Toward Practical Biological Control of Parasitic Nematodes in Domestic Animals
AbstractIn a series of laboratory and field experiments where the nematophagous fungus Arthrobotrys oligospora was mixed directly with feces it has been demonstrated that it is possible to use nematophagous fungi for biological control of animal parasitic nematodes. A procedure used for selection of nematophagous fungi that can pass the digestive tract of ruminants, horses, and pigs is described. The selected fungus, Duddingtonia flagrans, has been used in further field experiments, and the results have confirmed that by the addition of D. flagrans to feed supplement it is possible to reduce the parasitic burden significantly. Key words: animal parasitic nematodes, Arthrobotrys oligospora, biological control, Cooperia oncophora, Denmark, Duddingtonia flagrans, nematophagous fungi, Ostertagia ostertagi.
