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.

Pyrantel Parasiticide Therapy in Humans and Domestic Animals presents a single source history and reference on the parasiticide activity and pharmacology of the tetrahydropyrimidines and their salts in humans and domestic animals, also collating evidence that resistance to pyrantel has developed in human and domestic animal nematodes. Other books of this nature have been compiled historically for specific anthelmintic compounds, but none has been written to date for the pyrantel family of drugs. Pyrantel, a nicotinic receptor agonist, has been used in domestic animal and human medicine since the 1970's to control two important nematode groups, the hookworms and the roundworms. Given the zoonotic potential of these parasites, pyrantel has served a dual role in helping to protect the health of both domestic animals and the public for more than 45 years.
