This work is a practice-oriented diagnostics manual designed for the detection and control of parasitic infections of domestic animals (cattle, sheep, goat, horse, mule, camel, swine, and poultry). Describing the vast range of parasites occurring in temperate climates, in Africa, in tropical as well as subtropical regions, the manual's edge over previous publications lies in its wealth of illustrations. In 200 colour photos, more than 300 black-and-white photos, and many drawings, the author shows the pathogenes and the clinical symptoms caused by them, thus facilitating diagnosis in an unprecedented fashion. Furthermore, the profile of each and every affliction there includes a list of adequate means of therapy and prophylaxis. In this context the manual names the active substances of numerous products manufactured or distributed by leading pharmaceutical companies (Hoechst, Bayer, Merck Sharp & Dome, Pfizer, Janssen, Rhone, Merieux, SmithKline, Beecham, Virbac, etc.)
