Filled with highly instructional visual images, this atlas covers typical and atypical presentations of microorganisms covering the breadth of clinical microbiology and offers insightful comments aiding in their identification and clinical significance. It presents more than 425 colored photomicrographs harvested over the author's 40-year career augmented by an up-to-date text describing each microbial entity included. While not a text book, the photomicrographic accompaniment of microorganisms and their clinical presentation should make the atlas of immense value for clinical microbiologists, medical, nursing, and laboratory students, and infectious diseases practitioners.
