Antagonistic activity of Pochonia chlamydosporia against three helminth eggs and characterization of its serine protease.

To address the economic burden caused by livestock parasitic diseases, particularly gastrointestinal nematodes (GIN) and liver flukes, which are exacerbated by growing anthelmintic resistance, researchers are increasingly focusing on biological control strategies as a promising solution. Among these, the fungus Pochonia chlamydosporia has demonstrated promising helminth control properties. This study explored the potential of P.
