This book provides a comprehensive reference and diagnostic aid to the practicing pathologist or infectious disease specialist encountering a parasite in an examined tissue sample. Organized by phylogenetic group, the text facilitates diagnosis by discussing common characteristics and patterns of different parasites, and misleading artifacts that resemble parasites in tissue. This second edition includes molecular biology and immunologic aspects, and a more in-depth discussion of syndromes more prevalent due to increased world travel, immigration and the AIDS epidemic.
