Microbiology for Pre-Health Students
Exam Preparation Guide
Course Introduction
This course offers an in-depth introduction to the fundamental principles of microbiology with a focus on topics relevant to pre-health students. It covers the biology of microorganisms including bacteria, viruses, fungi, and protozoa their structure, function, genetics, and roles in health and disease. Students will explore microbial pathogenesis, the immune response, mechanisms of infection, antimicrobial control, and epidemiology. Emphasis is placed on understanding how microorganisms interact with the human body, disease prevention, laboratory diagnostics, and implications for public health and clinical practice. The course includes both lecture and hands-on laboratory components to develop essential skills for future healthcare professionals.
