Resistance to eprinomectin was suspected in a dairy sheep farm southwestern France. The efficacy of topical and injection formulations against gastrointestinal nematodes (GINs) compared using faecal egg count reduction test. GIN species were identified by real-time PCR, concentrations measured serum High-Performance Liquid Chromatography 2 5 days after treatment. Efficacies 99.6% 86.1% for form...

Resistance structures such as chlamydospores produced by the fungus Duddingtonia flagrans allow reduction of infectious larvae from gastrointestinal nematodes. The objective this research was to study effect carbon and nitrogen sources on production in a solid state fermentation system (SSF). Twelve substances were studied using statistical strategy, evaluating their Chlamydospores Finally, an ...

Background: The most important genera of trichostrongylid nematodes that live in digestive tract of ruminants include Teladorsagia, Haemonchus, Trichostrongylus, Cooperia and Marshallagia. Out of the above-mentioned genera, four infect humans including Teladorsagia, Haemonchus, Trichostrongylus and Marshallagia. These parasites are an important part of ruminant pathogens, and some are extremely...
