| Popis: | Biological control with the use of nematophagous fungi has been described very successfully by many authors and presents itself as a complementary control method, acting on the free-living forms of helminths. The efficacy of a formulation containing the fungus Pochonia chlamydosporia in controlling Fasciola hepatica eggs in faeces was evaluated in an experimental field assay. Two bovine groups (six animals each) were used: A (control) and B (treated with fungus). At 30 days after deworming, the animals were separated into two similar paddocks with flooded areas and were given pellets containing 25 % mycelial mass (group B) or no fungus (group A) at a dose of 1 g/10 kg body weight, twice a week, during 18 months. Faecal samples were harvested fortnightly in the animals of groups A and B and they were submitted at examination of quantitative sedimentation. The mean count of F. hepatica eggs per grams of faeces was significantly higher in group A (1.19) compared with those from group B (0.82) (P |
