BRS Microbiology and Immunology is designed specifically for medical and graduate students for successful preparation for the United States Medical Licensing Examination (USMLE). This newest edition features a full-color design and illustrations throughout. The book is divided into 12 chapters and presents both a "bug" approach followed by an organ systems approach. It remains a succinct description of the most important microbiological and immunological concepts and critical details needed to understand important human infections and the immune system function and malfunction. End-of-chapter review tests feature updated USMLE-style questions with rationales and four USMLE comprehensive examinations (in 50 question blocks like Step 1) help test memorization and mastery of the subject.

A companion website offers the fully searchable text and an online question bank.
