Abstract

Following oral administration to sheep, chlamydospores of a Mexican isolate of Duddingtonia flagrans (FTHO-8) survived passage through the digestive tract and subsequently grew on corn meal agar plates. The fungus was able to catch and destroy free-living nematodes and third-stage larvae of Haemonchus contortus added to these plates. Chlamydospores of Arthrobotrys sp. showed a poor resistance to the digestive processes of sheep, although conidia of A. superba survived following oral inoculation in one of two animals.
