Harposporium anguillulae is a common nematophagous fungus which colonizes cattle pats deposited in
Brachiaria decumbens pasture in Brazil. To assess its possible effect on free living stages of trichostrongylid nematodes, the reduction of
Haemonchus contortus infective stages in sheep faecal culture was evaluated
in vitro. Addition of 300,000 conidia per gram of faeces caused a reduction of 99.5% compared to the control group. This result indicates that
H. anguillulae could be a candidate for the development of strategies for the biological control of trichostrongylid nematodes.
