Parasites of goats: a guide to diagnosis and control
  1. Mike Taylor

    Mike Taylor is head of parasitology and ecotoxicology at the Veterinary Laboratories Agency, Weybridge, honorary lecturer in parasitology at the Royal Veterinary College, and visiting professor in veterinary parasitology at the University of Wales. His special interests include epidemiology and control of helminth and protozoal endoparasites, and ectoparasites, drug resistance, parasite pathology and parasite zoonoses.


GOATS share a number of diseases in common with sheep and cattle and this is particularly true with regard to parasitic infections. The most important endoparasitic diseases seen in goats are parasitic gastroenteritis caused by gastrointestinal nematodes, and coccidiosis caused by protozoan parasites of the genus Eimeria. Other internal parasitic infections seen in goats include cryptosporidiosis, a rapidly emerging zoonotic infection of domestic animals (and humans), adult tapeworms and several metacestodes, and insect larvae of the family Oestridae (bots and warbles). Ectoparasites may be found either permanently on goats (eg, mites and lice) or only when they come to feed (eg, ticks and flies). Such parasites may be a source of annoyance or may result in illthrift and disease. This article discusses the pathogenesis, diagnosis and control of the major endo- and ectoparasitic infections of goats.
