Thryonomys swinderianus (grasscutter): a model for One Health implementation
Prof Bassirou Bonfoh Director Consortium Afrique One
frique One, after the inception workshop that gathered 11 Postdocs in April 2011 (Arusha, Tanzania) is now fully operational with the launch of all activities related to capacity building and research agenda. In the last months, the training component was the major activity. In the next couple of months, the training team will be developing the process of negotiating the introduction of the training module into our collaborative universities’ Master and Doctoral courses as a welcome package or supplementary modules for the students and researchers. This process has already received attention from the Deans and Directors as well as the Vice-chancellors during the last major meeting conveyed respectively by Afrique One and the Wellcome Trust (November 2011 in Dar es Salaam). During Afrique One management Board meeting held in October 2011 (Saly Portudal, Senegal) significative progress in activities has been acknowledged by the Deans and Directors who expressed the need to better inform on Afrique One model and its scientific and institutional capacity building offers. The recognition and the relevance of the Postdoc positions in our research centres and universities are appreciated and this “New species” in the academic environment is becoming a tradition taken by some new initiatives (NMIMR in Accra, EISMV, in Dakar) and we are proud of that. Furthermore the FP7-KBBE project “Training of the One Health Next Scientific generation in the Sahel and Maghreb” will be a supportive curriculum development component for Afrique One. Through the application of interdisciplinary and transdisciplinary principles, researchers within Afrique One have identified methodological linkages, institution networking and the huge potential of data and samples sharing across and beyond the consortium. The first outcome of this exercise is the identification of the grass-cutter (Thryonomis swinderianus) as a model for One health implementation research both on its use for understanding the ecology, wildlife conservation, food security; zoonoses risk analysis and captive animal behaviour. We describe here two main cross-country cases studies with a focus on Mycobacterium ulcerans (Buruli ulcer) and Hantavirus transmission to human during husbandry practices and grass-cutter meat consumption. In term of research administration, our future challenges are to overcome some of the research administration such as improving and strengthening the financial system and the development of Afrique One strategic plan beyond the time of the current African Institution Initiative of the Wellcome Trust. The Directorate of Afrique One wishes Happy New Year 2012 and fruitful scientific research.

note on the consortium logo: We likened our efforts to building this consortium to that of building a house. Understanding of higher-level population and ecosystem processes rests hierarchically on sound understanding of simpler processes. Vertically aligned sets of pillars, each representing different zoonotic diseases, support these different levels of our understanding of ecosystem health - the same disease potentially contributing to understanding at different levels. Different colours represent the contributions of different institutions to this understanding, so some pillars are multi-coloured, and of course some pillars await construction.

News Afrique One training activities Afrique One training sessions are gradually established. in June 2010, forty (40) researchers received personalized support for the analysis of their data and the use of R Software. Additionally, a training on qualitative research methodology was held from 22-27 May 2011 in Arusha, Tanzania. Two other courses in Geographic Information Systems (GIS) were held both at the University of Dar Es Salaam (25 participants) and at Dakar Inter-State School of Science and Veterinary Medicine (20 participants) from 1-5 August 2011. The attendants, who accounted for almost all the Afrique One member institutions, were able to establish links strengthening the interconnection of Afrique
One network, and were equaly able to acquire the basics of geographic data management. Several other courses took place, among which a training on molecular biology from 3-14 October 2011 at the University of Dar es Salaam and two trainings for Principal Investigators and Postdocs on scientific article writing and project management (1619 October 2011) during the 5th management board meeting in Saly Portudal, Senegal. The first one provided participants with skills ranging from structuring ideas to the strategy of publication. The second one provided participants with a standardized methodology for the organization and management of projects.
5th Management Board meeting of the Consortium Afrique One From October 17 to 22, 2011, was held in Saly Portudal, Senegal, the 5th Management Board meeting. The meeting was hosted by the Inter-State School of Science and Veterinary Medicine (EISMV), a school under the direction of Professor Louis Joseph Pangui. This meeting was to evaluate the progress of the whole consortium and provide more informations about activities to Dean and Directors from institutions involved in Afrique one but also to some decision makers such as African Union. The meeting was attended by 50 peoples mostly post doctoral fellows, principal investigators, coordination and Scientific Advisory Board (SAB) of Afrique One and several representatives from the Wellcome Trust, the African Union through Interafrican Bureau for Animal Resources

(IBAR) and a satellite institution (Centre International de Recherches MĂŠdicales de Franceville, Gabon) of the consortium. The Deans, Directors and different representatives listed above appreciated the progress of the consortium and proposed some ideas to achieve the goal of Afrique One with their support. Consortium members and invited partners are committed to improving collaboration in order to enhance individual and institutional capacity in Africa research institutions. The Farcha zootechnical and veterinary Research Laboratory (LRVZ) based in Chad, was choosen to host the next meeting of the Management Board in 2012.
3 African Institutions Initiative Workshop, Dar es Salaam, Tanzania Fom 15 to 18 November 2011, was held the African Institutions Initiative Workshop hosted by the Muhimbili University of Health and Allied Sciences (MUHAS), Tanzania and the Wellcome Trust (one of the worldâ€™s largest private medical research charities). Seven consortia were invited SNOWS, THRiVE, CARTA, SACIDS, SACORE, IIDP, and Afrique One. Afrique One was represented by Bassirou Bonfoh (Director), Sayoki Mfinanga (Deputy Director) and Karim Ouattara (Coordinator). In addition, other participants from the Wellcome trust staff, the Consortium for National Health Research (Kenya) and the African Centre for Technology Studies (ACTS), a leading institution for science and innovation policy in Africa, attended this meeting. The last two institutions
agreed to respectively share their experience and help facilitate linkage, exchange activities and collaboration between consortia. The strengths of this meeting were the presentations of the progress made by each consortium, the exchange between wellcome Trust Staff and all consortia, the meeting with the Vice Chancellors from consortia institutions and the meeting with the board. It pointed out the interest to involve institutions leaders in order to facilitate the integration of different consortia staff and management system within their respective institutions. Lastly, a tour visit of key MUHAS and NIMR sites was conducted.

A One Health approach to understanding the transmission of Buruli ulcer in Ghana and Côte d’Ivorie “Across country study” Buruli ulcer is a re-emerging mycobacterial disease that is characterized by necrosis and extensive destruction of affected tissue and bone involvement (osteomylietis) in extreme cases. Limbs and cooler parts of the body are the areas that are typically affected. The disease is focally distributed over about a third of the world with SubSaharan Africa and Australia being the most endemic regions. Prevalence rates range from 1-150/100,000 infected individuals annually. In some endemic countries particularly Ghana, Côte d’Ivoire and Benin, Buruli ulcer is currently the second most important mycobacterial disease coming second to tuberculosis with leprosy being the third. The causative organism, Mycobacterium ulcerans, is a slow growing environmental mycobacterium. It share about 99% sequence homology with M. marinum, a well characterized fish pathogen. The bacterium is localized extracellularly in infected human tissues unlike other mycobacteria, however, in the environment, the DNA has been associated with a wide range of organisms comprising, plants, insects, amphibians, fishes, mammals and humans. As such all endemic communities have slow moving water bodies as a common risk factor. Since the mode of transmission still remains unknown, the work at CSRS is based on the hypothesis the overlapping environmental habitats of the pathogen, animals and humans directly influences the transmission of M. ulcerans. Hence Afrique One intends to outline
zoonotic risk in transmission of M. ulcerans between the environment, small mammals and humans using socio-anthropological and socio-economic data and also provide an excellent platform to the building of capacity in molecular biological methods in identification of strains, which is now at the fore-front of scientific research. Ultimately the information gathered from this work will aid in the adoption of a One Health policy approach to develop possible interventions and contribute to train 3 Msc, 2 Phd and 2 Associated Postdocs.

5 Detection of Hantavirus in the stools of grasscutters «Thryonomys swinderianus» breeding by RT-PCR. The grasscutter is only present in Africa, specifically in sub-Saharan area. It is the rare animal whose meat is struck with no taboos. Everything is used in this animal. Poaching, destruction of natural habitats of animals, ecosystems and species through hunting lead to their depletion. The breeding of big wild rodents such as grasscutter is an alternative. Thus, along with other West African countries facing chronical deficit in animal protein and also in view of maintaining biodiversity through the protection of ecosystems and species, Côte d’Ivoire encourages the breeding of unconventional animal such as the grasscutter. The benefits expected from grasscutter breeding are now multiple: From food perspective, grasscutter meat is highly appreciated by most customers in Sub-Saharan Africa. The grasscutter is much appreciated for its organoleptic qualities. Its use, provides people with the animal protein while ensuring food security. Economically, wild grasscutter is an income-generating activity mainly through the sale of its meat. Globally, evaluated at 76, 8 billion FCFA in 1996 bushmeat accounted for 1.4% of GDP in Côte d’Ivoire. From a scientific point of view, the great grasscutter (Thryonomis swinderianus) as well as some other species, are already used as new laboratory animal. On the socio-cultural point of view, the grasscutter bones are used in traditional medicine and some ritual sacrifices.

the farmer to improve field’s fertility. However, the use of wild and domesticated grasscutter is risky given the constraints associated with various pathologies observed, of which the best known are those under control while some other pathologies still causing the sudden death of the animal, remain an enigma. These pathologies include Hantavirus. The Hantavirus cause asymptomatic infection in rodents and are responsible for hemorrhagic fever with renal syndrome, pulmonary syndrome and kidney disease epidemic in humans. Transmission is made through contact with droppings of infected rodents through biting or aerosols. In Africa, the spread of Hantavirus is poorly known. However, several investigations have noted the presence of pathologies associated with Hantavirus in west and central areas.
The burnt hairs of the grasscutter provides with a powder used in lotions to heal certain wounds. They can also be used as sponge in dermatology. In addition to these roles mentioned above, it is good to know that the domesticated grasscutter is subject to veterinary care which makes its meat a healthy one. The grasscutter is also used as a pet. From the environment and ecosystem perspective, grasscutter breeding contri- This project conducted by UFR Sciences de la Nature butes to sustainable development through the non- (University of Abobo-Adjamé), Institut Pasteur and Centre Suisse de Recherches Scientifiques en Côte degradation of the environment.
