Atlas dedicated to the most important parasites and parasitoses of sheep. It includes numerous resources (images, graphs, tables, flowcharts) to facilitate the identification of parasites and comprehension of their life cycles. Two chapters address examination methods and antiparasitic drugs, thus turning this book into a reference in its field.
The sheep and goat are important to the economies of many countries worldwide through the production of wool, meat and milk. Often raised in open extensive systems, flocks are highly susceptible to outbreaks of disease, and quick recognition of ill-health is a high priority for husbandrymen and for the veterinarians advising them.
A unique resource for all those interested in the impact of worms on livestock, the anthelmintics used to get rid of them and the emerging problem of anthelmintic resistance. This book provides an over-arching view of past, present and suggested future strategies for control of gastrointestinal nematode parasites in sheep and cattle. The book begins with descriptions of the biology of gastrointestinal nematodes, the harm they cause to the host and their economic impact. The main body of the book deals with the control of worms, focusing on the use of anthelmintic drenches. The relationship between drenching practices and the development of drug resistance is discussed, as well as resistance management. The authors also break new ground by discussing alternative options for worm control, including: nutritional interventions, biological control, breeding for desirable genetics and artificially improving immunity to infection. They also offer useful recommendations for program development.
Identification of protozoan parasites in animal tissues is often difficult and confusing. The purpose of this atlas is to create a single reference containing illustrations of the numerous species of protozoans and their stages as they appear within infected tissues. This atlas provides 257 color photographs of these organisms, as well as 36 color photomicrographs of fungi, prepared by techniques that best identify them. It also includes simplified life-cycle drawings as well as brief descriptions of the parasites, hosts, transmission, and pathogenesis. This second edition includes minor textual changes and profound enhancement of the color photographs. The illustrations in this atlas represent the most common stages under optimal conditions for identification. This atlas is intended as an aid for students, teachers, diagnosticians and researchers by facilitating identification of protozoan parasites of animals.
Early diagnosis of parasitic diseases, especially of the opportunistic infections, is gaining importance daily and pathologists now have the chance to make rapid diagnoses of these disorders by examining tissues and body fluids. Though parasitic infections and infestations occur mainly in subtropical and tropical areas, they are increasingly imported into other areas, where the pathologist must be able to recognize them. This new full-colour atlas, containing over 500 photographs, many diagrams and tables, with extensive references and index, concentrates on histology, differential diagnosis and on the structure of parasitic elements such as eggs, larvae and adult worms, in and outside tissues. The atlas will be invaluable as a bench manual for the practising pathologists to keep by the microscope, as well as for physicians, surgeons, dermatologists and pathologists in training, and all those who are concerned with parasitic infections.
