Use of anthelmintics in cattle
  1. Mike Taylor

    Mike Taylor qualified from Glasgow University in 1976. He is currently 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.


THE parasites of cattle can be broadly categorised into endoparasites, which include helminths, protozoa and some larval stages of arthropods, and ectoparasites, which include ticks, mites, lice and flies. Anthelmintics are used primarily for the treatment of helminth (nematode, trematode and cestode) infections although some broad-spectrum anthelmintics are also active against endoparasitic and ectoparasitic arthropod species. This article describes the range of activity of the major groups of anthelmintics available for use in cattle, and outlines how these drugs may be used in the strategic control of parasitic bronchitis and, in particular, parasitic gastroenteritis.
