noted, and the ear canal was producing a serous, clear to pink-tinged discharge. Cytology of the discharged showed scattered diplococci, proteinaceous material, and red blood cells. The differential diagnosis list included otitis media and/or externa, trauma, tooth root abscess, or neoplasia. The mouse did not exhibit signs of difficulty eating or weight loss. The mouse was initiated on topical antibiotic therapy to the ear canal once daily. Within one week the swelling at the ear base was undetectable, however, serous,watery discharge was still noted in the ear canal. Cytology of the discharge showed occasional plasma cells. Four d later, a 1 millimeter portion of exposed cartilage was noted on the right ear base, surrounded by mildly erythemic skin. Due to this development euthanasia was elected. Necropsy confirmed moderate otitis of the right ear with dermatitis and ulceration. On histologic examination a densely cellular neoplasm with local invasion into the middle ear and destruction of surrounding skeletal muscle and bone was encountered, with metastasis to the lungs. The neoplasm arose from the Zymbal’s gland, a multilobulated sebaceous holocrine gland located anterior-ventral to the ear canal in rats and mice.

Neoplasms reported from the Zymbal’s gland are rare, but more commonly reported in rats and include sebaceous cell adenoma, squamous cell papilloma, and carcinoma of sebaceous and/or ductal epithelial origin. PS18 Emphysematous Facial Lesion in a Musk Shrew (Suncus murinus) N Fogarty*, R Duran-Struuck, A Brice, T Manzi University Laboratory Animal Resources (ULAR), University of Pennsylvania, Philadelphia, PA An adult male musk shrew (Suncus murinus) originating from a breeding colony and used experimentally for emesis studies was reported for a lesion on the right side of the face during routine health examinations. Ventrolateral to the right orbit, a soft, round swelling approximately 1.0 cm in diameter was observed. The animal was otherwise active with appropriate body condition and hydration. Examination under general anesthesia did not identify an oral lesion, and surgical lancing of the swelling resulted in its deflation without hemorrhage or purulent discharge. A short course of Meloxicam (5 mg/kg PO SID for 3 d) was administered following the lancing. Over the next 2 mo, this emphysematous mass increased and decreased in size in correspondence with respiration, however the animal continued to thrive. The animal was removed from the experiment following the onset of the lesion, but continued to be used for breeding purposes. Computed tomography and magnetic resonance images of the skull did not reveal any abnormalities that might contribute to the development of emphysema, such as an oral or nasal fistula. As the lesion failed to spontaneously resolve, the animal was euthanized and submitted for postmortem examination. The cause of the lesion was not apparent on gross examination. Microscopically, the subcutaneous tissue was markedly distended by clear space lined by abundant epithelioid macrophages and multinucleated giant cells with fewer lymphocytes. The surrounding subcutaneous connective tissue and muscle fibers were separated by abundant clear space. Based on these findings, the lesion was diagnosed as focal subcutaneous facial emphysema (SFE). There are several documented causes of SFE in humans, such as orofacial trauma, iatrogenic injury (i.e. from dental or surgical procedures), infections (i.e. retropharyngeal abscessation), and pneumomediastinum. This case highlights a unique lesion in an increasingly popular species in the laboratory animal field.

Nineteen 3-4 month old female NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG) mice presented with acute unilateral or bilateral hind limb paresis or paralysis. Upon examination, mice demonstrated a range of maintained deep pain sensation with limited withdrawal reflex to a complete absence of both. These mice also had mild dehydration and poor to thin body condition with a range of BCS from 1-2.5. The mice were from a cohort (n = 30) implanted with a human patient derived breast cancer xenograft (PDX) that was in its fourth passage. The tumor was implanted in the mammary fat pad 1 mo prior to the clinically observed onset of

112

paresis/paralysis. The mice were housed in a SPF facility designed specifically for immunodeficient strains. Based on clinical signs and history, differential diagnoses included mouse hepatitis virus (MHV), Theiler’s murine encephalomyelitis (TMEV), lactate dehydrogenase elevating virus (LDEV), and polyomavirus. Necropsies performed on affected mice (n = 10) were unremarkable with no significant gross lesions. On histopathologic examination, bilaterally within the ventral funiculi and nerve roots of the lumbar spinal cord, there was variable axonal swelling and vacuolation of myelin sheaths. Similar lesions were observed in the corresponding sciatic nerves of affected mice. Fresh PDX samples (n = 6) from affected mice obtained at the time of necropsy were submitted for a broad rodent infectious PCR panel which included the agents in the differential diagnosis list. All samples were PCR positive for LDEV, as were pooled plenum swabs from the rack on which these animals were housed. LDEV is known to cause serum elevation of the LDH enzyme, but also causes degenerative myelopathy and neuropathy in certain strains of mice, especially immunodeficient strains. LDEV may be transmitted within colonies by infected mice, or experimentally secondary to contamination of cell lines or xenografts, which represents an important source of spread.

A 10-y-old, pair-housed female common marmoset (Callithrix jacchus) presented with a firm, moveable, abdominal mass and hepatomegaly on routine semiannual physical examination. Significant clinical pathology findings included anemia; azotemia; and elevated levels of gamma-glutamyl transferase, lipase, and amylase. An abdominal ultrasound revealed a cranioventral mass (3.0-4.0 cm in diameter) and chronic changes to both kidneys. The differential list included neoplasia, pancreatitis, and hepatobiliary disease. One mo after initial evaluation, the marmoset was euthanized due to increased abdominal mass size, along with progressive weight loss and lethargy. On necropsy, all liver lobes contained multiple pale-tan to white, semi-firm masses (0.1-2.0 cm in diameter) with central necrotic areas and hemorrhage. There was an additional large, oval, mesenteric mass (5.0 x 4.0 x 3.5 cm) replacing the pancreas adjacent to the superior duodenum. On histopathology, hepatic lobules were multifocally effaced and compressed by numerous well-demarcated, non-encapsulated, densely cellular masses that often infiltrated portal tracts. The hepatic and mesenteric masses were composed of deeply basophilic neoplastic polygonal and pyramidal cells forming lobules and trabeculae, supported by a fibrovascular stroma. Neoplastic cells often formed palisades around primitive ducts containing a brightly eosinophilic matrix. Neoplastic cells were closely packed with poorly defined borders and small amounts of basophilic granular cytoplasm. Anisocytosis and anisokaryosis were moderate with high mitotic activity. Neoplastic cells exhibited cytoplasmic and nuclear immunoreactivity to beta-catenin (a marker involved in cellular development), and were negative for epithelial (pancytokeratin), mesenchymal (vimentin), neuroendocrine (chromogranin A, synapthophysin), and neuronal markers (synapthophysin). Based on histomorphology and immunohistochemical features, the hepatic masses were diagnosed as poorly

Hypoplastic left heart syndrome (HLHS) is a complex congenital heart disease that requires multiple surgeries for any chance at survival. These surgeries result in a right heart that pumps blood to the systemic circulation with passive flow through the pulmonary circulation. Right ventricular dysfunction is a common morbidity in these patients, and cell-based therapy is a promising strategy to support ventricular function and delay or prevent the need for cardiac transplantation. The aims of this pilot study were to 1) develop a nonhuman primate model of right ventricular pressure overload, and 2) demonstrate engraftment of hiPSC-CL cells in the compromised heart. Nine rhesus macaques (Macaca mulatta) underwent pulmonary artery banding (PAB) surgery and cardiac event recorder implantation. Approximately 2 wk later, hiPSC-CL cells were injected into the right ventricular myocardium of four immunosuppressed animals. Animals were followed for 4 or 8 wk with periodic analyses of hematology and serum chemistry markers, along with performing echocardiograms prior to and subsequent of PAB. Histological analysis of all tissues was performed, including the entire heart (4 mm slices), and the cardiac tissue was stained against human cardiac troponin (hCTnI). Three animals did not complete the study due to intraoperative (n = 1) or post-operative (n = 2; first 2 animals) complications. Adjustments were made to the surgical procedure after the first 2 animals, and subsequent animals tolerated the PAB procedure well. All animals developed varying degrees of pathology evident on echocardiogram and histology consistent with right ventricular pressure overload. No significant arrhythmia events occurred in any of the 6 animals. All 4 animals administered hiPSC-CL cells exhibited significant engraftment at 4 and 8 wk. This study is the first to describe a PAB model of right ventricular pressure overload in the nonhuman primate, and is also the first to report engraftment of human iPSC-derived cardiac lineage cells in non-infarcted primate myocardium. PS21 Reducing Inter-operator Variability Using a Novel 3D and Thermal Measurement System when Measuring Subcutaneous Tumours in Mice J Steed* Marketing , Fuel3D, Oxford, , United Kingdom The key to successfully assessing therapeutic efficacy and accurately calculating tumour growth inhibition is ensuring that each group within a study has the volumes consistently measured across the life of the experiment by any operator. A previously published investigation showed a statistically significant reduction in inter-operator variability observed across 3 in vivo efficacy studies conducted by multiple users when using a novel 3D and

thermal imaging system. We now explore how this reduction in inter-operator variability can be seen across a much larger dataset. Our dataset includes 5,677 scans and 4,743 corresponding calliper measures collected in 26 laboratories across 276 studies with 117 users, 34 mouse strains, and 120 cell lines. Scans were conducted by holding the mouse up to the system and automatically capturing red/green/blue (RGB), thermal, and 3D images of the mouse and tumor body. This process took less handling time than recording length and width with callipers. Once captured, the system then automatically processes this data to segment, record, and generate volume information for each scan. After analysing the variability of the 2 methods using coefficient of variation (CoV), intra class correlation (ICC) subset analysis, and significance testing, we can see that the 3D and thermal imaging system produced a median CoV of 0.176 compared to a median calliper CoV of 0.197. Significance testing produced a P value of 0.01794 indicating that this is a statistically significant result, further backed up by the ICC subset analysis. We conclude that introducing a novel 3D and thermal imaging system to a subcutaneous tumour volume collection methodology can offer a significant improvement in inter-operator variability and help to improve study reproducibility across a wide range of studies, mouse strains, and cell lines.

Metabolic syndrome has been associated with development of diabetes and heart failure. Although the pathogenesis of heart failure with preserved ejection fraction (HFpEF) is not clearly understood, many reports suggest that metabolic dysfunction and hypertension are comorbidities, which are the major underlying mechanisms for HFpEF. Thus, animal models that show robust metabolic dysfunction in the absence of high-fat diet feeding or genetic mutation are invaluable tools for understanding the pathogenesis of HFpEF as well as advancing therapeutic drug development. Recently developed MSNASH model, resulting from a cross between the AKR/J and C57BL/6J (B6/J) mouse strains, spontaneously develops robust metabolic syndromes in the absence of high-fat feeding, with intact leptin pathway. However, the cardiac systolic and diastolic phenotype of the MSNASH mouse has not been evaluated. We hypothesized that metabolic dysfunction in the MSNASH model induces progressive development of HFpEF. Systolic and diastolic functional phenotype of male MSNASH and B6/J (control) mice were evaluated using echocardiography at 11, 19, 24 and 33 wk of age, and the metabolic phenotype was evaluated at 12 and 25 wk of age. Echocardiography and contrast enhanced ultrasound (CEUS) imaging was performed under isoflurane (1 to 3%) anesthesia. MSNASH mice showed obesity (32% higher body weight), hyperinsulinemia (1321% higher), hyperglycemia (41.7% higher), glucose intolerance and insulin resistance (ipGTT AUC ~55 % higher) compared to control B6/J as early as 12 wk old. Further, MSNASH mice displayed preserved systolic function (ejection fraction 69.1 ± 2.7% in MSNASH vs 73.7 ± 1.6 % in B6 control at 33 wk old) with progressive increase in left ventricular (LV) mass ( 146.9 ± 4.8 mg at 11 wk old vs 234.6 ± 13.1 mg at 33 wk) and LV posterior wall thickness at diastole (LVPWD) (0.90 ± 0.04 at 11 wk vs 1.16 ± 0.08 at 33 wk) and decrease in radial diastolic strain rate (-14.05 Pk(1/s) in MSNASH vs -19.83 Pk(1/s) in control B6 at 33 wk old), a measure of diastolic dysfunction from 11 to 33 wk of age compared to age matched B6/J mice (LV mass 102.4 ± 3.2 mg at 11

Notably, oxygen consumption at peak exercise capacity was significantly reduced in MSNASH mice (35.1 % less peak VO2 consumption) compared to control mice at 30 wk of age. Furthermore, poor skeletal muscle vascular perfusion (CEUS time to peak readout 44.82 ± 3.09 s) was observed in MSNASH mice compared to control B6/J (CEUS time to peak 18.95 ± 4.45 s) mice at 34 wk of age. Results indicate that MSNASH mice show development of a progressive HFpEF phenotype in conjunction with metabolic syndrome. PS23 The Influence of Animal Facility Lighting on Growth of Human Breast Cancer Xenografts in Nude Mice RT Dauchy*, DE Blask, S Xiang, M Anbalagan, SM Hill Laboratory of Chrono-Neuroendocrine Oncology, Tulane University, New Orleans, LA Animal facility light exposure influences temporal coordination of circadian rhythms of normal and neoplastic tissues in laboratory animals in an intensity-, wavelength-, and duration-dependent manner. Recent evidence indicates that rotating night shift workers have an increased risk of developing breast and prostate cancers, which has been directly associated with light at night (LAN) as the principal risk factor. Little is known, however, regarding exposure to blue-enriched (460-480 nm) light-emitting diode (LED) light at daytime (bLAD), the most rapidly emerging lighting technology globally. Our previous studies demonstrated that exposure of human prostate tumor-bearing nude rats to bLAD amplified production of the nighttime circadian neurohormone melatonin resulting in decreased tumor growth and metabolism. In this GLAS-supported study we tested whether dim-LAN (dLAN) stimulates, while the bLAD-enhanced nocturnal melatonin signal suppresses, human breast tumor growth. Athymic female nude mice (Crl:NU(NCr)-Foxn1nu; 4-5 wk-old) under an IACUC-approved protocol were maintained in an AAALAC-accredited facility for 8 wk on 1 of 3 lighting regimens: Group I, 12L cool white fluorescent (CWF, control):12D (0 lux); Group II, 12L(CWF):12dLAN (0.02 lux); and Group III, 12bLAD:12D (0 lux). All groups (n = 10/group) were maintained in a common light phase (lights on 0600h) lighting photoperiod (83.36 ± 2.64 lux, within cage). Following two weeks light exposure all mice were inoculated subcutaneously with MCF-7 human breast cancer cells (3 x 106 cells) and measured for tumor growth. Latency-to-onset of tumor growth (first palpable mass) and tumor growth rates were significantly faster in II (dLAN), and slower in III (bLAD), compared to I (control) mice (P > 0.001). Peak nighttime (2400 h) plasma melatonin levels (mean ± 1 SD) for groups I – III were significantly different at 140.2 ± 7.9 pg/mL, 16.5 ± 3.1 pg/mL, and 934.6 ± 27.5 pg/mL, respectively. Final harvest tumor weights for groups I-III were, 0.84 ± 0.08 g (d 38), 1.04 ± 0.02 g (d 27), and 0.36 ± 0.10 g (d 50), respectively. These findings show that animal facility dLAN stimulates, while bLAD-amplified nocturnal melatonin levels inhibit, growth activity in MCF-7 human breast cancer in vivo.

PS24 Inhibition of Human Cancer Growth in Nude Rats by Dietary Melatonin and Omega-3 Fatty Acids RT Dauchy*1, EM Dauchy2, DE Blask1 Laboratory of Chron-Neuroendocrine Oncology, Tulane University, New Orleans, LA; 2Medicine, Louisiana State Health Sciences Center, New Orleans, LA 1

Melatonin (MLT), produced by the pineal gland in mammals primarily at night, and omega-3 fatty acids (FAs) regulate linoleic acid (LA)-dependent metabolism and growth in rodent and human tumors in vivo. These agents inhibit LA-uptake and conversion to the mitogenic agent 13-hydroxyoctadecadienoic acid (13-HODE). Previous studies showed that proliferative, signal transduction and LA metabolic activity were abrogated in tissue-isolated human PC3 prostate and FaDu hypopharyngeal squamous cell xenografts perfused in situ in nude rats with donor blood replete with MLT (1nM) or eicosapentaenoic acid (0.4 mM). In this IACUC-approved study, human PC3 and FaDu xenografts were grown in male nude rats (Hsd:RH-Foxn1rnu) maintained on a 5% corn oil (CO) diet for a period of 4 wk. PC3 and FaDu tumor latency-to-onset (first palpable mass) and growth rates were, respectively, 18 and 26 d, and 0.60 ± 0.04 and 0.48 ± 0.06 g/day (n = 8/group). When estimated tumor weights were 3.5 g, tumor-bearing animals were divided into 2 groups (n = 4). Control tumor-bearing rats were maintained on the 5% CO diet, while experimental groups were placed on a combination test diet consisting of MLT (50 mg/d)/5% fish oil (FO). Control group tumors continued to grow as before, while those in the test diet groups regressed at a rate of 0.27 ± 0.03 (PC3) and 0.19 ± 0.01 g/ day (FaDu), respectively. Final mean tumor weights of controls were 6.65 ± 0.56 g (PC3) and 5.90 ± 0.28 g (FaDu), while those of test diet rats were 2.38 ± 0.18 g (PC3) and 2.25 ± 0.16 g (FaDu). Prior to complete tumor regression in test groups, tumors were prepared for arteriovenous blood measurements. LA uptake and 13-HODE release by PC3 and FaDu tumors in control animals were, respectively, 3.1 ± 0.9 and 3.6 ± 0.7 µg/min/g (LA), and 21.3 ± 1.9 and 18.8 ± 0.9 ng/min/g (13-HODE), and was completely suppressed in tumors of test diet rats. PC3 and FaDu tumors in test diet animals exhibited a reduction of over 65% in tumor cAMP levels, compared to controls. Results indicate that a combination of decreased dietary LA and increased dietary MLT and omega-3 FAs elicit a strong growth inhibitory effect on these two human tumors, and may encourage efforts to reduce LA and increase omega-3 and MLT consumption. PS25 Fully Automated Mouse Echocardiography Analysis Using Deep Convolutional Neural Networks C Duan*, M Montgomery, DK Hirenallur-Shanthappa Pfizer INC, Cambridge, MA Echocardiography (echo) is a translationally relevant ultrasound imaging modality widely used to assess cardiac structure and function in preclinical models of heart failure during drug development. Though echo is a valuable tool for quantifying endpoints, the image analysis is a time consuming, resource demanding process, and susceptible to inter-reader variability. Recent advancements in machine/deep learning have enabled researchers to automate image processing and analysis and reduce analysis time and inter-reader variability in the field of medical imaging as well as in preclinical research. We propose to utilize deep learning to develop and validate an automation tool for the analysis of parasternal long axis brightness (B)mode and (M)-mode echo images of mouse.

PS26 Fat Imaging: A Refined Micro-CT Approach S Ullas*1, M Montgomery1, B Faherty2, T Ross2, DK Hirenallur-Shanthappa1 Comparative Medicine, Pfizer INC, Cambridge, MA; 2Pfizer, Cambridge, MA 1

Assessment of fat distribution is essential to understanding the pathophysiology of obesity and obesity-associated disorders and the development of therapies against these disorders. Magnetic resonance imaging (MRI) and computed tomography (CT) have the ability to provide quantitative information on fat distribution in different compartments of the body. However, both these tools have low throughput. We evaluated a refined, high throughput micro-CT imaging technique in conjunction with an automated image analysis tool to assess fat distribution in diet-induced obesity (DIO) mouse model. In addition to control and DIO groups (18 to 20 wk old), a DIO plus Liraglutide treatment (0.3 mg/kg, subcutaneous, once daily for 10 d), was included to validate a refined micro-CT imaging technique. Liraglutide is a glucagon like peptide-1 (GLP-1) receptor shown to induce weight loss clinically, when administered subcutaneously. Each group consisted of 10 mice, for a total of 30. Animals were anesthetized using isoflurane (1 to 3%), and underwent micro-CT imaging of whole body and abdominal region between lumber vertebra 1 to 4, and whole body dual X-ray absorptiometry (DEXA) imaging. Data from micro-CT was then compared with outputs from Echo-MR (echo-magnetic resonance), DEXA and excised visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) using 1-way ANOVA with post hoc Turkey test and Pearson’s correlation coefficient analysis. Results of total fat from micro-CT (5704 ± 278 mm3 in DIO vs 1776 ± 232 mm3 in control), DEXA (19.74 ± 0.9 g in DIO vs 7.7 ± 0.66 g in control) and ECHO-MR (18.47 ± 1.23 g in DIO vs 4.24 ± 0.70 g in control) showed significantly higher fat content in DIO mice compared to control group, and the liraglutide-treated group showed significantly lower total body fat in DIO mice (micro-CT total fat: 3862 ± 425.7 mm3; DEXA 14.69 ± 0.92 g) compared to untreated DIO (micro-CT total fat: 5704 ± 278 mm3 ; DEXA 19.74 ± 0.9 g). Total whole body and abdominal fat, and SAT values from the micro-CT imaging correlated well (Pearson’s ‘r’ coefficient values > 0.80) with excised total body fat and SAT values. However, the VAT values from micro-CT didn’t correlate well (Pearson’s ‘r’ coefficient values < 0.50) with excised VAT. The micro-CT, DEXA imaging and echo MR readouts of total fat, VAT and SAT values correlated well with one another with Pearson coefficient ‘r’ value > 0.94. Importantly, refinement to mi-

cro-CT imaging technique and use of automated image analysis reduced image acquisition and analysis time by 50 %. Our results suggest that a refined micro-CT imaging technique with automated analysis can be used to assess total and subcutaneous adipose tissue in preclinical models of obesity in a high throughput manner. PS27 Reproductive Factor Influences Spontaneous Tumors in FVB/N Mice Q Zhang1, C Leung1,2, L Gerweck1, P Huang*1 Radiation Oncology, Massachusetts General Hospital & Harvard Medical School, Boston, MA; 2Division of Urology, Department of Surgery, Prince of Wales Hospital, The Chinese University of Hong Kong, Shatin, China 1

The FVB/N strain of mice is widely used in cancer research, including the development of transgenic mouse models. Previous studies have reported the development of spontaneous tumors as a function of mouse age, gender, and the presence or absence of specific genes. However, little is known about the influence of reproductive factors on the spectrum and incidence of spontaneous tumors. Our aim was to record the spontaneous tumors in our retired breeders and naïve nonbreeding FVB/N mice, and analyze the relationship between tumor incidence, reproduction, and histopathologic tumor type. A total of 843 mice (507 retired breeders and 336 nonbreeding mice) were observed during their natural lifespans (average ages of 724±139 and 731±229 d, respectively). A complete necropsy was performed on all mice that died during the study, on those euthanized when they were sick or developed tumors. All grossly observed lesions were collected for histopathologic study. The overall incidence of spontaneous tumors was 56.0% (284/507) in breeders and 50.0% (168/336) in nonbreeding mice (P = 0.086). The tumor incidence was 57.3% (102/178) and 55.3% (182/329) in male and female breeders; and 45.7% (43/94) and 51.7% (125/242) in male and female nonbreeding (all P > 0.05). Histopathologic findings showed that the most common neoplasm in both male and female breeders was lung alveolar-bronchiolar tumor (43.3% and 22.8%), as well as in nonbreeding FVB/N mice (38.3% and 21.5%). In female retired breeders, the second most common was mammary gland tumor (14.6% incidence); but only 0.4% incidence was detected in female nonbreeding mice (P < 0.0001). There was a higher tumor incidence of histiocytic sarcoma (10.7%) in female nonbreeding mice compared to a 3.6% incidence in retired female breeders (P = 0.001). The reproductive factor did not affect the overall incidence of spontaneous tumors in our FVB/N mice but significantly increased the risk of mammary tumor in female breeders and protected them from developing histiocytic sarcoma. The tumorigenesis profile shift with age, gender, and reproduction should be carefully considered when using FVB/N and FVB background transgenic mice in cancer research.

B-mode, and to segment the LV anterior wall and posterior wall in M-mode images. The neural networks were trained and tested using manually segmented B-mode and M-mode images. The segmented images were then further processed to automatically identify the diastole and systole phases of the heart cycle, and to compute cardiac structural and functional metrics. Bland-Altman analysis, Pearson’s correlation, and Dice Similarity Coefficient (DSC) were used to evaluate the performance of the proposed deep learning-based echo analysis pipeline. The neural networks achieved high DSC (0.92 to 0.96) in the segmentations, and excellent correlations (r = 0.85 to 0.99) between automated analysis and manual analysis outputs. Bland-Altman analysis also showed excellent agreements between the automated analysis and the manual analysis. The use of this automated analysis tool reduced manual analysis time by 90%. In conclusion, we developed an automated echocardiography image analysis pipeline based on deep learning. This tool allows for fast and accurate analysis of B-mode and M-mode mouse echo data and mitigates the issue of inter-reader variability in manual analysis.

Small animal models are vital for investigating SARS-CoV-2 (SCV2) pathogenesis and potential COVID-19 treatment options. While hamsters remain the leading small animal model of SCV2 infection, laboratory mice present certain advantages such as genetic manipulation. Here, we investigated the use of a mouse-adapted SCV2 (maSCV2) capable of infecting mice that do not carry the

human angiotensin 1 converting enzyme 2 (ACE2) receptor used by SCV2 for cellular entry. We hypothesized that infected mice would develop clinical disease (ex. weight loss) and would have histopathologic findings similar to those observed in human patients and other SCV2-infection animal models. Three groups of mice (6 C57BL/6J males, 6 C57BL/6J females, and 4 As:129S1 females) were inoculated with maSCV2 intranasally (50 ul/nare of infectious dose) under ketamine/xylazine sedation. These mice were then weighed and monitored daily until euthanasia on d 5 post infection. Two mice were euthanized at d 3-4 post infection because of severe clinical signs, including absence of escape response, hunched posture, squinting, increased respiratory rate, and rough hair coat. Percent body weight loss was examined by t-test and ANOVA at P < 0.05 and revealed that mice lost a significant percent of body weight. Male C57BL/6J mice lost significantly more weight (5.8 ± 2.5%) than the female C57BL/6J mice (1.2 ± 2.6%), and female As:129S1 mice lost significantly more weight (12.2 ± 3.5%) than female C57BL/6J mice. Histology revealed mild to moderate inflammatory changes, with the As:129S1 mice exhibiting more prominent peribronchiolar mononuclear inflammation. In conclusion, we demonstrated that maSCV2 infection produced clinical signs and pathology in wild-type C57BL/6J and As:129S1 mice. The development of this animal model presents a wide array of possibilities for COVID-19 researchers, especially to those wanting to use genetically modified mice. Future studies include evaluation of maSCV2 infection in outbred and inbred mice, including transgenic mice. PS29 Effects of Buprenorphine Treatment on Influenza Pathogenesis in Ferret (Mustela putorius) Models V Mrotz*1, J Belser2 Comparative Medicine Branch, Centers for Disease Control and Prevention, Jackson, GA; 2National Center for Immunization and Respiratory Diseases, Centers for Disease Control and Prevention, Atlanta, GA 1

Ferrets represent the gold standard model for influenza A virus (IAV) research due to their natural susceptibility to human and zoonotic IAV, comparable respiratory anatomy and physiology to humans, and development of clinical symptoms similar to those seen in infected humans. As presence and progression of clinical symptoms can be useful in infectious disease research, uncertainty of how analgesics may perturb research outcomes and comparable characteristics of disease progression have outweighed the concern of discomfort related to these symptoms. Nonetheless, 3Rs drive researchers to consider how this invaluable model for IAV research can be refined. Opioids offer a possible refinement option that would not directly impact the inflammatory cascade involved in IAV infection. Mirroring pathogenicity studies that utilize ferrets, we intranasally inoculated 12 ferrets (castrated male, 9-mo-old) with the H3N2 IAV A/ Panama/2007/1999 and divided them into 3 treatment groups (n = 4) where 2 groups received buprenorphine (Bup) treatments on 2 different schedules based on historical peaks of clinical signs (0.04 mg/kg Bup SC BID, Group 1 d 0-4 post inoculation (p.i.) and Group 2 d 5-9 p.i.) and the third group received saline treatments corresponding to those schedules. Duration and location of viral replication, lymphohematopoietic changes, and clinical symptoms were comparable across all groups at all timepoints. High quantities of infectious virus in nasal wash specimens were detected in ferrets from all groups through d 5 p.i., indicating that Bup treatments on either schedule did not substantially alter replication kinetics in the upper respiratory tract. Ferrets receiving Bup treatments exhibited transient increases in weight loss

and fever compared to the saline group, but all groups ultimately achieved similar peaks in both measurements. Collectively, these findings support the continued evaluation of Bup as a refinement for IAV challenged ferrets. PS30 Refinement of Primary and Secondary Methods of Euthanasia in African Clawed Frogs (Xenopus laevis) MR Nichols*, T Martin, SE Thurston, J Keller Unit for Laboratory Animal Medicine, University of Michigan, Ann Arbor, MI Recommended euthanasia methods for amphibians often include a primary pharmaceutical method that deeply anesthetizes the animal followed by a secondary physical method that causes irreversible death. Reliable secondary euthanasia methods are especially important in amphibians, where death can be difficult to differentiate from deep anesthesia. However, application of these methods can be difficult, prone to error, and may have negative emotional impacts on operators and observers. We compared 5 primary methods of euthanasia and hypothermia as a secondary method in a group of 54 adult female African clawed frogs (Xenopus laevis). Six frogs per group were euthanized via the following 5 primary methods: immersion in 5 g/L tricaine methanesulfonate (MS-222), immersion in 10 g/L MS-222, intracoelomic injection with sodium pentobarbital (1100 mg/kg), ventral cutaneous application of 20% benzocaine hydrochloride gel (182 mg/kg), or dorsal cutaneous application of isoflurane (60 mL/kg). For MS-222, frogs were immersed to a depth not covering the nares until a time that euthanasia was assessed to be complete (median = 3 m, IQR = 0.5 m). Euthanasia was assessed through loss of spontaneous movement, loss of righting reflex, loss of withdrawal reflex, and expiration of buccal respiration and heartbeat. Signs of distress and ease of application were also assessed. 5 g/L MS-222 and benzocaine elicited the fewest signs of distress, with 5 g/L MS-222 causing death faster than benzocaine (P < 0.05). Isoflurane, 10g/L MS-222, and pentobarbital are not recommended due to aversive behaviors (i.e. increased activity, increased secretions or sloughing of skin, gulping of air, blinking) or difficulty in use. To assess hypothermia as a secondary method, 24 frogs were deeply anesthetized in 1.5 g/L MS-222, followed by 1 of these methods: removal of heart, placement in a refrigerator until cloacal temperature reached 5C followed by a freezer, placement directly into a freezer, or placement into a cooler containing dry ice. Frogs were monitored for cessation of buccal respiration, cessation of heartbeat, and for a cloacal temperature curve indicating complete freezing of the coelom. All secondary methods led to irreversible death. We conclude that freezing of adult Xenopus laevis frogs that have been deeply anesthetized or euthanized via cutaneous application of benzocaine gel or immersion in 5 g/L MS-222 is an easy to perform, reliable, irreversible method of euthanasia that does not result in signs of distress.

PS32 Propofol as an Effective Means of Euthanasia for Adult Zebrafish (Danio rerio) A Davis*, D Chu, JP Garner Comparative Medicine, Stanford University, Palo Alto, CA Despite the popularity of the zebrafish (Danio rerio) as a model organism in biomedical research, the most frequently used methods of euthanasia for these small fish (MS222 and ice bath) have multiple shortcomings with regard to animal welfare and human safety. Propofol has been known to cause rapid induction of anesthesia for many species including zebrafish, but its efficacy as a euthanasia agent for zebrafish has not been tested. Fifty-eight adult zebrafish were used in this project, with 8 to 9 fish per treatment group. Each fish was individually placed in a small tank containing water from their home tank plus ice, 250ppm MS222, 600ppm lidocaine hydrochloride, 100ppm propofol, or 150ppm propofol for a period of 20 or 30 m. Display of aversive behaviors (erratic swimming, piping at the surface), time to loss of righting reflex, time to cessation of opercular movement, time to loss of tank tap response, and time to recovery after removal to clean tank water were recorded. Propofol at both concentrations induced loss of righting reflex and opercular movement more quickly than MS222 or lidocaine, without display of aversive behaviors as seen with ice bath exposure. However, for fish euthanized with propofol, exposure duration was a significant predictor of recovery from anesthesia whereas dose was not. Of the animals exposed to propofol for 20 m, 3 animals (1 of 8 at 100ppm, 2 of 8 at 150ppm) experienced deep anesthesia with loss

of all measured responses but recovered within 30 m after being returned to a clean tank. A 30-m exposure to propfol at either concentration was sufficient for euthanasia of all animals tested. These findings suggest that exposure to propofol for a duration of at least 30 m may be an effective and humane means of euthanasia for adult zebrafish. PS33 Comparing the Effect of Capromorelin and Mirtazapine on Appetite in New Zealand White Rabbits J Draper*, EK Daugherity, M Martin-Flores, D Savson, E Lavin Cornell University, Ithaca, NY Inappetence is a welfare concern in rabbits, Oryctolagus cuniculus, that can lead to gastrointestinal (GI) stasis. Causes of inappetence and GI stasis include stress, pain, disease, poor diet, and opioid use. Treatments includes fluid therapy, enteral nutrition, GI motility stimulants, and appetite stimulants. There are no published studies evaluating efficacy of appetite stimulants in rabbits. We evaluated the effect of capromorelin, a ghrelin receptor agonist, and mirtazapine, antagonist of 5HT2c and H1 receptors, on appetite in subsequential studies in New Zealand White (NZW) rabbits. Nine male healthy NZW rabbits received 9 treatments: capromorelin 4 mg/kg PO SID, capromorelin 8 mg/kg PO SID, capromorelin 4 mg/kg PO BID, capromorelin 8 mg/kg PO BID, mirtazapine 0.5 mg/kg transdermal (TD) SID, and mirtazapine 1 mg/kg TD SID with saline PO SID, saline PO BID, and saline TD SID acting as controls for 3 d with at least a week washout period in a randomized crossover study. Feed intake and fecal output were monitored daily with body weight monitored biweekly. Statistical analysis showed significant increase in feed intake and fecal output for all groups of capromorelin and mirtazapine compared to control except for capromorelin 4 mg/kg and 8 mg/kg SID on fecal output. Mirtazapine significantly increased feed intake and fecal output when compared to capromorelin. Body weight significantly increased for mirtazapine 1 mg/kg compared to control. Next, 9 male post-operative (neuter) NZW rabbits received 1 of 3 treatments: capromorelin 8 mg/kg PO BID, and mirtazapine 1 mg/kg TD SID with saline PO BID acting as a control for 3 d. Statistical analysis did not show a significant difference in feed intake, fecal output, or body weight for any of the groups. There was a magnitude of difference regarding increased feed intake and fecal output for mirtazapine that is clinically meaningful. In summary, capromorelin and mirtazapine increased appetite in healthy NZW rabbits evidenced by increases in feed intake and fecal output with mirtazapine increasing appetite in post-operative NZW rabbits as well. We recommend using mirtazapine in rabbits due to its superior efficiency compared to capromorelin.

tion and decrease of adverse effects of individual drugs. While premedication with an injectable agent before inhalant anesthesia is routine in other species, mice are commonly induced with gas anesthesia alone. We hypothesized that premedication with ketamine or xylazine would safely reduce the stress of induction and lower the minimum alveolar concentration (MAC) of isoflurane. We premedicated mice with intraperitoneal injection of ketamine (100 mg/kg), xylazine (4 mg/kg), or isotonic crystalloid (0.1 ml) and examined the effects on isoflurane induction and MAC. Young adult (8-20-wk-old) male and female C57BL/6J mice (n = 40) were used. First, we video-recorded isoflurane induction under all test conditions and scored the videos according to a behavioral ethogram to identify signs of stress. Next, we anesthetized mice to determine the MAC value for each anesthetic protocol using quantile analysis. Lastly, using isoflurane concentrations determined to keep at mice at a surgical plane of anesthesia during the MAC testing experiment (ketamine 1.3; xylazine 1.6; control 2.2), we anesthetized mice and monitored their vital parameters under anesthesia for 60 min. Ketamine and xylazine had a significant (P = 0.02) effect on induction scores (control 8.5±0.7, ketamine 5.3±4.0, xylazine 3.3±1.5), where a lower score represents a less stressful induction. Ketamine treated mice displayed ataxia and tremors before induction. Both drugs had a MAC-reducing effect (ketamine 0.96; xylazine 1.20; control, 1.89). All mice survived 60 min of anesthesia. The average heart rates of mice receiving xylazine (327±27) and ketamine (406±45 bpm) were significantly lower (P < .001) than those of control mice (572±72). The average respiratory rates for control mice (54±17) were significantly lower (P <.001) than those of mice given xylazine (102±14) or ketamine (115±20). The higher heart rates and lower respiratory rates in the control group were likely largely the result of respiratory suppression and hypotension due to a higher isoflurane concentration. Balanced anesthesia, specifically premedication with ketamine or xylazine, has potential benefits in mice, including reducing the stress of isoflurane induction and lowering isoflurane requirements.

to learning deficits in children and a burden on the healthcare industry. The gut microbiome (GM) has been shown to play a role in central nervous system function, and differences in the taxonomic composition, and richness of the GM have been associated with anxiety-related behavior. The GM of specific pathogen-free (SPF) mice varies in composition and richness across suppliers of SPF mice, and substrains of mice from different suppliers are reported to display differences in anxiety-related behavior, although it is unclear whether those differences are due to the supplier-dependent differences in the GM or substrain divergence. We sought to determine whether the difference in diversity of these GMs affects anxiety-like-behavior phenotypes. Two colonies of CD1 mice were rederived in surrogate dams harboring either a high microbial diversity (CD1GM4) or low microbial diversity GM (CD1GM1), and underwent multiple behavior tests commonly used to test for anxiety-related behavior in mice. The 3 behavior tests that were performed were open-field exploration (OFE), light/dark transition (LDT), and elevated plus maze (EPM). Our results with the OFE test showed that CD1GM4 mice with high GM diversity travelled a significantly greater distance in the center zone of the open-field test than CD1GM1 mice with low GM diversity (P = 0.003), suggesting decreased anxiety-related behavior in CD1GM4 mice. LDT test showed that CD1GM4 mice also spent significantly more time in the light zone than mice with a lower diversity GM (P < 0.001), and results from the EPM test showed CD1GM4 mice travelled a further distance within the open arms than the CD1GM1 mice (P = 0.002), again indicating decreased anxiety-like behavior in CD1GM4 mice compared with CD1GM1 mice. These results demonstrate that supplier-origin GMs modulate behavior phenotypes. The data from this study will provide the scientific community with a novel system in which to study how the GM influences anxiety disorders. PS35 Evaluation of Microenvironmental Parameters in Trio Breeding Cages of Mice A Maxwell*, MG Stover, J Plunkard, JS Villano Johns Hopkins University, Baltimore, MD Trio breeding (a male and 2 dams) is a commonly used method of breeding mice in laboratory animal research. The Guide recommends 51 in2 of space for a dam with a litter, thus indicating that standard cages (~75 in2) may not be sufficient for trio breeding housing. However, the Guide also emphasizes that performance standards are important considerations for space requirements. The objective of this study was to evaluate the microenvironment of breeding trios to create performance standards for our institutional guidelines on mouse cage densities. BALB/c mice (n = 10 cages; each housing 1 male and 2 dams, each with a litter of ~ 7 pups within 7 d apart) were housed in IVCs changed every 2 wk. Microenvironmental variables (temperature, relative humidity, CO2, O2 and NH3 were measured at d 0, 1, 3, 5, 10, 14 of the cage change cycle). Results revealed that at every time point, cage temperatures (78.9°F + 0.56) but not relative humidity (40.1+ 1.9%) were significantly higher (than the acceptable ranges for the mouse housing room (67-77°F; 30-70%). O2 and CO2 had an inverse correlation, and cages were consistently hypoxic (20+0.19%; below normal room oxygen concentration, 21%) at every time point, and CO2 levels exceeded the OSHA recommendations of 0.5% starting at day 3 (0.6+0.19%). Interestingly, NH3 levels (5.27+9.7 ppm) remained below the NIOSH recommended exposure limit for humans (25 ppm) at all time points until d 14. Of note, animals remained clinically healthy during the entire experiment and litters were weaned without issues. In conclusion, the trio breeding microenvironment cage was suboptimal

due to the increased temperature, increased CO2 and decreased O2 levels. However, further studies are warranted to determine potential effects of these findings to the overall animal health and wellbeing. In addition, studies are lacking on the ideal rodent environment as literature often cites animal macroenvironmental or human standards. PS36 Pharmacokinetics of Gabapentin after Single, Oral Administration in Domestic Rabbits (Oryctolagus cuniculus) M Burton*1, R Conway3, N Mishkin3, LV Kendall1, K Mama4, H Knych2, M Sadar4 Laboratory Animal Resources, Colorado State University, Fort Collins, CO; 2Department of Molecular Biosciences and the K.L. Maddy Equine Analytical Pharmacology Laboratory, University of California-Davis, Davis, CA; 3James L. Voss Veterinary Teaching Hospital, College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, CO; 4Department of Clinical Sciences, College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, CO 1

Gabapentin is used to treat epilepsy and neuropathic pain and, more recently, it has been prescribed as an anxiolytic in both human and veterinary medicine. Gabapentin has gained favor for its use as an anxiolytic as it is not classified as a controlled substance and has a wide margin of safety. As rabbits are easily stressed by handling, transport, and medical procedures, we propose gabapentin could be used as an anxiolytic. Current doses recommended for rabbits are extrapolated from other species or from limited studies. In this study, 3 male and 3 female 7-mo-old New Zealand white rabbits received a single dose of oral gabapentin at 25 or 50 mg/kg in a randomized crossover design. Plasma samples were obtained at 0, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 8, 12, 24, and 48 h post administration and concentrations determined using liquid chromatography-tandem mass spectrometry. Sedative effects were also scored at all time points. Pharmacokinetic analysis revealed mean peak plasma concentrations of 17,695 and 16,830 ng/mL and mean time to maximum plasma concentrations at 1.75 and 1.5 h for the 25 and 50 mg/ kg doses, respectively. These results suggest nonlinear absorption may occur, as doubling the dose did not result in increased plasma concentrations. Rabbits were mildly to moderately sedated at 2-3 h with 25 mg/kg and 1.5-3 h with 50 mg/kg with none experiencing profound sedation. Based on these results, further evaluation of oral gabapentin at a dose of 25mg/kg as an anxiolytic for rabbits is recommended. PS37 Assessment of Extended-release Buprenorphine in Comparison to Immediate-release Buprenorphine in a Murine Laparotomy Model G Chan*, MR Nichols, C Si, L Kennedy Unit for Laboratory Animal Medicine , University of Michigan, Ann Arbor, MI Buprenorphine is commonly used by researchers for postoperative pain relief in rodents. Currently, immediate-release formulations of buprenorphine (Bup-HCl) require frequent handling and restraint of animals for appropriate dosing, which can subsequently increase stress and impair healing in surgical models. Frequent dosing intervals also require increased labor and compliance from research personnel, consequently increasing the potential for falling below therapeutic concentrations. A recently approved FDA-indexed extended-release buprenorphine formulation may be an appropriate alternative to Bup-HCl

PS38 Effects of Analgesic Regimens on Appetite in New Zealand White rabbits (Oryctolagus cuniculus) Z Hsi*1,2, J Theil1, R Oates1,2, BW Ma1 Campus Veterinary Services, University of California, Davis, Davis, CA; 2School of Veterinary Medicine, University of California, Davis, Davis, CA 1

Opioids and NSAIDs are frequent analgesics used in rabbits, whether in a clinical veterinary or laboratory setting. Rabbits are especially sensitive to adverse effects related to these analgesic regimens and may develop poor appetite and resulting gastrointestinal stasis. However, it is unclear whether these adverse effects are solely related to the analgesics or are a response to the restraint and injections required for administration. We compared the gastrointestinal side effects of buprenorphine and carprofen to their saline controls in New Zealand White rabbits following a nonsurgical anesthetic event. Nine rabbits (3 females and 6 males, aged 8 to 20 mo) randomly rotated through 5 treatment groups with a 7-d washout period between treatment periods: anesthesia control, buprenorphine (0.05 mg/kg SC every 12 h for 72 h), carprofen (5 mg/kg SC every 24 h for 72 h), twice daily saline control (equivalent volume to buprenorphine dosage SC every 12 h for 72 h), and once daily saline control (equivalent volume to carprofen dosage SC every 24 h for 72 h). Generalized linear mixed models were used to assess food intake, water intake, and fecal output over a 7-d period following anesthesia. Post hoc analysis showed that buprenorphine-treated animals had a significant 4-d decrease in food intake and 3-d decrease in fecal output compared to baseline. No other treatment groups showed any changes in food intake or fecal output compared to baseline. Of note was that animals that received twice daily saline had significantly greater appetites than all other treatment groups on d 7. These findings demonstrate that buprenorphine significantly depresses appetite in rabbits and that increased restraint and injections have minimal effect on appetite despite the possibility of increased stress.

Ornithonyssus bacoti, the tropical rat mite, is a zoonotic bloodsucking mite which may infest mouse colonies via wild rodent vectors. Heavy infestations in mouse colonies have been documented to cause anemia, alopecia, and decreased reproductive performance. In mid 2020, our institution experienced increased levels of wild mice, which were found to be infested with O. bacoti diagnosed by microscopic exam and confirmed by fur swab PCR. O. bacoti is often categorized as a rat pathogen, and is not included as a common wild rodent add-on test for direct animal PCR sampling, so it is likely overlooked during surveillance of wild rodents. We elected to add O. bacoti to our quarterly health monitoring exhaust air dust (EAD) testing, increase wild mouse control measures, and treat the environment with a permethrin spray in an attempt to prevent colony animal infestation. Initial quarterly EAD health monitoring results in September of 2020 were negative for O. bacoti. However, in early 2021, multiple IVC racks tested positive for O. bacoti via quarterly testing. Historically in the literature, O. bacoti outbreaks of research mice were not identified until mite burden was high enough to cause dermatitis on animal care workers. Due to modern molecular diagnostics and proactive EAD surveillance, our institution was able to identify and initiate eradication measures in a timely manner. To the best of our knowledge, this is the first report to successfully identify O. bacoti using environmental PCR techniques. This outbreak demonstrates the importance of screening for O. bacoti in facilities with wild rodent issues, and highlights unique considerations when managing O. bacoti infestations. PS40 The Prevalence and Contrasting Outcomes of 2 Common Types of Ulcerative Dermatitis DL Fong*, M Fink, L Habenicht, J Taylor, CA Manuel, JK Leszczynski OLAR, University of Colorado Denver, Aurora, CO Ulcerative dermatitis (UD) remains a common disease in laboratory mice. At our institution, we have informally classified UD into 2 main types based on clinical presentation and response to intervention: typical UD and atypical UD. Typical UD frequently involves superficial abrasions and/or scabs on the dorsal neck or ears. As previously reported, this type of UD generally heals well following a nail trim due to attenuation of self-trauma associated with repeated scratching. Atypical UD is not currently well-characterized and involves full thickness skin lesions that are primarily located on the lateral thorax and abdomen or limbs. We colloquially call atypical UD lesions “lick-chews” as we believe that excessive grooming behavior is the primary mechanism of injury. Anecdotally, these lesions are refractory to nail trims, and other topical and systemic treatments that have been described for the management of typical UD. To provide objective data, we retrospectively examined our electronic veterinary medical records for the prevalence and outcomes of these types of UD cases over a 3-mo timeframe. The average mouse daily census was approximately 22,300 cages and there were 2,456 completed mouse health reports during this period. Forty percent of health reports were classified by veterinary staff as UD. Atypical UD lesions accounted for 16% (160/975) of all UD cases. More importantly, mice with typical UD were reported healed in 74% (603/815) of cases, whereas animals with atypical UD lesions were reported

in mice and rats. The purpose of this study was to investigate efficacy of the new extended-release buprenorphine (Bup-ER) in a murine laparotomy model and compare its analgesic effects to Bup-HCl in the first 72 h after surgery. Six female and 12 male C57Bl/6J mice were randomly and evenly allocated to receive either Bup-ER (3.25 mg/kg) once presurgically or Bup-HCl (0.1 mg/kg) presurgically and then every 8 h for 72 h postsurgically. Mice underwent a sham laparotomy and were weighed daily and assessed for pain based on a cageside ethogram (appearance of hair coat, coordination and posture, and overall condition), behavioral assays (nesting consolidation test, rearing frequency), and nociception via von Frey testing at 6, 12, 24, 48, and 72 h postsurgically. Response variables were analyzed with a repeated measures 2-way ANOVA and posthoc comparisons were performed. Weight was significantly decreased from baseline at 48 h in the Bup-ER group and at 72 h in both groups. There were significant changes in cageside ethogram, nest consolidation scores, and rearing frequency at early time points as compared to presurgical baseline in both treatment groups, but no significant differences were noted between treatment groups. There were no significant differences in nociception between treatment groups or from baseline. These results indicate that extended-release buprenorphine has comparable efficacy to the immediate-release formulation and may be a viable alternative for postoperative analgesia in mice.

healed in 12.5% (20/160) of cases. This data demonstrates the prevalence and importance of atypical UD lesions. While many papers have evaluated treatments for UD, we do not believe that studies have specifically assessed treatment efficacy by specific UD type. Atypical UD lesions should be further characterized to help develop more efficacious treatments for this challenging clinical presentation. PS41 Cobalamin Supplementation in the Treatment of Chronic Gastrointestinal Disease in a Cynomolgus Macaque (Macaca fascicularis) LM Lamoureux*, LC Halliday Biologic Resources Laboratory, University of Illinois at Chicago, Chicago, IL An 8-y-old, 2.8 kg, female, pair-housed cynomolgus macaque presented for chronic diarrhea and poor hair coat. On initial cage side exam, mentation and appetite were appropriate. The feces in the cage were voluminous, soft, and pale. The hair coat was greasy and unkempt. There were no remarkable findings on physical exam or abdominal ultrasound. Complete blood count and serum chemistry revealed moderate hypoproteinemia and hypoalbuminemia. Fecal occult blood, floatation, and wet mount were unremarkable. Fecal PCR and cultures were negative for common enteric pathogens, but indicated heavy growth of commensal organisms. Diet modification was attempted with high fiber and high protein (25%) biscuits with no improvement. Serum cobalamin and folate analysis revealed a marked decrease in cobalamin with normal folate compared to age and sex matched conspecifics. Cobalamin supplementation was initiated resulting in clinical improvements in fecal consistency, hair coat, protein, albumin, and cobalamin. Cobalamin supplementation was continued for 10 mo and was terminated based on clinical resolution and enrollment into a neuroscience study. After 6 mo on study, the study endpoint was reached and a necropsy was performed. Grossly, the gastric and colonic mucosa were thickened, and the pancreas was small at 6 cm in length. Histopathology results revealed severe atrophic lymphoplasmacytic gastritis and diffuse acinar cell atrophy of the exocrine pancreas. Immunohistochemistry of the stomach revealed a mixed inflammatory infiltrate of T and B cells. There are reports of Helicobacter spp. causing severe gastritis in cynomolgus macaques; however, Steiner (silver) stain did not reveal the presence of argyrophilic organisms. Notably, atrophy of the exocrine pancreas has been regarded as a rare incidental finding. Although considered to have low sensitivity and specificity, evaluation of serum cobalamin and folate levels may provide useful insight into underlying pathologies and course of treatment in nonhuman primates with chronic diarrhea. PS42 Acute Cholangiohepatitis in a Colony of Common Marmosets (Callithrix jacchus) N Castell*, S Powers, K Gabrielson, J Izzi Johns Hopkins School of Medicine, Baltimore, MD Seven experimentally naïve common marmosets (Callithrix jacchus) presented individually over the course of 9 mo with acute onset of severe lethargy and dull mentation. Perimortem serum chemistries revealed marked elevations in GGT, ALP, AST, and ALT, indicative of hepatobiliary disease. Complete blood counts were mostly unremarkable, with mild neutrophilia in some cases. Abdominal ultrasounds showed increased echogenicity in liver parenchyma and within the gallbladder lumen, thickening of the gallbladder wall, abdominal effusion, or were unremarkable. De-

spite extensive supportive care and antibiotic therapy, all animals experienced a rapid decline in clinical condition leading to death or euthanasia within 48 h of presentation. Necropsy revealed severe necrosuppurative cholangiohepatitis with gallbladder obstruction. Postmortem cultures from multiple organs isolated predominantly Pseudomonas and E. coli spp. Based on clinical and necropsy findings, the likely cause of bacterial cholangiohepatitis was due to ascending infection from the gastrointestinal tract into the biliary tree, ultimately leading to septicemia. PCR testing for multiple viral pathogens was negative. Investigation into sources of the bacterial infection led to the discovery of contamination of water supply equipment with Pseudomonas aeruginosa. The entire water supply system was replaced immediately, and no additional cases have since occurred. Interestingly, though all animals in the colony received similar exposure through the common water supply, only a small subset of marmosets showed any indication of clinical disease. The incidence of mortality due to cholangiohepatitis in the colony was 3.4%, with predominantly adult males over 7 y of age being affected. Genetic predisposition may play a role in susceptibility, as most cases (6/7) had a common origin outside the facility. These cases demonstrate the predisposition of marmosets to Pseudomonas infection through chronic oral exposure, as well as the importance of using environmental testing to monitor and validate routine sanitization practices. PS43 Successful Treatment of Acute Buoyancy Disorder in a Common Goldfish (Carassius auratus) Using an Improvised Hyperbaric Chamber CF Janssen* CLAMC, UTHealth, Pearland, TX A common goldfish with normal anatomy presented acutely with classic signs of buoyancy disease, specifically positive buoyancy, after being overfed. The fish was actively struggling to swim downward, resulting in an abnormal head down posture. Opercular movements were rapid and pronounced. Subjectively the fish appeared to be distressed. Any cessation in effort resulting in rapid floating towards the surface. As the fish became fatigued and rested at the surface, it was noted that 1-2 mm of the body was above the water confirming significant positive buoyancy. The abdomen was not obviously distended, however, the peri-anal region did appear to bulge, suggesting intraabdominal pressure in a non-distensible abdomen. Based on the history of overfeeding, it was determined that the excess gas was as likely to be within the GI tract, ie colic, as within the swim bladder. Needle aspiration of air from the swim bladder is often recommended as treatment for positive buoyancy, however, in this instance, without available imaging or anesthesia, with suspicion that the swim bladder was not the issue, and with high risk of GI perforation, this option was rejected. It was decided to reduce the volume of the air bubble by compressing the fish in an improvised hyperbaric chamber. This immediately alleviated the tympany, potentially relieving any discomfort and potentially improving blood flow to affected tissues, and eliminated the struggle to maintain buoyancy. Subjectively the fish appeared to be less distressed, with less frantic swimming motion, when compressed. The pressure was maintained for a short period, then slowly released, allowing the bubble opportunity to be redistributed before re-expanding to the original volume. This was repeated several times in a first session, and again several times 4 h later. The fish eventually defecated a large air bubble, trapped in mucus, which remained attached to the anus long enough to be photographed. One year later the fish is well and has had

PS44 Evaluation of Proparacaine for Use during Tuberculin Skin Tests in the Common Marmoset (Callithrix jacchus) JL Haupt*, RM Kramer, M Jamiel, A Johnson Massachusetts Institute of Technology, Cambridge, MA Tuberculin skin test (TST) is the primary screening tool for M. tuberculosis surveillance in common marmosets (Callithrix jacchus). In our colony, all animals are tested during semiannual health examinations under alfaxalone sedation (7-10 mg/kg IM). Mammalian old tuberculin (MOT) is injected intradermally into the superior palpebral at the lateral canthus. The palpebral skin of the common marmoset is thick and many marmosets react to the injection of MOT with the movement of the head, eyelids, or scratching of the eye immediately after injection. Failed injections, multiple needle sticks, and scratching can lead to palpebral erythema, bruising, and inflammation, leading to indeterminate or false-positive test results. This project aimed to evaluate the use of proparacaine, a rapid-acting local anesthetic for ophthalmic use, to diminish adverse reactions from TST using MOT in the common marmoset. During semiannual health exams, animals (n = 66) were assigned in a blinded manner and either given 1 drop of artificial tears (control, n = 35) or proparacaine (treatment, n = 31) in the eye assigned for TST at least 1 min before intradermal placement of the MOT. The dose of alfaxalone, animal weight, body condition score, and age was recorded along with reaction to the injection. TST reaction grade was recorded at 24, 48, and 72 h post-injection. There was no difference with the use of proparacaine on needle reaction, injection reaction, movement during injection, scratching, bleeding, or bruising post-injection, and 24, 48, and 72 h TST grade reaction scores. However, higher alfaxalone doses were associated with decreased needle reaction, injection reaction, movement during injection, scratching post-injection, and 24 and 72 h TST grade reaction scores. Inverse prediction was used to identify decreased reaction to injection at an alfaxalone dose of 10 mg/kg. The results of this project show that proparacaine had no impact on TST reaction in the common marmoset. However, higher doses of alfaxalone diminished adverse reactions to injection and lead to less erythema, bruising, and indeterminate TST reaction grades in the common marmoset. Based on the findings of this project, sedation with 10 mg/kg of alfaxalone is advocated for TST in the common marmoset. PS45 Management of Encephalitozoon cuniculi Infection in a Breeding Colony of African Spiny Mice (Acomys spp.) DM LeMoine*, D Moorman-White, K Nolan Comparative Medicine, University of Rochester, Rochester, NY A 5-wk-old male African spiny mouse (Acomys spp.) born inhouse was euthanized due to acute onset ataxia, lethargy, weakness, and dyspnea. Histopathology revealed meningoencephalitis and interstitial nephritis with Gram-positive microsporidia consistent with Encephalitozoon cuniculi present in both tissues. We performed follow up testing to determine the prevalence of the pathogen within the colony. PCR of urine and feces detected active shedding of E. cuniculi in 1 of 4 cages, and 55% (n = 11) of the colony was seropositive for E. cuniculi antibodies. Because E. cuniculi is a zoonotic pathogen that can infect a wide range of mammalian hosts, a multipronged control strategy was implemented to control the agent while preserving valuable breeding

animals for future research needs. We quarantined the colony in place and informed personnel of additional PPE requirements. Two cages of offspring born in-house were culled for experimental use. For the remaining animals, we separated breeding pairs to prevent vertical transmission and initiated treatment with two, 4-wk courses of fenbendazole-medicated feed. Shortly after starting treatment, one additional juvenile was found dead and, although seronegative, confirmed to be infected based on PCR of brain tissue. PCR testing of urine and feces was negative by the midpoint of treatment and remained negative after completing the full 8-wk treatment course. No additional clinical signs or mortality were seen. None of the animals that were previously seronegative (n = 4) or that were born during the treatment period (n = 5) seroconverted. We believe that at least 1 of the founder animals was carrying E. cuniculi, which is not included in our routine quarantine testing, upon import. Fenbendazole treatment effectively prevented further spread of E. cuniculi within the colony. The use of multiple testing strategies was critical for fully characterizing the infection, as tissue PCR detected the pathogen in animals that were seronegative and not actively shedding spores in urine or feces. It is possible that organisms persist in the tissues of previously infected animals. Therefore, we plan to continue regularly screening for E. cuniculi by exhaust air dust PCR and tissue PCR when available. PS46 Spontaneous Acute T-cell Leukemia in a Specific-Pathogen Free Rhesus Macaque (Macaca mulatta) G Campellone*, M Stovall Veterinary Medicine, Yerkes National Primate Research Center, Stone Mountain, GA A 5-y-old, female rhesus macaque (Macaca mulatta) housed in a specific-pathogen free (SPF), outdoor breeding colony, presented to the hospital with lameness. Physical examination and radiographs revealed mild effusion in the right stifle. A soft tissue injury was suspected, and analgesics and cage rest were initiated. Bloodwork revealed anemia and a marked leukocytosis, 27.02k/ ul. The animal was re-examined the following day due to reports of abnormal respiration, stertor, and bilateral epistaxis. Respiratory signs improved once the nares were cleared and the animal was returned to the cage for close monitoring. Three d later the animal was re-examined and noted with bilateral epistaxis and crackles in all lung fields. Thoracic radiographs were consistent with pneumonia, and broad-spectrum antibiotics were initiated. Repeat bloodwork revealed continued anemia and a progressive leukocytosis (40.85k/ul). Over the next 9 d, multiple examinations and radiographs were performed. While the pneumonia resolved, the hindlimb lameness progressed bilaterally and the leukocytosis consistently progressed, increasing to 47.26k/ul and then to 52.32k/ul. Acute leukemia was suspected at this time. The patient was examined the following day to obtain a bone marrow aspirate, however, severe generalized lymphadenopathy, cardiovascular decompensation, and progressive weight loss were noted on examination. Due to the animal’s decline, and the presumptive diagnosis of acute myeloid leukemia, the animal was euthanized. Gross pathology findings and histology were consistent with T-cell leukemia. No abnormalities were noted in the stifles; however, joint pain is associated with leukemia. In nonhuman primates, T-cell leukemia is typically associated with STLV-1; however, both serology submitted 8 mo prior to initial clinical presentation and PCR submitted at necropsy were negative. To the authors’ knowledge, this is the first reported case of spontaneous acute T-cell leukemia in an SPF rhesus macaque. It’s important to recognize this as a potential neoplasia, even in SPF nonhuman primate colonies.

no further issues. Here we suggest that hyperbaric therapy be considered as a treatment option for acute positive buoyancy disease of fish, and suggest that a better quality, less hastily improvised hyperbaric chamber might be a useful addition to the fish veterinarian’s toolbox.

PS47 Prevalence of Infectious Agents in Zebrafish Colonies Based on Real-time PCR (2015–2019) MJ Crim*1, ML Hart2, CL Besch-Williford3, RS Livingston2 Molecular Diagnostics and Microbiology, IDEXX BioAnalytics, Columbia, MO; 2R&D and Scientific Affairs, IDEXX BioAnalytics, Columbia, MO; 3Pathology, IDEXX BioAnalytics, Columbia, MO 1

Naturally occurring infections can adversely affect research, including invalid or misinterpreted experimental data, zoonotic infections, or elevated morbidity and mortality. Prevalence of infectious agents is an important consideration in risk assessments for import procedures, quarantine, and colony health monitoring. We report the positivity rate of real-time PCR results for 18 infectious agents in pooled zebrafish and environmental samples submitted by 230 biomedical research institutions over a 5-y period to a major commercial diagnostic laboratory. Prevalence varied widely by agent, and for some agents varied widely among submitting institutions. The overall positivity rate also varied by sample type for each agent, with a higher percentage of positive test results in pooled zebrafish samples for Zebrafish picornavirus and all common parasites except for Myxidium streisingeri. A higher percentage of environmental samples tested positive for Mycobacterium spp., facultative pathogens that participate in system biofilms, compared to pooled zebrafish samples. The most frequently detected infectious agents in pooled zebrafish samples were Zebrafish picornavirus (26.5 %), Pseudoloma neurophilia (19.9 %), M. streisingeri (16.0 %), M. chelonae (9.7 %), Pseudocapillaria tomentosa (7.6 %), and M. haemophilum (2.6 %). In contrast, M. chelonae (44.8 %), M. fortuitum (35.1 %), M. streisingeri (23.5 %), M. gordonae (21.8 %), M. abscessus (18.7 %), and Zebrafish picornavirus (16.7 %) were the most frequently detected agents in environmental samples. Some pathogens may remain undetected by exporting institutions relying on detection via less sensitive sample types. Institutional prevalence from the exporting institution is more useful than overall prevalence for assessment of importation biosecurity risk since the institutional prevalence for several agents can differ substantially from overall prevalence. Thus, obtaining detailed zebrafish colony health information from exporting institutions, including sampling methodology, is critical to assessing the biosecurity risks associated with the importation of zebrafish lines. PS48 Prostaglandin F2α and Dexamethasone in the Treatment of Closed-Cervix Pyometra to Preserve Breeding Function in a Bitch L Hagan*1, V Stora2, JO Marx1, C Vite2 ULAR, University of Pennsylvania, Philadelphia, PA; 2RCAM, University of Pennsylvania, Philadelphia, PA 1

A 5-y-old 21.0kg mixed-breed bitch heterozygous for the gene causing globoid cell leukodystrophy (Krabbe disease) was reported by animal care staff for lethargy and one episode of vomiting. On physical examination she was quiet, alert, and responsive. Her mucus membranes were pink, tacky, with a capillary refill time of < 2 seconds, and her abdomen was mildly distended and firm on palpation. Ultrasonography of her abdomen revealed uterine horns filled with hyper to hypoechoic fluid without vaginal discharge. Complete blood count and chemistry revealed dehydration (total protein 8.9 g/dL, BUN 91 mg/dL, creatinine 2.0 mg/dL), hyperphosphatemia (13.6 mg/dL), and hypercholesterolemia (538 mg/dL). Serum progesterone measured 23.3 ng/mL (normal less than 1.0 ng/mL). The diagnosis of closed-cervix pyometra was made. Following the diagnosis, a

veterinary theriogenologist prescribed and initiated treatment of dexamethasone-SP 0.1 mg/kg subcutaneously once daily for 7 d, and prostaglandin F2α for luteolysis and smooth muscle contraction for the expulsion of uterine contents, (0.05 mg/kg SC BID for one day, then 0.1 mg/kg SC BID until normal serum progesterone), buprenorphine (0.02 mg/kg SC BID), amoxicillin/ clavulanic acid (25 mg/kg PO BID), enrofloxacin (10 mg/kg PO SID), maropitant (1 mg/kg SC SID), ondansetron (0.5 mg/kg SC BID), and subcutaneous fluids (10-15 ml/kg SC BID). The patient improved within 3 d, with increased appetite and activity following tolerance to prostaglandin. Bloodwork abnormalities resolved after 6 d of treatment and serum progesterone reduced to 0.5 ng/mL. Prostaglandin therapy was discontinued after 8 d. Although ovariohysterectomy is commonly the treatment of choice for closed-cervix pyometra, this case demonstrates successful medical management of a closed-cervix pyometra within a valuable, middle-aged breeding bitch. PS49 C57BL/6 Mouse Sperm Quality Analysis, Fertilization Rates, and Embryonic Development Competency following Preservation at 4°C for 18, 48, and 72 Hours S Gerb*, K Gustafson, C Agca, Y Agca Veterinary Pathology , University of Missouri, Columbia, NJ Around the world, investigators are creating mouse models of human disease. These models are time consuming and expensive to create. It is not uncommon for genetically modified animals to die unexpectedly, potentially causing extinction of a line. The collection of epididymal sperm for assisted reproductive techniques, such as in vitro fertilization is a viable method to reanimate lines. However, not all institutions are equipped to perform such procedures. Therefore, there may be a need to ship animals to institutions that have such capabilities. To determine the ideal shipping conditions and timeline, 6-12-mo-old male C57BL/6 mice were randomly placed in 1 of 3 time point groups: 18 h (n = 12), 48 h (n = 14) and 72 h (n = 16). Animal were then then euthanized via CO2, and sperm was collected from 1 cauda epididymis for fresh sperm analysis. Mice with the remaining cauda epididymis were then placed in a refrigerator at 4°C. After the appropriate time had passed (18 h, 48 h, or 72 h), sperm was collected from the remaining cauda epididymis and analyzed. Sperm was significantly less motile following 18, 48 or 72 h at 4°C (P < 0.001) however, there was no significant differences in progressive motility between groups for both fresh and aged sperm (P = 0.465). Fresh sperm and sperm from the 48 h and 72 h group was then used to perform in vitro fertilization using fresh oocytes from C57BL/6 mice super ovulated with PMSG and hCG. The percent of fresh oocytes fertilized was significantly higher in the fresh group in comparison to the 72 h group (P > 0.001) and sperm from the 48 h group fertilized significantly more oocytes than the 72 h group (P > 0.001). The percentage of fertilized oocytes that went on to develop into morula and blastocyst were assessed. There were no significant differences in morula (P = 0.324), or blastocyst development rates (P = 0.147) between groups. The data collected from this study suggests that sperm collected from animals that have been preserved at 4°C for 48 h or less would provide the best outcome for in vitro fertilization and reanimation of a line. Practically, our study suggests that mice should be shipped via 2-d shipping on ice (about 4°C) for the best outcome.

Ovarian cancer is the most deadly gynecological malignancy and fifth leading cause of cancer-related deaths in women. Most patients are diagnosed at late stages of the disease, which is marked by chemoresistance, high rates of recurrence, and significant abdominal tumor burden evidenced by ascites accumulation. We previously demonstrated that glutathione peroxidase 3 (GPX3), an extracellular antioxidant enzyme, has heterogenous expression in ovarian cancer, where high GPX3 expression is associated with decreased patient survival and increased tumor stage. The main function of GPX3 is to reduce hydrogen peroxide (H2O2) to water with the help of glutathione. Therefore, a decrease in GPX3 expression may leave tumor cells vulnerable to increased reactive oxygen species in the extracellular tumor microenvironment. We hypothesized that ovarian cancer with decreased GPX3 expression that has metastasized to the peritoneal cavity will be less aggressive than ovarian cancer with normal GPX3 expression. We developed 2 stable mouse ovarian cancer (ID8) GPX3 knock-down cell lines using lentiviral shRNA constructs (shGPX3 #1 and #2). Female C57BL/6 mice were injected intraperitoneally with either 1 x 106 control ID8 (n = 7) or 1 x 106 GPX3 knockdown ID8 cells (n = 9) and were serially imaged weekly using in vivo bioluminescence imaging for at least 8 wk when they began to develop ascites. At necropsy, the amount of ascites was quantified and tumor burden documented. Mice injected with GPX3 knockdown ovarian cancer cells either never developed tumors or showed increased survivability compared to control ID8 mice. The mice that did develop tumors showed delayed tumor progression but similar tumor burden compared to controls. These results support evidence that decreased GPX3 expression is antitumorigenic, although more research is needed to determine if this conveys an increased susceptibility to certain treatments.

Light can significantly influence regulation of circadian rhythms of physiology and metabolism in laboratory animals. Light-emitting diode (LED) light is a rapidly emerging technology, yet little is understood regarding its impact on animal circadian and neuroendocrine responses. Previous studies from our laboratory demonstrated that exposure to LED light enriched in the blue-appearing portion (465-480 nm) of the visible spectrum at daytime (bLAD) enhances these responses in mice compared to those housed under broad spectrum (300-740 nm) cool white fluorescent (CWF) light. Here, we hypothesize that daytime exposure of adolescent Sprague Dawley rats to bLAD, compared to CWF light, positively influences circadian regulation of select neuroendocrine hormones. Control animals (n = 36m, 36f) were maintained on a standard IVC system under CWF light, whereas

experimental animals (n = 36m, 36f) were housed inside a novel light-containment IVC system emitting bLAD light; both groups were housed for 30 d under a common lighting regimen 12L (68.8 ± 5.2 lux; 168.6 ± 12.8 µW/cm2):12D (0 lux). On d 30, rats were anesthetized with ketamine/xylazine and terminal collection of arterial blood performed to quantify serum melatonin, corticosterone, insulin, and glucose across 6 circadian time points (0400, 0800, 1200, 1600, 2000, 2400). Compared to CWF males and females, rats in bLAD lighting evinced a 6-fold higher peak in nighttime serum melatonin (P < 0.05). Differences in serum corticosterone were sex dependent, as CWF and bLAD females produced more corticosterone overall than CWF and bLAD males (P < 0.05), respectively. While CWF and bLAD males exhibited significantly higher serum glucose compared to females, there was no difference in serum insulin among sex (m or f) nor lighting conditions (CWF or bLAD). This data show that housing SD rats under bLAD lighting conditions has a positive impact on circadian melatonin rhythm without increasing overall serum corticosterone production, nor altering glucose metabolism and production of serum insulin. Future studies should examine effects of long-term (>3 mo) housing of both adolescent and adult animals under bLAD lighting on circadian regulation of these neuroendocrine and metabolic parameters. PS52 Feline Immunodeficiency Virus Treatment with Combination Antiretroviral Therapy Assessed Using Digital Droplet PCR J Kim*1, E Behzadi2, M Nehring2, CA Miller3, S Carver4, S VandeWoude2 Laboratory Animal Resources, Colorado State University, Fort Collins, CO; 2Microbiology, Immunology, and Pathology, Colorado State University, Fort Collins, CO; 3Veterinary Pathobiology, Oklahoma State University, Stillwater, OK; 4Biological Sciences, University of Tasmania, Hobart, , Australia 1

Feline Immunodeficiency Virus (FIV) is a naturally occurring retrovirus that infects domestic cats and causes progressive immune dysfunction. Although highly effective treatments, including a combination antiretroviral therapy (cART), have been developed for human immunodeficiency virus, there is no effective therapy for FIV. This study aimed to assess a cART, composed of 2.5 mg/kg Doulutegravir, 20 mg/kg Tenofovir, and 40 mg/kg Emtricitabine, as a treatment for FIV in domestic shorthaired cats. Eighteen 6 to 10-mo-old cats in total were used with female intact and male neutered cats equally distributed among cART, placebo, and control groups. We inoculated 12 cats with FIV in addition to 6 naïve cats serving as controls, and we collected whole blood to quantify viral and proviral loads via digital droplet PCR pre-FIV inoculation, weekly postinoculation at wk 1-6, and every other wk at wk 8-24. Beginning wk 4, we injected cART (n = 6) or a placebo (n = 6) containing 1 mL of 15% kleptose, the cART vehicle, subcutaneously once daily to the FIV-infected cats. Infection peaked at wk 2 with mean viral loads noted at 6.43e6 and 12.4e7 copies/ mL among cART and placebo cats, respectively; mean proviral loads were noted at 5.43e4 and 4.94e4 copies/106 cells among cART and placebo cats, respectively. Viral and proviral loads steadily declined after wk 2 and were not statistically significant. Hematologic analysis on wk 4, 6, 10, and 16 demonstrated marked neutropenia in placebo cats compared to cART (P = 0.05), lowest at week 6 with mean absolute values/uL of 651 and 1340, respectively. Mean neutrophil values in cART cats normalized by week 16, but placebo cats remained neutropenic. No clinical signs associated with neutropenia were observed. These results suggest that this cART protocol does not reduce FIV viral and proviral loads but may impact hematologic impacts of FIV infection.

PS53 Examining the Transmission of Nippostrongylus brasiliensis in Mice to Assess Biosecurity Risks when Used as an Animal Model RJ Floyd*1, RJ Ricart Arbona1,2, NS Lipman1,2 Tri-Institutional Training Program in Laboratory Animal Medicine and Science, New York, NY; 2Center of Comparative Medicine and Pathology, Memorial Sloan Kettering and Weill Cornell Medicine, New York, NY 1

Nippostrongylus brasiliensis (Nb) infected mice are commonly used to study systemic and mucosal immune responses due to the parasite’s ability to induce a potent Th2 type response. There is no clear consensus regarding what biosecurity measures should be employed when housing mice and rats infected with Nb. Transmission is anecdotally reported to not occur when infected mice are co-housed with naive mice, if the cage is changed twice weekly, as the infective L3 larvae take approximately 5 to 6 d to develop under optimal temperature and humidity. We sought to determine what conditions, if any, favor horizontal transmission to inform biosecurity decisions when using the model. Female NOD.Cg-Prkdcscid Il2rgtm1Wjl/Sz (NSG; n = 12] and C57BL/6J (B6; n = 12) inoculated with 750 Nb L3 larvae were cohoused with naïve mice (NSG; n = 24 and B6; n = 24) at a ratio of 1 infected:2 naïve mice per cage for up to 28 d with cages changed on a 14-d interval. We also assessed whether larval development can occur to the L3 stage when Nb ova-containing fecal pellets are maintained in 3 different environmental conditions (dry, moist, and soiled bedding) and whether infection results when naïve mice (NSG; n = 9) are housed in cages with infective L3 larvae-spiked (10,000/cage) soiled bedding. NSG mice (n = 3) were also gavaged with embryonated and non-embryonated Nb eggs to model the potential for infection to occur following coprophagy. Both naïve NSG (8/12) and B6 (8/12) cohoused with an infected cage mate passed Nb eggs in feces within 4 d of cohousing for short intermittent periods, presumably a result of coprophagy as adult worms were not detected at euthanasia on d 28. While eggs were able to develop into L3 larvae in 2 environmental conditions, none of the NSG mice housed in cages with L3-spiked bedding or gavaged with eggs became infected with Nb. These findings demonstrate that horizontal transmission does not occur even when mice are housed in static caging with 14-d cage changing intervals. Results from this study can be used to make recommendations regarding biosecurity practices to employ when working with the Nb-infected mouse model. PS54 SARS-CoV-2 Variant Pathogenesis and Effects of Preexisting Immunity in Syrian Hamsters J Plunkard*1, M Lowman2, K Mulka1, K Carter2, JS Villano1 Department of Molecular and Comparative Pathobiology, Johns Hopkins University, Baltimore, MD; 2Johns Hopkins University, Baltimore, MD 1

SARS-CoV-2 (SCV2) has had a historical impact on the globe, with over 3.5 million COVID-19 related deaths since its discovery. As new variants emerge, it is crucial to understand differences in their pathogenesis and the influence prior infections may have. This study investigates the pathogenesis of 5 variants and the impact of preexisting immunity on variant pathogenesis using the Syrian hamster model. We hypothesize that variants will cause significant clinical disease and lung pathology, and that preexisting immunity will result in significantly less severe clinical signs. To examine variant pathogenesis, 6-8-wk-old Syrian hamsters (n = 4/sex/time point/variant) were inoculated intranasally (50 ul/nare of infectious dose) under ketamine/xylazine

124

sedation and euthanized at 2, 4, or 7 d post-infection (dpi). Body weights (BW) and clinical scores (rough hair coat, squinting, etc.) were recorded daily until euthanasia. To examine preexisting immunity, 5 groups (n = 4/sex) were infected intranasally (as described above) with the SCV2 Washington strain. At 28 dpi, each group was then infected with another variant (as described above) and euthanized at 35 dpi (post-original infection). BW and clinical scores as above were collected on 1-10, 14, 21, and 28-35 dpi. Results were analyzed by ANOVA and t-test; P < 0.05. Male and female hamsters lost significant amounts of BW, with males losing more weight than females. The BW loss over time differed significantly between most variant groups, with variants having up to a 13.9% difference in average weight loss on d 7. Hamsters with preexisting immunity lost significantly less BW than those without, with up to a 16.9% difference seen on 7 dpi. Unkempt hair, pinned ears, and squinting were the 3 primary clinical signs recorded, and no respiratory clinical signs were observed. Histologic findings revealed mild to severe lung consolidation, atypical type II pneumocyte hyperplasia, and macrophage infiltration, with severity dependent on the timepoint. In conclusion, prior SCV2 infection provided some protection against another variant. Future studies are warranted to investigate the pathogenesis of other variants and the molecular and immunological mechanisms of preexisting immunity. PS55 Physical Performance Is Enhanced in Old Mice Fed a Short-term Diet Medicated with Rapamycin, Acarbose, and Phenylbutyrate M Ellis*, W Ladiges, Z Jiang Comparative Medicine, University of Washington, Seattle, WA Loss of physical performance, as seen in humans by decreased grip strength and overall physical fitness, is generally accepted to be a consequence of aging. Treatments to delay or reduce these changes or increase resilience to them are generally not available. We are suggesting the use of a novel diet combination to increase resilience to age-related physical decline in mice. In this preliminary study, 20-mo-old male and female C57BL/6 mice were given either a standard mouse diet or a formulated mouse diet containing rapamycin (14 ppm), acarbose (1000 ppm), and phenylbutyrate (1000 ppm), or a diet containing one half dose of each drug, for 3 mo. Ten to 12 mice were included in each group. The rationale for the drug cocktail was based on validated anti-aging effects of the individual drugs, each targeting different but overlapping processes of aging. Rapamycin downregulates mTOR and acarbose increases glucoregulatory control, both working on different aging pathways to increasing lifespan in mice. Phenylbutyrate, an ammonia scavenger, enhances physical and cognitive performance in aged mice. At the end of the study, performance on a rotarod and grip strength test was compared. In general, mice fed the full dose drug cocktail diet performed better on these assays, with significant improvements in rotarod performance in females fed the full dose cocktail and in grip strength in males fed the full dose cocktail, and females fed the low dose cocktail. These observations provide support for the concept that short term treatment with a cocktail of drugs that targets multiple aging pathways can increase resilience to aging and suggests that this prototype cocktail could be part of a clinical therapeutic strategy for delaying age-related loss of physical performance in people.

Freund’s adjuvants are commonly used to boost polyclonal antibody production in rabbits, however, the immunostimulatory effects, in particular with complete Freund’s adjuvant (CFA), result in inflammation and can have the potential to cause pain and/or distress. Recommended injection routes for Freund’s adjuvants include subcutaneous and intradermal but there is still debate on which is the best in terms of animal welfare. It has been previously shown that subcutaneous administration of Freund’s adjuvant in conjunction with carprofen did not alter polyclonal antibody production in rabbits. However, no one has specifically looked at antibody titers after intradermal injection of Freund’s adjuvant along with nonsteroidal antiinflammatory administration. In this study, 9 female New Zealand White rabbits were assigned to 1 of 3 groups: intradermal inoculation with carprofen (4 mg/kg SC SID for 3 d; n = 3), intradermal inoculation with carprofen (4 mg/ kg SC SID for 3 d; n = 3), or subcutaneous inoculation without carprofen (n = 3). They were then immunized with antigen in CFA twice, 3 wk apart, followed by injection with antigen in IFA (incomplete Freund’s adjuvant) 3 wk later. One wk after immunization with antigen in IFA, blood was collected for circulating antibody titers. Three wk later rabbits were given a booster immunization of antigen in IFA and additional blood samples were collected 1 wk later. Titers were determined using radiolabeled ligands in solution with dilution series of the serum from each rabbit after each bleed. Clinical assessment of the rabbits was performed using an ethogram score for 20 d post both CFA injections. We found that carprofen administration did not adversely affect antibody production in response to the antigen used in this study. Ethogram scores for rabbits with intradermal injections without carprofen trended higher than for rabbits with intradermal injections with carprofen. These results indicate that carprofen may reduce the associated pain and distress of rabbits being used for polyclonal antibody production while not adversely affecting titer levels. PS57 Stretch-induced Atrial Arrhythmia in Isolated Hearts of Aged C57BL/6 mice JA Cayton*1,2, Z Nourian2,1, M Lambert2,1, T Domeier1,2 Department of Pathobiology, University of Missouri, Columbia, MO; 2Medical Pharmacology and Physiology, University of Missouri, Columbia, MO 1

Atrial fibrillation (AF) is the most common sustained arrhythmia, and more than 2.7 million people are living with AF in the United States. The elderly are at greatest risk for AF with prevalence estimated at ~10% in individuals over the age of 80. The aged myocardium is subjected to chronic stretch, and atrial muscle stretch is an established risk factor for atrial arrhythmogenesis. We hypothesized that increases in left-atrial pressure lead to atrial arrhythmogenesis in a mouse model of advancing age. To test this hypothesis, we used isolated hearts (excised hearts in a modified Langendorff perfusion technique) of aged (19-28 mo) C57BL/6 male (n = 6) and female (n = 2) mice subjected to atrial preloads of 0 cm and 12 cmH20 (i.e., increasing stretch). Atrial arrhythmias were monitored using left-atrial placement of an intracardiac electrocardiogram, and burst pacing stimuli were used to induce arrhythmias (bursts 2 s in duration with 20-40 ms varying cycle length, followed by a 3-min stabilization/observation

period, repeated 4 times). Arrhythmias were defined as transient (premature atrial contractions and salvos of <3 premature atrial contractions) or sustained (salvos of >3 premature atrial contractions, atrial tachycardia, or AF). At 0 cmH20 transient atrial arrhythmias were observed in 6/8 hearts, and sustained atrial arrhythmias were observed in 2/8 hearts. Following elevation in left-atrial preload to 12 cmH20 pressure, transient atrial arrhythmias were observed in 7/8 hearts and sustained atrial arrhythmias observed in 6/8 hearts (P < 0.05 versus 0 cmH20, z-test of proportions). Stretch-induced sustained atrial arrhythmias were observed in both male (4/6) and female (2/2) aged mice. In conclusion, the aged mouse atrium exhibits sustained arrhythmia in response to increases in left-atrial preload pressure. The aged C57BL/6 mouse model may therefore be useful for preclinical studies of age- and stretch-induced atrial arrhythmias. PS58 Hemodynamic Changes in Response to Hyperacute Spinal Trauma in an in Vivo Porcine Model of Spinal Reconstruction ED Barras*1, CD Hampton2, C Takawira1, T Taguchi1, A Nourbakhsh3, M Lopez1 Veterinary Clinical Sciences, Louisiana State University School of Veterinary Medicine, Baton Rouge, LA; 2Large Animal Clinical Sciences, The University of Tennessee College of Veterinary Medicine, Knoxville, TN; 3Spine Surgery Division Orthopedics Department, WellStar Atlanta Medical Center, Atlanta, GA 1

Acute spinal cord injury (ASCI) is a devastating event that can lead to severe hemodynamic consequences that vary with injury location and severity. The hemodynamic and metabolic changes that occur post- ASCI at the cervical and high thoracic region have been reported, but there is comparably little information about the hyperacute changes that follow low-thoracic ASCI. We sought to quantify the hyper-acute hemodynamic changes observed following ASCI using subjects as their own control. Six Yucatan gilts (44.2 ± 7.5 kg and 287 ± 4-d-old) were anesthetized, and a dorsal laminectomy performed at T10-T12. Standardized blunt trauma was applied for 5 consecutive m, and hemodynamic variables and arterial blood gas samples were collected before and after ASCI at regular intervals up to 240-m post-ASCI. Data was analyzed with a mixed effects model, and significance set at P < 0.05. Diastolic, mean, and systolic arterial pressures were significantly decreased 2 m post-ASCI by 18.2% (P = 0.0468), 16.1% (P = 0.0215), and 14.7% (P = 0.0085), respectively. Arterial pressures were diminished compared to baseline at 80 and 120 m post-ASCI, although they were within the physiologic range. A compensatory increase in heart rate was seen post-ASCI, but the change did not reach statistical significance. Blood glucose progressively increased post-ASCI, reaching a 50.3% (P = 0.0025) increment from baseline between 120 and 240 m post-ASCI. Together the results indicate that low-thoracic ASCI caused a consistent but clinically minor hyper-acute decrease in arterial pressures which did not produce hypotension or metabolic changes in Yucatan gilts. When employing this T10-T12 porcine ASCI model, pre-ASCI mean arterial pressures should be maintained above 75 mm Hg to avoid hypotensive states.

PS59 Low-stress Handling Techniques for Mice And Rats: Attitudes and Perceived Barriers of Implementation Among Animal Research Professionals C O’Malley*1, R Hubley1, C Moody2, PV Turner1,3 Global Animal Welfare and Training, Charles River Laboratories, Wilmington, MA; 2UC Davis, Davis, CA; 3University of Guelph, Guelph, , Canada 1

Promoting positive human-animal interactions by using lowstress handling (LSH) techniques can reduce potential animal fear and stress and improve study data, but uptake of these techniques has been slow for mice and rats in North America. We sought to understand attitudes towards and impediments of using LSH with mice and rats. Interviews were conducted with 40 participants from the US and Canada, including veterinary and animal science professionals (group 1; n = 17) and in-life technicians (group 2; n = 23). Participants were asked a series of open-ended questions as well as reviewing videos of techniques being discussed such as gentle handling, habituation, and positive reinforcement. The interviews were transcribed and qualitative software, NVIVO, was used to identify themes in responses. Reduced stress (52.5%), better data (42.5%), and improved welfare (40.0%) were identified as benefits of using LSH techniques. While 50% of participants had no concerns with using LSH, US participants were more likely to mention concerns, including researcher attitudes, training personnel, and time, while Canadian participants were most concerned with training of personnel. Generally, Canadian participants were more supportive of using LSH, and some indicated that they were already using these techniques. When asked how using LSH techniques would impact their job, most participants, regardless of demographics, believed they would have improved job satisfaction, decreased stress and/ or an easier job, but also increased time would be needed for training personnel. Respondents from all demographics (90%) indicated that implementing LSH would be worthwhile and would improve rodent welfare. Researcher attitudes were a perceived barrier for implementing LSH (22.5% indicating researchers would resist, and 55.0% indicating a variable researcher response). In general, research animal professionals in both Canada and the US recognized the welfare benefits that could result from more widespread adoption of LSH techniques for rodents at their institution. Addressing concerns about researcher attitudes through surveys or educational programs could be an important step for implementing LSH techniques with mice and rats. PS60 Self-assessment Tools to Support Research Groups and Institutions to Track, Evaluate, and Benchmark 3Rs Activities J Eddy*, V Robinson, MJ Prescott National Centre for the Replacement, Refinement and Reduction of Animals in Research, London, United Kingdom Obtaining a realistic evaluation of 3Rs activities is essential for researchers and organizations seeking to assess or improve their 3Rs culture as part of their animal care and use program. We have recently launched 2 3Rs self-assessment tools, 1 for research groups and 1 for research institutions. These are freeto-use, secure, interactive, online resources that are designed to allow the user to track, evaluate, and benchmark their 3Rs activities over time. Both consist of a series of questions on the 3Rs, developed in consultation with the scientific community and divided into thematic categories representative of the breadth of 3Rs-related activities that can be undertaken by a research group or institution. Once a question set is completed online, the system scores the responses and provides bespoke feedback on

126

how improvements can be made to further support 3Rs implementation. There are a number of benefits to using the tools. Scores can be used internally to allocate resource and effort, and to focus discussions at research group meetings or in the IACUC towards the most important areas and topics. The feedback gives useful advice and examples, helping to ensure that subsequent 3Rs efforts are successful. The 3Rs self-assessment can be repeated periodically and the results compared longitudinally, allowing progress to be tracked. Finally, scores can be used externally (e.g. in grant proposals and animal study protocols; or as part of discussions with regulatory bodies or the general public). Overall, use of the self-assessment tools will encourage a more active 3Rs culture and assist in delivering on commitments to the 3Rs. This talk will introduce the tools, outline the benefits to using them and guide people through the process of submitting a self-assessment. PS61 Creating a Digital Escape Room to Engage Technicians in Pursuit of Certifications BA Skiles*1, J DenHerder2 Laboratory Animal Resource Center, Indiana University School of Medicine, Indianapolis, IN; 2Office of the Campus Veterinarian, Washington State University, Pullman, WA 1

Preparing for a certification exam can be a daunting task for many adult learners. To encourage animal care staff to pursue AALAS certification, we have implemented prep courses at our respective institutions. The students come from a variety of backgrounds and have different study skillsets, test experiences, and learning styles. As teachers, we aim to address individual learning needs by using a variety of different methods to deliver the information, check for understanding, and assess the learning process. We recently discovered digital escape rooms and thought they could be an engaging way to reinforce learning and review training session information for technician certification courses. Digital escape rooms are increasingly being used by educators to add excitement to the learning process, which makes the content more memorable. Escape rooms present a scenario in which participants are “locked in” and cannot escape until they obtain the key. They do this by searching for clues and solving puzzles. We created completely digital escape rooms using an online file storage and document creation platform. Puzzles were created or adapted to review and reinforce content from the technician certification manual and workbook, and then “hidden” in the virtual escape room with clues. Participants used the information learned in class or from their reading to solve the puzzles and escape the room. We discuss our successes and challenges using this tool as a review activity for technician certification courses. PS62 Transparent Communication and Failure Management In Animal Research SJ Bischoff*, A Enkelmann Animal Welfare, University Hospital Jena, Jena, , Germany The strong need for a culture of care has now extended into animal research worldwide. Many of these care programs confirm animal research institutions’ commitment to high standards of animal care and to obtaining reproducible, excellent scientific data. However, reports about negative results gained from these experiments, which is essential for the progress of biomedical science, are rarely published. Consequently, animal research often lacks transparency and reflection of failure or stakeholders are burdened with feelings of guilt and fear of

PS63 Planning a Successful Employee Engagement Program for a Remote Work Setting KL Cavanaugh*, SL Pritt IACUC, University of Texas Southwestern Medical Center, Dallas, TX With the dawn of COVID-19, many IACUC offices transitioned to working remotely and even in the wake of the pandemic, many are electing to stay either partially or fully remote. Without a shared workspace, how do you keep staff engaged and foster office morale? To address this question, we developed several unique engagement strategies. First, office leadership designated one of its managers to spearhead the engagement efforts. By centralizing the responsibility, it facilitated an organized approach to planning the engagement initiative. Next, the staff were surveyed on 2 key areas: what type of virtual events they want to participate in and how often they want these events to occur. Using the results, the engagement manager planned consistently scheduled and diversified events to appeal to the expressed interests of the staff. These events ranged from social in nature to professional development driven. For instance, one event was a tour of a local llama farm, while the next was a department wide training on emotional intelligence. Soliciting the participation of staff in the planning phase allows them to feel engaged throughout the process, from design to execution. Some staff expressed a preference for more passive engagement resources (rather than events), particularly an office newsletter. Now, one year after its debut, the newsletter is prepared by rotating staff members to feature department updates, articles of interest, and personal anecdotes. Another engagement strategy deployed was to introduce conversational icebreakers at the start of each staff meeting. This was a creative way to utilize an existing group meeting and leverage it to boost engagement and build comradery. The meeting is also used to dole out employee recognition by publicly highlighting staff accomplishments and exceptional work. At the end of the year, the engagement manager composes a highlight reel of these accomplishments and the video is posted on the department’s webpage. Planning a successful engagement program starts with listening to the desires of the staff, delivering diversified events and resources customized to their interests, and showing ongoing recognition of their achievements.

PS64 Extending the Use of Exposed Vascular Access Ports in Miniature Swine E Callahan*, A Wakefield, M Haney Veterinary Services, Sinclair Research Center, Columbia, MO Jugular vein vascular access ports (VAPs) are commonly implanted to allow for repeated intravenous access in miniature swine. A potential complication is erosion of the port chamber through the skin, resulting in port exposure. This requires removal of the VAP to prevent further complications, such as infection. Port removal often results in the animal’s premature removal from study. The purpose of this study was to determine the efficacy of relocating exposed VAPs to a new subcutaneous (SC) position in castrated male, miniature swine to allow continuation on study. Miniswine (n = 30) with exposed VAPs underwent surgical relocation. The animals were anesthetized, intubated, and maintained on isoflurane throughout the procedure. Ketoprofen and enrofloxacin were administered intramuscularly prior to the procedure for analgesia and antibacterial prophylaxis, respectively. The site was aseptically prepared and an incision was made ~2cm cranial or caudal from the exposed VAP. A new SC pocket was created, and extended toward the exposed port. The VAP was removed through the incision, and a new sterile VAP head was placed on the intact catheter, and secured in the new pocket. The incision site was flushed with povidone solution prior to closing and closed with absorbable suture. The previous site was left open to heal by second intention. Relocation was considered a success if the VAP was functional, not noticeably infected, and not re-exposed at least 90 d after relocation. Of the 30 VAPs that were relocated, 18 met the success criteria (60% success rate). Four VAPs were noted to still be functional over 300 d after relocation. Complications contributing to failed VAP relocations included surgical site infection and repeated exposure. With a 60% success rate, relocation is a viable treatment option for exposed VAPs. This leads to longer animal retention on study, allowing more information to be obtained from individual animals. VAP relocation requires considerably less time, materials, and effort than implanting a new VAP in additional animals. Thus, VAP relocation has the potential to decrease costs and reduce animal numbers required for long-term studies, and improves data quality by enabling the continuity of individual animals on their respective studies. PS65 Effects of Housing and Research Conditions on Ethogram and Indices of Behavioral Welfare in Rhesus Macaques (Macaca mulatta) KR Lambert*, EL Mitchell, M Leblanc ARP, Wake Forest University, Winston-Salem, NC Understanding the influence of housing and research on behavior of Rhesus macaques is essential to improve their welfare. We sought to characterize the prevalence of abnormal behaviors in adult Rhesus (n = 293) of Indian (IND) or Chinese (CHI) descent enrolled in neuroscience (NEU) and non-neuroscience (NNEU) research. Animals were housed singly (36%) or socially (64%) in cages (49%) or pens (51%). Overall, 66% of animals had behavioral consultations (BC) for abnormal behaviors. Common reasons for BC were alopecia (AL, 53%), stereotypia (STY, 26%) and self-directed behavior (SDB, 7.5%). Special consideration plans (SCP) to address abnormal behaviors were developed for 45% of the population. The probabilities of requiring BC or SCP were not influenced by sex, housing (pen/rack), or descent (IND/CHI) but BC and AL animals were older. Macaques housed socially had a higher probability of needing BC or displaying AL as compared to

allegations. In order to follow the openness concept in animal research, procedural failures can be used as learning and animal welfare improvement opportunities. Sharing negative results gained from animal experiments can be seen as an evolutionary process requiring years to fully develop. The web-based platform CIRS-LAS (Critical Incident Reporting System in Laboratory Animal Science) helps scientists to reflect on negative results originating from well-designed preclinical studies. CIRS-LAS platform is gaining worldwide recognition from researchers for enabling constructive dialogue about possible causes of animal experiment failures as well as possible solutions. Incident reports mainly refer to complex laboratory animal models such as orthopedics (24%), anesthesiology (20%), and cardiovascular research (13%). The positive publication landscape trend towards a culture of care leads recognizing the high scientific value of negative results publication and critical incident reporting on CIRS-LAS.de - both increase the transparent communication in animal research. Subsequently, this effort may save animal lives and prevent unnecessary repetition of unsuccessful experiments, wastage of funds, and delay in scientific progress.

single housing. When considering research, single housing had a negative behavioral effect in monkeys enrolled in NEU (increased BC, AL, STY) while social housing correlated with increased BC and AL in NNEU animals. These findings suggest that the impact of social housing on behavior vary based on research conditions. We also assessed the effects of sex, age, descent, housing, and research on an ethogram of 16 behaviors. In time spent, the most common behaviors were categorized as exploratory (EXP, 29%), inactivity (IA, 29%), stereotypia (STY, 12%), foraging (FOR, 11%) and self-manipulation (SMP, 8.0%). Females displayed more EXP while males showed more IA, FOR, and SMP. CHI macaques showed more EXP and less FOR than IND. Pen-housed animals spent more time in STY than those in cages. Socially housed animals spent more time in EXP behaviors and less time showing IA and SMP as compared to single housing. Macaques enrolled in NEU research spent less time EXP and more time SMP than those enrolled in NNEU. Singly housed animals enrolled in NEU foraged less as compared to those group housed, confirming that single housing in NEU is correlated with negative indices of welfare. In conclusion, age, sex, descent and housing conditions affect normal and abnormal behaviors but these effects vary based on the research program in which animals are enrolled. PS66 Cross-facility Collaboration to Develop a Novel Welfare Assessment Tool for Research Primates E Paterson*1, PV Turner1,2 Pathobiology, University of Guelph, Guelph, , Canada; 2Global Animal Welfare and Training, Charles River, Wilmington, MA 1

Formally assessing the welfare of large numbers of animals can be challenging but is needed to ensure evidence-based decision-making for improving animal care and use programs. In other fields of captive animal management, such as agriculture and zoos, animal welfare frameworks and welfare assessment grids have been developed for this purpose, but no such tool exists for different species of research animals. When developing robust animal behavioral management programs, facilities should conduct periodic animal welfare assessments to support continuous program improvements and build institutional awareness of areas requiring more attention. This multifacility, collaborative project aimed to develop a novel primate welfare assessment tool (PWAT). The PWAT development involved (1) establishing an internal working group of primate behavior experts; (2) identifying main animal welfare categories and descriptors based on a literature review; (3) development of a preliminary tool; (4) beta testing the tool across facilities (6 facilities located in Canada, USA, and the EU) to ensure practicality and final consensus; (5) development of a finalized tool with automated data analysis; and (6) roll-out to 13 sites for benchmarking welfare scores for future use. The tool assesses different outcome and input-based measures of the behavioural management program as well as overall institutional culture of care using 6 different categories: physical, behavioural, training, environmental, procedural, and culture of care, and containing 167 descriptors. Measures were weighted based on assessed welfare impact and response types included nominal (yes/no) and numerical (0,1,2) values. Following initial benchmarking, the tool will be used to assess changes in the behavioral management program over time. The development process of the PWAT demonstrates that evidence-based assessment tools can be developed in practices through collaboration and consensus. The process is important for uptake across sites as well as for development of other welfare assessment tools for other research species.

PS67 Investigation of Cynomolgus Macaque Nocturnal Behavior Before and Following Surgery: Considerations for Postoperative Care and Management E Paterson*1, PV Turner1,2 Pathobiology, University of Guelph, Guelph, , Canada; 2Global Animal Welfare and Training, Charles River, Wilmington, MA 1

Sleep ensures good physical and mental health through interconnected immunologic, physiologic, and neurologic signaling pathways. In human medicine, a bidirectional correlation is seen between sleep quality and pain. Further, even when robust pain management protocols are provided postoperatively, human patients often report experiencing breakthrough discomfort/ pain in the night. This suggests that efforts should be made to better understand and create a comfortable environment for research animals undergoing surgery to minimize discomfort and improve their rest. Research primates spend 50% of each day in a dark phase and there is limited research on their behavior during this time. This study examined dark cycle behavior of cynomolgus macaques before and following surgery to provide insight into their needs to ensure optimal recovery conditions. We hypothesized that nocturnal social interactions between familiar conspecifics, such as huddling, would be used to provide comfort and optimize thermoregulation and that increased restlessness in the postoperative nocturnal period might be seen with breakthrough pain or discomfort despite the use of multimodal analgesia. Cynomolgus macaques (n = 43) underwent routine telemetry instrumentation surgery and were treated perioperatively with buprenorphine (0.3mg/mL/animal) or buprenorphine slow release (0.2 mg/kg), injectable meloxicam (0.2 mg/kg) and oral meloxicam (0.1 mg/kg) and bupivacaine (0.25%, 0.5mL) or 50:50 bupivacaine and lidocaine (0.25%, 20mg/mL) and were video recorded 12 h before and after surgery during the dark phase. Sampling intervals of 15 min/h were used and 123 h of video was scored by an observer blinded to time, interval, and animal using a detailed ethogram. Results demonstrated a 21% increase in animal activity in the postoperative period. For social interactions, 92% and 76% of the dark phase was spent huddling pre vs postoperatively, respectively. These results suggest that breakthrough pain/discomfort may occur in the dark phase in research primates despite robust analgesic use, recognized by increased restlessness, and also emphasize the importance of maintaining social housing of familiar research primates for increasing postoperative comfort. PS68 Will Rhesus Macaques (Macaca mulatta) Meet Standard Awake-behaving Performance Levels in a Neuro Study without Food or Water Restriction? A Refinement Reviewed A Sorrells*, K Thurman, M Vogel Neuro Behavior, Neuralink, Daly City, CA While the field of behavioral neuroscience continues to advance prolifically, the methods for obtaining data from research animals remain consistent with practices developed in previous decades. Standard practices may include water or food restriction to motivate desired behavior in neuroscientific studies. These strategies require strict oversight by lab staff, veterinarians, and IACUC to mitigate the potential risks posed to the animal’s well-being. Less restrictive approaches are being examined for ability to meet similar quality and quantity of data output. Our objective is to replace a standard water restriction protocol with a novel food rescheduling program that uses a variety of foods and meets the Maintenance Energetic Requirement of each animal to motivate desired behavior.

PS69 Efficacy of Oral Cannabidiol in a Guinea Pig Model of Primary Osteoarthritis AP Spittler*1, M Sadar2, J Helbling1, K Patton1, K Lee1, J Becker1, M Sykes1, J Grubb1, S McGrath2, D Gustafson2, KS Santangelo1 Microbiology, Immunology, and Pathology, Colorado State University, Erie, CO; 2Clinical Sciences, Colorado State University, Fort Collins, CO 1

Osteoarthritis (OA) is a degenerative joint disease that commonly causes decreased and painful mobility. Due to a lack of safe and effective treatments, many individuals are seeking alternative therapeutics for discomfort. Cannabidiol (CBD), the non-psychotropic component of the cannabis plant, has gained popularity as an OA treatment due to its anti-inflammatory effects. However, there is minimal evidence regarding its efficacy for OA. The aims of this study were to assess the ability of oral CBD to prevent the structural onset and/or progression of OA and determine its efficacy for symptom modification. The Hartley guinea pig spontaneously develops OA at 3 mo of age, serving as a model for nontraumatic OA in humans. Twenty-four, 2-mo-old male guinea pigs were randomly assigned to receive 50 mg/kg CBD (n = 8), 100 mg/kg CBD (n = 8), or vehicle control oil (n = 8) twice daily for 3 mo. Treadmill-based gait analysis, overhead enclosure monitoring, and pressure sensor analysis were performed bi-weekly. At 5 mo of age, guinea pigs were euthanized to collect blood for hematology and biochemistry and knee joint tissues for histopathology. There were no clinically significant differences in weight, femur length, hematology and biochemistry, or gait/mobility between groups. Grossly, the integrity and thickness of knee joint articular cartilage was maintained in the 100 mg/kg CBD group compared to 50 mg/kg CBD and vehicle control groups. Higher concentrations of CBD and/or longer treatment duration may be needed to improve OA-related symptoms in this animal model. PS70 Site-specific Effects of Anterior Cruciate Ligament Transection on Post-Traumatic Osteoarthritis Development in a Rabbit Model Y Carcamo*1, R Terracciano1,2, A Royal1, JD Harris3, BK Weiner3, JS Labis4, N Gupta4, CS Filgueira1,5 Nanomedicine, Houston Methodist Research Institute, Houston, TX; 2Electronics and Telecommunications, Politecnico di Torino, Torino, Italy; 3Orthopedic Surgery, Houston Methodist Research Institute, Houston, TX; 4Clinical Radiology, Houston Methodist Re1

search Institute, Houston, TX; 5Cardiovascular Surgery, Houston Methodist Research Institute, Houston, TX A tear of the anterior cruciate ligament (ACL), a common injury in physically active individuals, is the most well-known risk factor for developing post-traumatic osteoarthritis (PTOA). Unfortunately, there is no single measure for PTOA diagnosis and no medical therapies have been shown to halt or slow its progression. Identifying early changes in articular cartilage due to ACL injury in a translationally relevant animal model is beneficial for establishing when clinical intervention should occur. To determine a treatment window, we transected the ACL in the right stifle joint of 5 female skeletally mature New Zealand White rabbits (Oryctolagus cuniculus, age 7.7 mo, weight 3.56±0.11 kg), where the contralateral knee provided an experimental control. Up to 10 wk post-surgery, we imaged the rabbits biweekly using 7T magnetic resonance imaging (MRI) to noninvasively develop a timeline of PTOA progression. For each imaging session, they were sedated via IM injection of ketamine (50 mg/kg) and midazolam (1 mg/kg) into the epaxials, intubated, and maintained with isoflurane via mechanical ventilation and monitored. After sacrifice, the femur, tibia, and patella from both knees were harvested and imaged using micro-computed tomography (microCT) to check for osteophytes, a characteristic of arthritis. The femoral cartilage was sectioned, stained with Safranin-O and Fast Green to evaluate proteoglycan content and cartilage thickness. MR imaging indicated a significant decrease in T1 values over time compared to the control, suggesting lower glycosaminoglycan content resulting from progressive cartilage degradation. MicroCT imaging showed osteophytes in the transected joints, which were not present in the controls. Safranin-O/Fast Green histology showed a decrease proteoglycan content and cartilage thickness. We found that the effects of ACL transection in rabbits 10 wk post-surgery are site-specific as evident by MRI, microCT, and histology. Significantly, we were able to demonstrate use of 7T MRI and obtain quantitative T1 maps in less than 30 min to assess PTOA progression in rabbits, which are highly sensitive to anesthesia and extended sedations. This study forms the basis of future work to develop a therapeutic strategy to halt PTOA progression. PS71 Antibiotic Management of Corynebacterium bovis Associated Clinical Disease for NSG Mice CA Manuel*1,3, U Pugazhenthi2, M Fink1,3, L Habenicht1,3, DL Fong1,3, JK Leszczynski1,3, MJ Schurr4 Office of Laboratory Animal Resources, University of Colorado Denver, Aurora, CO; 2Division of Endocrinology, Metabolism and Diabetes, University of Colorado Anschutz Medical Campus, Aurora, CO; 3Department of Pathology, University of Colorado Anschutz Medical Campus, Aurora, CO; 4Department of Immunology and Microbiology, University of Colorado Anschutz Medical Campus, Aurora, CO 1

Due to the difficulty in eliminating Corynebacterium bovis from immunodeficient mouse colonies, infected mice must sometimes be tolerated during remediation efforts with the ultimate goal of agent eradiation. Efficacy of therapeutic antibiotics on C. bovis clinical signs in NSG (NOD.Cg-PrkdcscidIl2rgtm1Wjl/SzJ) mice has never been investigated. We hypothesized that oral-amoxicillin can decrease C. bovis clinical signs in infected NSG mice. Unlike athymic nude mice, C. bovis clinical signs in NSG mice does not spontaneously resolve. Naïve, 7-wk-old, female NSG mice (n = 14) were exposed to both soiled bedding and NSG mice with C. bovis

formance, we collected data on the following metrics in 6 of our lab’s male macaque monkeys: trial count, bitrate, and duration of attention to research task, as well as latencies to enter chair, head immobilization, and participation. This data was compared to results of a survey distributed amongst 20 anonymous behavioral neuroscience labs. We hypothesized that macaques under less restrictive protocols would take significantly less time to enter chairs, allow head mobilization, and begin participating in the research task than those of labs utilizing water restriction alone. We further hypothesized that macaques would accomplish similar trial counts per hour and bitrates regardless of training protocol. Both approaches require similar labor efforts and documentation for success. Anecdotal results suggest that this less restrictive approach may be successfully used to obtain high quality data without the challenges posed to animal welfare associated with restriction protocols. By ensuring their basic needs are met, the animals’ opportunity to voluntarily participate better mimics comparable human trials. This allows the data to meet standards of translational science.

clinical signs and then confirmed positive by PCR. Five wk post inoculation (PI), at the clear presence of clinical signs, mice were either maintained as untreated controls (n = 6), or treated with amoxicillin in the water (0.26 mg/mL) for 3 wk (n = 8). Antibiotics were then either discontinued (n = 4) to assess return of clinical signs or continued (n = 4) to determine the point of complete clinical resolution. Mice were weighed and scored weekly, using 6 clinical parameters where the sum of the scores ranged from 4-18 were 4 is normal and 18 is considered clinically severe. At 5 wk PI, the mean clinical score (MCS) for the untreated controls and mice to-be-treated were 11.8 ± 0.7 and 12.4 ± 1.5, respectively. At 8 wk PI, the MCS was 17.3 ± 1.5 for untreated controls and 5.5 ± 1.0 following 3 wk of amoxicillin (P ≤ 0.001). Use of amoxicillin demonstrated a clear clinical improvement, including body weight gain after 1 wk of treatment. For the mice where antibiotics were discontinued after 3 wk, clinical signs returned were the MCS was similar to untreated controls 6 wk (P = 0.9) after treatment discontinuation. Continuous amoxicillin for 6 wk was required to achieve complete clinical resolution. For NSG mice, amoxicillin can be used to reduce or eliminate clinical signs while being administered. However, once discontinued, clinical signs reoccur, confirming a failure to eliminate the infection. Antibiotic stewardship should be considered with prolonged use for the control of C. bovis infections and must not be considered a method of C. bovis eradication. PS72 Assessing Ambient Ultrasound and Vibration across Vivaria AJ Barabas*1, A Darbyshire2, S Schlegel2, BN Gaskill1 Animal Science, Purdue University, West Lafayette, IN; 2Laboratory Animal Program, Purdue University, West Lafayette, IN 1

Excessive noise and vibration are detrimental to rodent welfare, yet these parameters are not often recorded in vivaria. It is unknown if suggested thresholds are exceeded in most housing environments and which specific factors may alter these parameters. Therefore, this study aimed to identify how environmental factors may alter noise and vibration at the room and cage level. Measurements were taken with an ultrasonic microphone and accelerometer. Recordings in the room (n = 64, across 9 buildings) were taken in open air at a central location while recordings taken on an animal transfer station (n = 51) or ventilated rack (n = 94) were taken inside an empty mouse or rat cage containing chow, water, and bedding. For each transfer station and rack, the manufacture year was recorded along with the species and number of cages on the rack. At each location, a baseline measurement was taken, followed by one with the transfer station on. For racks, measurements were taken at the top, middle, and bottom row. Data were analyzed with general linear mixed models. Average noise intensity was higher in rat rooms while the transfer station was functioning, in both the cage placed on the transfer station (P < 0.001) and at the wider room level (P < 0.001). Noise was lower in newer ventilated racks, but only when the transfer station was off in the room (P < 0.001). Within a cage on a rack, noise was also higher at the top when the station was on (P = 0.024), and was lower when the rack had more cages (P < 0.001). Average vibration was not impacted at the room level. On the transfer station, vibration was higher when it was on (P < 0.001). On the rack, however, vibration was lower in newer models (P < 0.001), decreased with row height (P < 0.001) and number of cages on the rack (P < 0.001). Although differences were found, the suggested vibration threshold was never met. However, the noise threshold was exceeded in rat rooms with the transfer station on.

The severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) has infected more than 170 million individuals and claimed 3.5 million lives as of June 1, 2021. SARS-CoV-2 infects host cells by the binding of its spike protein to the cellular surface protein angiotensin-converting enzyme 2 (ACE2). Unlike human ACE2, mouse and rat Ace2 proteins cannot efficiently mediate the SARS-CoV-2 infection. Therefore, wildtype mice and rats cannot be used for modeling the disease. Currently, the widely used mouse models for COVID-19 research are random transgenic models that artificially express human ACE2 under the control of cytokeratin 18 promoter or a constitutive promoter. While most of these mice show some COVID-19 phenotypes, none of those transgenic models fully recapitulate the disease course observed in COVID-19 patients. This is because the transgene promoter, integration site, and copy number in those models all differ from those of mouse Ace2 gene, and furthermore, the mouse endogenous Ace2 is still expressed. To overcome these limitations, we have developed humanized ACE2 mouse and rat models using CRISPR-Cas9. Specifically, we inserted a ~3kb human ACE2 cDNA cassette into the mouse and rat Ace2 gene loci to ensure that human ACE2 expression is under the control of rodent Ace2 promoter and regularity elements, while simultaneously disabling the rodent Ace2 gene. To do this, we first screened CRISPR gRNAs targeting close to the translation initiation site of Ace2 in cultured mouse and rat cells, then microinjected CRISPR/ Cas9 complex and donor DNA into 1-cell stage embryos. Founder animals were screened by junction PCR and insert PCR, and the PCR products were Sanger sequenced. Tissue samples were harvested from hemizygous or homozygous animals for expression analysis. RT-qPCR and Western blot analysis data show that, in our model, human ACE2 is expressed in tissues expressing endogenous Ace2 (such as lung, kidney, and GI tract), while rodent endogenous Ace2 is absent from these tissues. Further breeding data show both hemizygous and homozygous humanized ACE2 animals appear to be normal and fertile. In summary, these data suggest that our humanized ACE2 models can be valuable for COVID-19 research.

Materials derived from humans may be contaminated with human viruses. Cell lines and tumors that have been passaged in mice may have been previously exposed to rodent pathogens, therefore screening for these agents in human-derived samples is also relevant. To determine field prevalence, we compiled data for samples that were identified as human in origin between September 2011 and

PS75 MHV-1 and MHV-A59 Results in COVID-like Disease in A/J Mice JD Macy*1,2, SR Compton1, CJ Booth1 Comparative Medicine , Yale University, New Haven, CT; 2Yale Animal Resources Center, Yale University, New Haven, CT 1

Mouse hepatitis virus (MHV) is a natural betacoronavirus of mice with enterotropic and polytropic variants. To better understand the similarities of polytropic MHV pathology with COVID-19, the objective is to characterize the range of pathological lesions and host responses caused by 2 MHV strains with different virulence in the respiratory tract. Groups of 4 to 6 male and female A/J mice, were infected intranasally with 3 x 106 or 1 x 107 of MHV-A59, or 1.5 x 104 or 1.5 x 105 MHV-1 or media (controls; n = 2). Mice were euthanized, necropsied, and tissues were collected at 2-5 d post infection (DPI). All mice infected with MHV-A59 or -1 had significant weight loss with clinical signs of severe dehydration. Microscopically, mice had widespread pneumonia and fibrosis at 3-4 DPI. Viral titers correlated with lung pathology, with MHV-1 having consistent viral titers from 2-7 x 106 pfu/g of lung whereas viral titers were highly variable in mice infected with MHV-A59, ranging from undetectable to 6 x 107 pfu/g of lung. Lymphoid and hematopoietic tissues showed necrosis of lymphocytes in thymus, spleen, and lymph nodes and a 25-75% loss of bone marrow hematopoietic cells and 3-fold reduction in circulating lymphocytes in all infected mice. Gastritis and intestinal villus blunting were also present. Significant olfactory blub lesions included marked neuron pyknosis and variably edema in some mice infected with MHV-A59. Female mice infected with A59 developed severe acute hepatocellular necrosis on 3 DPI. Some mice had hypereosinophilic myocardiocytes (myocardial degeneration). MHV infection in A/J mice results in pulmonary, cardiac, brain, hepatic, hematopoietic, and gastrointestinal system disease mirroring the tissues affected by COVID-19.

PS76 MHV-1 Causes More Respiratory Disease than MHV-A59 in C57BL/6 and 129S1 Mice JD Macy*1,2, CJ Booth1, SR Compton1 Comparative Medicine , Yale University, New Haven, CT; 2Yale Animal Resources Center, Yale University, New Haven, CT 1

Mouse hepatitis virus (MHV) is a natural betacoronavirus of mice with enterotropic and polytropic variants. To better understand the similarities of polytropic MHV pathology with COVID-19, the objective is to characterize the range of pathological lesions and host responses caused by 2 MHV strains with different virulence in the respiratory tract. Groups of 4-12 male and female C57BL/6J (B6), 129S1/SvImJ (129) mice were infected intranasally with 3 x 106 or 1 x 107 of MHV-A59 , 1.5 x 104 or 1.5 x 105 MHV-1 or media (controls; n = 2). Mice were euthanized, necropsied, and tissues were collected at 4, 8, and 12 d post infection (DPI). B6 and 129 male and female mice infected with MHV-A59 or -1 had hepatic necrosis, hepatitis, olfactory bulb lesions, and lung lesions to varying degrees. Mice infected with MHV-A59 had more significant hepatic lesions compared to mice infected with MHV-1. Brain lesions resulting from MHV-A59 consisted of 1 or more of the following: shrunken neurons, dissolution of the neuropil, encephalitis, vasculitis, and/or meningitis. In contrast, significant brain lesions with MHV-1 occurred only at 8 DPI in B6 mice. Severe olfactory bulb lesions in 129 mice did not resolve by 12 DPI suggesting the potential for a long-term negative impact on olfaction. Mice infected with MHV-1 have more severe and widespread lung pathology compared to MHV-A59 infected mice and was characterized by alveolitis/pneumonia, fibrin deposition and alveolar protein persist through 12 DPI where up to 40% of the lung lobes were still affected. Viral titers in lungs of B6 mice infected with MHV-1 or -A59 on DPI 4 were variable ranging from undetectable to 2 x 106 pfu/g of lung. 129 mice infected with MHV-A59 had consistent viral titers between 3 x 104 and 2 x 105 pfu/g of lung on DPI 4. MHV was not detected in B6 and 129 mice infected with MHV-1 on DPI 8 whereas 25% B6 and all 129 mice infected with MHV-A59 had low viral titers (6 x 102 to 4 x 104 pfu/g of lung) on DPI 8. These results suggest that lung lesions persist beyond when MHV can be detected in the lung. MHV-1 is a better respiratory disease model in B6 and 129 mice than MHV-A59 because of its higher tropism for respiratory tissues and it has less impact on the brain and liver. PS77 Assessing Mouse Kidney Parvovirus Elimination from Cages by Mechanical Washing AL Carlson*1, RJ Ricart Arbona1, CL Perkins2, KS Henderson2, NS Lipman1 Memorial Sloan Kettering Cancer Center, New York, NY; 2Research Animal Diagnostic Services, Charles River Laboratories, Wilmington, MA 1

Mouse Kidney Parvovirus (MKPV), a novel parvovirus of the new genus Chaphamaparvovirus, causes inclusion body nephropathy in severely immunocompromised mice and is prevalent in research mouse colonies. As non-enveloped viruses, well characterized parvoviruses of veterinary importance including canine parvovirus, feline panleukopenia virus, and murine parvovirus (MPV), which are members of the Protoparvovirus genus, are stable and resist inactivation by elevated temperatures and disinfectants. As a novel and highly divergent parvovirus, the resistance of MKPV to thermal inactivation is unknown. The goal of this study was to examine the ability of a common cage sanitization method, washing in a mechanical washer, to eliminate MKPV. Cages which had previously housed MKPV-infected mice

December 2020. Only research biologic samples submitted for panel screening were included; samples tested for individual agents were excluded to prevent the introduction of inadvertent bias. Real-time PCR was performed using proprietary assays and positive results were demonstrated to be reproducible. PCR was performed using panels testing up to 20 human viruses. The prevalence of each agent was calculated based on the total number of tests for that agent. For human viruses, Epstein-Barr virus was the most prevalent at 3.18%, followed by Herpesvirus type 7 at 2.36%, Human Immunodeficiency-virus type 1 at 0.98%, Herpesvirus type 6 at 0.72%, Human papilloma virus type 18 at 0.43%, AAV-2 at 0.28%, Human papilloma virus type 16 at 0.23%, and Hepatitis B virus at 0.19%. Eight additional human viruses were detected with prevalence <0.1%. Rodent panels contained PCR assays for up to 28 individual agents, including both viruses and bacteria. Mycoplasma was most prevalent at 5.59%, followed by C. bovis at 2.81%, and LDV at 1.60%, respectively. Murine norovirus, mouse parvovirus, polyoma virus, and Sendai virus were all detected at a prevalence of <0.1%. Although not yet detected in research biologics by our laboratory, murine chapparvovirus, a newly identified and prevalent agent in many animal facilities, should be a consideration for screening tumor cell lines. The impact and/or prevalence of many of these human and rodent infectious agents highlights the need to perform quarantine testing of any research biologic prior to its release for use.

were assigned to 1 of 3 groups: sanitization in a tunnel washer without chemical detergent (82.2°C (180oF) final rinse for 20 s; n = 10); sanitization in a tunnel washer followed by autoclave sterilization (121°C for 20 m; n = 10); or, control (bedding change only; n = 10). The presence of MKPV on the cage was assessed by PCR performed on swabs collected from the cage interior prior to group assignments and again after treatment. After treatment, 4 MKPV-negative CD-1 female mice were housed in each cage. The processes above were repeated so that each group of CD1 mice was housed in a cage from the same treatment group at the initiation of the study and again 14 later. Twelve, 17, and 20 wk after the first exposure, 1 mouse per cage was sacrificed and renal tissue submitted for MKPV PCR. MKPV was detected by PCR in 63% of pre-treatment soiled cages. All cages sanitized in a tunnel washer +/- sterilization were PCR negative after treatment. Three of 10 (30%) mice in the bedding dump group were renal MKPV PCR positive at 12 wk post-exposure. The number of PCR positive mice housed in these cages doubled (6 of 10) at >17 wk post-housing. No mice (n = 40) housed in cages sanitized in a tunnel washer +/- sterilization tested positive for MKPV at any time point. This study indicates that MKPV contaminated caging can result in MKPV infection and use of a mechanical cage washer is sufficient to remove MKPV nucleic acid and prevent transmission to naïve mice. PS78 Nasal Swabs for Virus Quantification in a Syrian Hamster SARS-CoV-2 Model: A Novel Technique JJ Dearing*, S Caicedo, T Yellowhair, MS Vermillion, A Werts Physiology, Lovelace Biomedical Research Institute, Albuquerque, NM The Syrian Golden Hamster has emerged as a reliable small animal model of SARS-CoV-2 infection and disease. Intranasal inoculation of hamsters consistently results in high viral load in lung tissues, both aerosol and fecal shedding, and measurable clinical disease with successful recovery. Although this model has shown great utility for evaluating candidate vaccines and therapies, it can be optimized with focus on the 3Rs. The majority of published SARS-CoV-2 studies in hamsters include staggered necropsy dates for quantification of viral load from terminally collected respiratory tissues. Here we describe methods for inlife nasal swab collections that can be performed serially within the same animals to characterize upper respiratory tract (URT) viral replication across the study, allowing for the collection of more data with fewer animals. In this study, 12 male hamsters were inoculated intranasally with 101-104 TCID50 SARS-CoV-2 (3/ dose). Nasal swabs were performed 1, 3, and 5 d post-infection (DPI) using 0.5mm fiber tip applicators. SARS-CoV-2 genomic and subgenomic RNA was quantified by reverse transcriptase quantitative PCR (RT-qPCR). Clinical disease and body weights were measured daily. Animals were euthanized 8 DPI for lung weights and quantification of tissue viral load by RT-qPCR. All titers resulted in productive viral replication, mild weight loss, and pneumonia. Peak weight loss (6 DPI) was directly correlated with inoculation titer, indicating disease severity was dependent on inoculation dose. In nasal swabs, peak viral replication occurred 1 DPI in animals inoculated with 102-104 TCID50, and 3 DPI in animals inoculated with 101 TCID50. By 5 DPI, viral load in nasal swabs was similar in all groups. Lung:body weight ratios measured 8 DPI were significantly higher in animals dosed with 104 TCID50 as compared to other groups despite no difference in viral load in lung tissue. In summary, these data support collection of nasal swabs as a surrogate for terminal tissue collections for quantification of viral load in the URT of SARS-CoV-2-infected hamsters.

This technique promotes the 3Rs by eliminating the need for staggered necropsies and allowing direct comparison of viral replication kinetics within each animal. PS79 Minimally Invasive Transthoracic Approach for Intrapleural Injection Improves Clinical and Research Outcomes Compared to Invasive Transabdominal Approach in a Mouse Model JJ Xu*1, NL Herndon1, M Lucero2, JL Ludwig1, J Chan2 Division of Animal Resources, University of Illinois at Urbana-Champaign, Urbana, IL; 2Chemistry, University of Illinois at Urbana-Champaign, Urbana, IL 1

Intrapleural injection of tumor cells in mice can be used to model malignant pleural disease in humans, deliver therapeutic agents, or trace neuronal pathways. Methods of intrapleural injection include a minimally invasive transthoracic injection (without surgical exposure), or a surgical exposure of either the diaphragm (via abdominal exposure) or thoracic wall (via extensive tissue dissection) to visualize the site prior to injection. While a minimally invasive approach without surgical exposure can be considered a refinement to a surgical approach, one potential drawback is the increased likelihood of an inexperienced surgeon creating an off-target effect during injection. In this pilot study, we hypothesized that a minimally invasive transthoracic approach (MI-TT) would have similar accuracy of injection into the pleural space as a surgical transabdominal approach (SX-TA), and result in improved clinical outcomes for the mice (decreased surgical time and complications). Prior to procedures, surgeons were trained in MI-TT and SX-TA approaches. Nude mice (female, 4–6-w-old, n = 10) were injected with 50 µl A549-Luc2 tumor cells either using the MI-TT (n = 8) or SX-TA (n = 2) methods under carprofen analgesia and isoflurane anesthesia. All mice recovered from anesthesia uneventfully. Tumors were monitored with bioluminescent imaging for 5 wk. Surgical time was decreased in the MI-TT group (less than 5 min) compared to the SX-TA group (15–20 min). In contrast to initial concerns that the MI-TT approach would be less reliable, all 8 MI-TT mice expressed bioluminescence signal in the appropriate location while the 2 SX-TA mice were more variable in their signal. We demonstrate that with proper training, a minimally invasive transthoracic approach for intrapleural injection both improves clinical and research outcomes compared to a surgical transabdominal approach. PS80 WITHDRAWN PS81 Increased Anesthetic Success in Rats after Handling C Yancey*, W Williams Comparative Medicine, University of Oklahoma, Oklahoma City, OK Rats (Rattus norvegicus) are commonly used in research for a variety of models, including behavioral, physiological, hearing, and surgical projects. In the rat model of tinnitus and noise-induced hearing loss, Sprague-Dawley rats are anesthetized by intraperitoneal injection of ketamine and xylazine, using 80mg/ kg and 10mg/kg of body weight, respectively. This anesthetic cocktail is required for specific hearing tests, as they do not influence the readings and results by suppressing certain brain functions. Anesthetic success is essential to obtain accurate results at specific time points. During experimentation with a cohort of male Sprague-Dawley rats ranging from 300 grams to

PS82 Differential Effects of 4 Intramuscular Sedatives on Cardiorespiratory Stability in Juvenile Guinea Pigs RP Sixtus*1,2, C Pacharinsak3, C Gray1,2, M Berry1,2, R Dyson1,2 Paediatrics and Child Health, University of Otago, Wellington, New Zealand; 2Center for Translational Research, University of Otago, Wellington, New Zealand; 3Department of Comparative Medicine, Stanford University, Stanford, CA 1

Noninvasive physiological monitoring can induce stress in laboratory animals. Sedation reduces the level of restraint required, thereby improving the validity of physiological signals measured. However, sedatives may alter physiological equilibrium introducing unintended bias and/or, masking the experimental outcomes of interest. We aimed to investigate the cardiorespiratory effects of 4 short-acting sedatives in juvenile guinea pigs. Twelve healthy, 38±3 d-old Dunkin Hartley guinea pigs (6 male, 6 female) underwent 5 treatments in this blinded, randomised, crossover design study: 1 unmanipulated control (no injection), and 4 sedation treatments. Sedation was achieved by intramuscular injection using preestablished minimum effective doses of either alfaxalone (5 mg/kg), diazepam (5 mg/kg), ketamine (30 mg/kg), or midazolam (2 mg/kg) administered in random order with a minimum washout period of 48 h between agents. Sedative depth, a composite score comprised of 5 assessment criteria, was observed every 5 min from dosing until arousal. Physiological monitoring of cardiorespiratory status including measures of heart rate, blood pressure, respiratory rate, and peripheral microvascular perfusion. Ketamine and alfaxalone were most effective in inducing stable sedation suitable for physiological monitoring, and diazepam less so. Midazolam was unsuitable due to excessive hypersensitivity. All sedatives significantly increased heart rate above nonsedated control rates (P < 0.0001), without altering blood pressure or microvascular perfusion. Alfaxalone and ketamine reduced respiratory rate relative to their control condition (P < 0.0001, P = 0.05, respectively), but within normative ranges. Ketamine and alfaxalone are the most effective sedatives for inducing short duration, stable sedation with minimal cardiorespiratory depression in guinea pigs. However, alfaxalone is

the most appropriate sedative for longitudinal studies requiring multiple physiological timepoints.

350 grams of body weight, it was noted that the rate for successful anesthetic induction was 85%. It was later observed that rats in a separate cohort with routine handling prior to anesthetic events had a successful anesthesia induction 97% of the time. These rats were handled approximately 5 min each once daily for 4 consecutive d. Given this observation of successful anesthetic inductions in these 27 rats, a control group was created with the same parameters, but routine handling was not performed. The control group was administered the same dose of ketamine and xylazine. The rats in each group were assigned either fail or pass, dependent upon if they were at an acceptable plain of anesthesia (normal and rhythmic respiratory rate, no toe pinch response, pink in color) within 10 min of injection. Fischer’s Exact Test was used to compare the handled and non-handled groups, with a P value of <0.05. This result highly suggests that handling rats prior to anesthetic procedures will provide a more successful rate of anesthetic success. Given the use of rats in a range of different research models, and the common usage of ketamine and xylazine for anesthesia, this is widely applicable across the research community. Furthermore, these results have important implications for studies that rely on consistency and reproducibility. Future studies that evaluate rat handling and anesthesia should include a larger cohort of animals, multiple strains, both sexes, and should examine the physiological responses and biomarkers of stress before and after handling to further characterize this phenomenon.

PS83 Postmortem Blood and Vitreous Glucose Measurement in the Mouse A Rex*1, J Albrecht2, W Van Alstine3, E Pierpont4, M Rassette1 Department of Veterans Affairs, Minneapolis, MN; 2Gastroenterology, University of Minnesota, Minneapolis, MN; 3Pathology, Pathway Preclinical Services, Minneapolis, MN; 4University of Minnesota, Minneapolis, MN 1

Measurement of blood glucose levels in mice is critical for investigations involving obesity, diabetic, and hepatic disease models. Variation in murine glucose levels can occur not only with experimental manipulation, but also depending on the body site sampled. The question we sought to address was whether it was possible to reliably ascertain a postmortem glucose measurement in the mouse that would approximate the level at the time of death. If possible, this could allow for additional data to be collected in the event an animal was found deceased and the time of death was able to be approximated. Using a glucometer, we measured glucose levels in blood from the tail and retroorbital venous sinus from mice euthanized from a local breeding colony (16 m and F B6.Cg-Speer6-ps1Tg(Alb-cre)21Mgn/J, age range 13-14mo) at time of death, 1 h-, 2 h-, 4 h-, and 24 h postmortem. We also sampled vitreous at time of death and 2 h and 4 h postmortem. Our results demonstrated a considerable drop in measurable glucose levels occurring within 1 h after time of death, reaching very low and stable levels by 2 h after death, across all 3 sampling sites. Variability in glucose levels between collection sites, noted in other studies, was confirmed here. The average blood glucose reading from the tail at time of death was 173.5mg/dL, but by 2 h postmortem was 30.8 mg/dL. The average blood glucose reading from retroorbital venous sinus at time of death was 115.4 mg/ dL, but by 2 h postmortem was 36.8 mg/dL. The average blood glucose reading from the vitreous at time of death was 201.3 mg/ dL. Readings post-mortem from the vitreous could not reliably be taken; the few measures that were able to be taken showed glucose measurements in line with the other sampling sites post 2 h. Our findings do not support the use of postmortem murine glucose measurement to approximate time-of-death glucose levels. While technically possible, vitreous sampling is not a reliable method of postmortem glucose measurement, possibly due to the relatively large lens-to-vitreous ratio in the mouse globe. In addition, the variability observed between blood collection sites reinforces the importance of using a consistent sampling site for antemortem murine glucose measurements to ensure appropriate comparisons. PS84 Comparison of 2 Methods to Train Guinea Fowl to Perform a Behavioral Task L Brossia-Root*1, H Heffner2, R Heffner2 DLAR, University of Toledo, Toledo, OH; 2Psychology, University of Toledo, Toledo, OH 1

To study the evolution of hearing, we must determine hearing of varied species. We discovered that some birds (chickens) can hear infrasound (low-frequency sounds inaudible to humans), whereas most birds cannot (ducks). To determine why some birds can hear infrasound, additional species must be studied. Guineafowl, terrestrial birds similar to chickens, were chosen for hearing testing. To establish their hearing range, birds are trained to continuously peck a response key when there is no sound, and to stop pecking the key when a sound is presented. Training animals to

perform behavioral tasks is challenging and time consuming. Per the Guide for the Care and Use of Laboratory Animals, providing a highly preferred food or fluid as positive reinforcement is recommended instead of food restriction. The goal of this study was to determine if guineafowl could be trained to peck the response key for a highly preferred food reward while fed a standard diet ad libitum, or if food restriction was required. Four guineafowl were free-fed chow and earned sunflower seeds, their highly preferred reward, for pecking the response key during training. After 30 d, the birds rarely pecked the response key for the sunflower seed reward. Therefore, this method of training was unsuccessful. Next, the guineafowl were trained with food access restricted for 23 h while earning chow as their reward for pecking the response key during their 1-h training sessions. Three out of the 4 birds were consistently pecking the response key hence were successfully trained by the end of the 30-d training period, during which body weights gradually increased. These data are consistent with previous studies of both mammals and birds demonstrating they are reliable task performers when food restriction is used during behavioral training.

Surgical procedures should be replaced by less invasive techniques whenever possible to improve animal welfare. Splenic injection, performed via laparotomy approach, is commonly used to deliver cells to the liver in rodent models of liver failure. We investigated a nonsurgical, percutaneous route of splenic injection (PS) in FRGN mice. To assess the feasibility of this procedure, a 3-point scoring system (PSS, 0-Intraperitoneal, 1-Partial, 2-Full) was devised to determine the accuracy of injection into the spleen and deposition of cells in the liver. Animals were anesthetized using isoflurane, and fur was clipped and removed with a depilatory cream. A 29 gauge needle was inserted through the skin and muscle layers to inject the test article into the spleen. In the pilot phase, green food coloring was used to verify the completeness of splenic injection. Technicians (n = 3) reported their scores immediately after injection based on gross observations such as coloring of limbs and snout due to the green dye. Gross necropsy was performed to confirm the location and extent of dye in the tissues. To further assess PS injection, 24 FRGN mice (m/f, aged ~7-wk-old) were percutaneously injected with either LEW-Tg(Gt(ROSA)26Sor-luc)11Jmsk luciferase-expressing Lewis rat hepatocytes (LELH, 1 million cells/rat) formulated in dye or LELH alone. Mice were scored immediately following injection and imaged at 1 h (n = 24) and 24 h (n = 4) post injection. Images were taken using an in vivo imaging system spectrum instrument to confirm delivery of cells to the liver. IVIS images were scored using the same 3-point system. It was observed that 91% of PS injections successfully delivered LELH to the liver: 61% with a strong concentrated dose (PSS 2) and 30% as a partial dose (PSS 1). It was also seen that 80% of the injector-reported scores were a direct match with the IVIS image score. Dye-guided LELH injections did not result in greater accuracy of injection than LELH alone. The scoring system is an effective immediate gross measure to determine the accuracy of the injection. Percutaneous splenic injection is a successful, minimally invasive method of cell administration to the liver and may be considered as an alternative to surgery in mouse models.

PS86 Development of Long-term Cecal Catheterization for Repeated Infusions in Miniature Swine E Callahan*, M Haney Veterinary Services, Sinclair Research Center, Columbia, MO Implantation of infusion catheters in the small intestines has been described in multiple species. Common sites include the duodenum, jejunum, and ileum, but there is limited literature on catheter placement in the cecum or large intestines of swine. The purpose of this study was to develop a surgical method to allow liquid drug delivery directly to the cecum and bypass the stomach and small intestines, while allowing repeated, sedation-free dosing. Male, Yucatan swine (n = 6) underwent surgical implantation of an intestinal burp valve catheter into the cecum. Animals were sedated with tiletamine/zolazepam, xylazine, and atropine, intubated, and maintained on isoflurane. Ketoprofen, buprenorphine SR, and cefazolin were administered prior to the procedure. Through a left paramedian incision, the burp valve catheter was inserted into the cecum and secured. The catheter was tunneled to a subcutaneous (SC) pocket created on the lateral neck. A port head was attached to the catheter and secured to the underlying muscle. All incisions were closed with absorbable suture. Following surgery, ports were aseptically accessed and flushed with sterile saline at least monthly. Cecal catheters were successfully placed in all animals and allowed for repeated cecal infusions. Duration of infusions was up to 6 h and as often as every 4 d. Complications included port infections (n = 2), resulting in euthanasia at 65 and 125 d post-surgery. Infections were localized to the SC space along the port and catheter. Other complications involved port failure (n = 1) due to catheter separation from the port. Catheters remained functional at least 125 d post-surgery in the surviving 3 pigs. In conclusion, cecal catheter implantation is a viable option for repeated infusion dosing into the cecum. This model presents a refinement to more invasive methods by delivering consistent and targeted dosing without sedation. Though alternative methods are needed if sample collection or capsule dosing are required by study design, cecal catheters provide a sustainable route for long-term fluid administration. Thus, cecal catheters facilitate a reduction in animal numbers and improvement in data quality and reproducibility by enabling repeated dosing without the systemic effects of sedation. PS87 Efficacy of a Heated Anesthesia Breathing Circuit for Prevention of Perianesthetic Hypothermia in Rhesus Macaques (Macaca mulatta) PA Bowling*, M Bencivenga, C Reiter Veterinary Medicine, USAMRIID, Frederick, MD This study evaluated the efficacy of using a heated anesthesia breathing circuit in addition to forced-air warming in the prevention of perianesthetic hypothermia in rhesus macaques when compared with forced-air warming alone. Hypothermia is a common perianesthetic and intraoperative complication that can increase the risk of negative outcomes. Body heat is lost through 4 mechanisms during anesthesia: radiation, conduction, convection, and evaporation. Typical warming methods such as forced-air warming devices, conductive heating pads, and heated surgical tables only address radiative and conductive mechanisms of heat loss. A commercially available heated breathing circuit that delivers gas warmed to 104°F can easily be integrated into an anesthesia machine. We hypothesized that heating the inspired anesthetic gas to address the evaporative mechanism of heat loss would result in increased body temperature during

anesthesia in rhesus macaques. Body temperatures were measured by esophageal and rectal thermometer at 5-m increments in a group of ten 5-7 year-old adult male rhesus macaques during two 2-h anesthetic events: one with a heated anesthesia breathing circuit in addition to forced-air warming, and one with forced-air warming alone. Animals were anesthetized with tiletamine/zolazepam to facilitate intubation and maintained under isoflurane inhalant anesthesia. The addition of a heated breathing circuit had a significant positive effect on perianesthetic body temperature, with a faster return to baseline temperature, earlier nadir of initial drop in body temperature, and higher body temperatures during a 2-h anesthetic procedure. Return to baseline was 40.5 m faster (P < 0.05) measured by esophageal temperature and 29.0 m faster (P < 0.05) measured by rectal temperature. As measured by rectal temperature at 5-m intervals, macaques on the heated breathing circuit had higher body temperatures from 70 to 120 m of anesthesia time (P < 0.05). Use of a heated anesthesia breathing circuit should be considered as a significant refinement to thermal support during macaque anesthesia, especially for procedures lasting longer than 1 h.
