Understanding parasite biology and impact is essential when giving advice on parasite control in farm animals. In the first review devoted to parasites of domestic cattle and sheep alone, this book provides in-depth, focused advice which can be tailored to individual farms. It considers the impact of parasites, both as individual species and as co-infections, as well as epidemiological information, monitoring, and diagnostic procedures. Supported throughout by diagrams and photos to aid diagnosis, it also reviews the basis for control measures such as the responsible use of parasiticides, adaptive animal husbandry and other management practices.

Veterinary Clinical Parasitology, Eighth Edition, prepared under the auspices of the American Association of Veterinary Parasitologists (AAVP), emphasizes the morphologic identification of both internal and external parasites of domestic animals. Focusing on the tests and information most relevant to daily practice, the book describes accurate, cost-effective techniques for diagnosing parasitic infections in animals. Including clear, easy-to-find information on the distribution, life cycle, and importance of each parasite, Veterinary Clinical Parasitology offers more than 450 images to aid with diagnosis. The Eighth Edition includes a new chapter on immunologic and molecular diagnosis, increased coverage of ticks and new sections on identification of microfilariae and larvae in diagnostic samples. The new edition also features expanded information on quantitative egg counts, detection of anthelmintic resistance and identification of ruminant strongylid larvae. Additional improvements include many new images throughout the book, revised taxonomic information, a new layout featuring tabs by section to improve user-friendliness, and a companion website offering the images from the book in PowerPoint at www.wiley.com/go/zajac. Veterinary Clinical Parasitology is a highly practical benchside reference invaluable to clinicians, technicians, and students.

First paragraph of Preface: In the preparation of this work the author has aimed to present clearly, concisely, and in orderly manner such matter pertaining to the subject at hand as seems most essential to the needs of the student and the practitioner. Notwithstanding its elementary character, the present rapid advances in parasitology have necessitated numerous changes and additions to the manuscript during its preparation. New species and unsettling facts and theories as to some which are not new are, in these days of intensive research, frequently being brought to light and reported upon. Some of these findings represent or lead to a distinct advance and, though the observations be in certain cases upon obscure and in themselves unimportant species, they may, by analogy, shed valuable light upon life histories and modes of infection of related forms known to be injurious to domestic animals and man. So frequent are these steps forward that it might almost seem better to leave comparative parsitology at the present time to the fragmental attention it has mainly received, and possibly it is to this view that the lack of a recent American volume upon the subject may be attributed. Be that as it may, this book is not intended to be comprehensive, and it contains but little discussion, historical or otherwise, of investigations in the field of medical zoology, -limitaions which may, in measure, contribute to it a longer period of usefulness in its present form than could be hoped for in an exhaustive treatise. With but few exceptions, the parasites considered are those most likely to be met with and as to which most of the facts pertaining to their biology and pathogenicity have been well established.
