• Resumen

  • The use of nematophagous fungi (NF) is a biological control alternative for gastrointestinal parasitic nematodes (GIN) in ruminants. The aim to the present work was to isolate and to identify nematophagous fungi with potential predatory activity against Haemonchus contortus larvae (L3) in some regions of Mexico. Two hundred and fi fty-nine samples from the soil, roots and ovine, caprine, bovine and porcine feces were collected from diverse zones of the country. Samples were transferred into agar plates, sprinkling technique was carried out and H. contortus L3 were used to determine in vitro nematophagous fungi predatory effect. Plates were incubated at room temperature and were revised under a stereoscopic microscope at 7, 14 and 28 days. The taxonomic identifi cation revealed the presence of seven species of nematophagous fungi: Arthrobotrys oligospora, A. musiformis, A. kirghizica, A. brochopaga, A. conoides, A. superba and Monacrosporium gephyropagum. This is the fi rst report on the presence of A. kirghizica and M. gephyropagum in Mexico. All species had predatory effect against H. contortus L3 however, A. conoides and M. gephyropagum showed the highest predatory activity with 93% and 83%, respectively
