Conteúdo: | The nematicidal activity of Bacillus thuringiensis and the possibility of its use as a biological control agent against plant and animal nematodes is in the process of investigation. Brazilian isolates of B. thuringiensis are being tested in our laboratory against trichostrongylid nematodes of ruminants. A bioassay to check efficiency of microbial products (dried culture sediment or a 48 to 72 h culture broth) using faeces positive for Haemonchus contortus is being conducted to evaluate levels of reduction of the free living stages in treated faeces. Reduction levels observed in the preliminary bioassays conducted on seven strains were not statistically significant when compared with controls. Tests are being continued using other isolates.
