Microbiology is a key subject in medical education, focusing on the identification, classification, and pathogenicity of microorganisms in human health and disease. In the USMLE Step 1 examination, medical students are tested on their understanding of bacterial, viral, fungal, and parasitic infections, as well as host-pathogen interactions, antimicrobial resistance mechanisms, and vaccination strategies. Topics may include microbial structure and function, mechanisms of microbial pathogenesis, diagnostic laboratory techniques, and principles of antimicrobial therapy. Mastery of microbiology concepts is essential for accurate diagnosis of infectious diseases, appropriate treatment selection, and infection control measures in clinical practice.
