For students or those interested in microbiology, Pommerville (biology, Glendale Community College) compiles 15 real life medical mysteries that involve microbial diseases, from Discover magazine's "Vital Signs," published from 1992 to 2000. Stories, about topics from tetanus to HIV, are by physicians who encountered the cases. In this edition, Pommerville revises the late Alcamo's text by adding a new section discussing the steps taken when diagnosing patients, and a glossary and index, as well as new questions. There is no bibliography. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
