Encompassing twenty-four clinically important and frequently encountered infectious diseases, the text provides all the necessary background and the most up-to-date treatment of the microbes that cause diseases in humans. Each fully illustrated case study is introduced with a patient history, differential diagnosis, clinical clues, laboratory data, pathogenesis, treatment, and prevention. Presented as unknowns, the cases challenge readers to create a differential diagnosis just as they would in practice, including noninfectious causes that could present similar clinical findings.
