AIM The aim was to assess the effect of multi nutrient block (MNB) supplementation with and without tanniferous leaf meal mixture on feed intake, hematological profile, immune response, and body weight changes of goats that were experimentally infected with Haemonchus contortus. MATERIALS AND METHODS Total 12 adult male goats of similar age and body weight (26.49±0.87) were allocated in 3 gro...

The pattern of in vivo uptake of albendazole (ABZ) and its major metabolite, ABZ-sulphoxide (ABZSO), by Haemonchus contortus and Fasciola hepatica recovered from ABZ-treated sheep, was investigated. Concentration profiles of both compounds were simultaneously measured in target tissues/fluids from the same infected sheep. In addition, the proportion of the (+) and (-) ABZSO enantiomers was dete...

The resistance of gastro-intestinal nematodes of small ruminants (sheep and goat) to benzimidazole anthelmintic drugs seems to be linked primarily to a single mutation in the isotype 1 b-tubulin gene. This study was carried out to investigate the origin and diversity of benzimidazole-resistance alleles in trichostrongylid nematodes. We sequenced a 550 bp fragment of the isotype 1 b-tubulin gene...

over one-year period, 150 pasture soil samples and 138 sheep faecal samples, collected from different parts of iran were screened for the presence of nematophagous fungi. the samples were cultured at 25ºc on chloramphenicol-2% water agar (chf-wa) plates in the presence of haemonchus contortus third stage larvae (l3) and checked over a two-month period for characteristic conidia, conidiophores a...
