Edited by Wayne M. Meyers, Ronald C. Neadie, Aileen M. Marty, and Douglas J. Wear, 530 pp, with illus, Washington, DC, Armed Forces Institute of Pathology, 2000.The Pathology of Infectious Diseases, Volume 1: Helminthiases is the first installment of a new series that replaces the older Pathology of Tropical and Extraordinary Diseases. This is a beautiful and informative reference book describing the helminths causing human and veterinary pathology. Edited by members of the Armed Forces Institute of Pathology, the text is a compendium of current knowledge. There are 37 chapters with 530 pages of information and excellent illustrations of the helminths, ranging from the uncommon acanthocephaliasis to the more readily recognized schistosomiasis and cysticercosis.Each helminth has its own chapter, which is divided into an introduction of the parasite, its synonyms, and a historical perspective of how it was originally described. Other sections in the chapter describe the epidemiology, morphology, clinical and pathologic features, diagnosis, and treatment. Each organism is shown with color photographs of its gross appearance as well as many histologic sections revealing their unique structures using a variety of stains. No expense was spared in the production of this text by limiting the number of photomicrographs for each helminth. All the figures in this text are 2 × 3 inches or larger, and all have superb resolution and color. Leafing through this text is like surveying an art book. Black-and-white illustrations of life cycles, electron micrographs, computed axial tomographic scans, and radiographs complete the clinical presentation. Although different contributors wrote each chapter, the organization of the chapters remains the same, so that readers can easily orient themselves to find the information they seek. Another strength is the comparison of each helminth to other similar organisms. The elaboration of key features to distinguish the organism under discussion from “look-a-likes” is invaluable.A collection of tables that guide the reader through the classification of parasitic helminths, the specific morphologic structures useful in their identification, and the size and tissue location of each class of helminth precedes the body of the text. The organization of this vast amount of information into concise comparative tables will be very useful for pathology residents, microbiologists, and infectious disease fellows learning the complexity of parasitology. At the conclusion of the book there is an extensive 30-page index listing each organism by name, country where it may be found, clinical features, and treatment. The index is organized clearly and will be well used by those who have this book. For many readers this book will be too detailed to read cover to cover; it will be utilized as a definitive resource for learning more about a specific parasite.This text is one that will please the experienced pathologist and parasitologist, as well as being a comprehensive starting point for those entering the field. It is a must for libraries to add to their collection. Many scientists will want it for their personal library to access the incredible pictures for teaching and reference. Those who have volume 1 of this new series will be eagerly awaiting the publication of future works from this knowledgeable group of authors.
