The Potential Use of Vaccines or Genetically Resistant Animals in the Control of Helminthiasis

In a paper I gave recently on the control of helminthiasis in the tropics, I tried to emphasize that a viable sheep or cattle enterprise depended, among other things, on the control of gastrointestinal nematodes (Urquhart 1987). For example, in Australia there is a highly profitable wool industry based on some 150 million Merinos which earn about 1800 million USD in exports. However, the cost of controlling parasitic worms, in terms of anthelmintics alone and excluding labour, is around 40 million USD. Nevertheless, the control of gastrointestinal worms is essential if farmers’ profit margin is to be sustained. Sheep or cattle husbandry which ignores the control of these diseases is almost inevitably doomed to failure.
