Resistance of Trichostrongylus spp. (Nematoda) to benzimidazole in Algerian cattle herds grazed with sheep
Parasitology Research, 2011Co-Authors: B. Bentounsi, Ahmed Khaznadar, Jacques CabaretAbstract:Drug resistance in cattle strongyles to anthelmintics is rarely described in Europe and in the Mediterranean areas. The faecal egg counts are usually low in cattle, and detection of resistance may be particularly difficult. We used the method of twice-repeated treatments and used various estimations of efficacies in order to detect cattle strongyle resistance to benzimidazoles. Resistance was found in two farms among eight that were studied. Trichostrongylus axei was the resistant species in one farm whereas Trichostrongylus sp. was found in another farm. In both farms, there were sheep flocks with a history of strongyle benzimidazole resistance and practice of alternate or mixed grazing with cattle.

benzimidazole resistance in Trichostrongylus axei in sheep long term monitoring of affected sheep and genotypic evaluation of the parasite
Veterinary Journal, 2010Co-Authors: Chrystele Palcy, Anne Silvestre, Jacques Cortet, Colette Sauve, Jacques CabaretAbstract:Abstract This is the first report of benzimidazole (BZ) resistance in the nematode Trichostrongylus axei in sheep. Trichostrongylus axei infects several species of herbivores including sheep, cattle and horses, and the emergence of anthelmintic resistance could lead to significant problems in its control. Benzimidazole resistance in two sheep flocks in central France was detected by post-treatment worm counts. The sequencing of a central region of the isotype 1 β-tubulin gene from adult T. axei recovered post-mortem revealed only one, non-synonymous single nucleotide polymorphism at position 200 (Phe200Tyr), which had already been reported for other nematodes. Seven years after BZ treatment ceased, T. axei helminths present were still resistant to BZ suggesting these parasites do not revert to susceptibility to this anthelmintic, even when the selection pressure had been removed for many years. The findings also highlight major changes in the make-up of the nematode burden in sheep flocks that accompanies the emergence of BZ resistance.

evaluation of the persistent activity of moxidectin 10 long acting la injectable formulation against dictyocaulus viviparus haemonchus placei Trichostrongylus axei and oesophagostomum radiatum infections in cattle
Veterinary Parasitology, 2010Co-Authors: S Ranjan, R Search, E Szewczyk, D M Amodie, R Pollet, D RuggAbstract:Two controlled studies were conducted to evaluate the persistent efficacy of moxidectin (10%) long-acting (LA) injectable formulation against Dictyocaulus viviparus, Haemonchus placei, Trichostrongylus axei and Oesophagostomum radiatum in cattle. The moxidectin LA injectable formulation was administered as a single subcutaneous injection into the proximal third of the ear at a dose rate of 0.01 ml/kg BW to provide 1.0 mg moxidectin/kg BW. The product had persistent efficacy of >90% against D. viviparus, H. placei and Oe. radiatum for at least 150 days post-treatment and against T. axei for at least 90 days post-treatment.
