This title provides medical students as well as physicians with a comprehensive instrument for self-assessment and review within microbiology. The titles in this series contain 500 questions designed to parallel the format and degree of difficulty of the questions contained in Step 1 of the USMLE examination. Each question is accompanied by an answer, a paragraph-length explanation, and a specific page reference to either a current journal article, a text book or both. A bibliography which lists all sources used follows the last chapter of each title within the series.
