The potential of nematophagous fungi to control the free-living stages of nematode parasites of sheep: survey for the presence of fungi in fresh faeces of grazing livestock in Australia.

In the course of 12 months, 1742 fresh faecal samples from grazing livestock, principally ruminants, from various States of Australia were examined for the presence of nematophagous fungi. In total, 48 separate isolations were made representing various species from the genus Arthrobotrys and also 16 isolates of the single Duddingtonia species, Duddingtonia flagrans. These isolates will be used in continuing studies to select the most suitable species, on the basis of nematophagous capability and ruminant gut survival capacity, for development of a biological means of controlling nematode parasites of livestock.
