Levamisole- and tetramisole-resistant gastrointestinal nematodes in sheep

Levamisole- and tetramisole-resistant gastrointestinal nematodes in sheep

Veterinarni Medicina 40(2): 45-48

Two experiments were carried out with sheep naturally infected with gastrointestinal nematodes to evaluate efficacy of anthelmintics using in vivo faecal egg count reduction (FECR) test. In experiment 1 with 28 ewes, the following efficacy of anthelmintics given at recommended dose rates was observed: albendazole 99.4%, ivermectin 99.3% and levamisole 81.8%. In experiment 2 with 18 ewes, tetramisole exhibited 71.3% efficacy. Suspected resistance to imidothiazole anthelmintics was confirmed by in vitro larval development test (LDT)--minimal inhibition concentration (MIC) values were estimated at 2.0 micrograms/ml. Infective larvae L3 cultivated from eggs produced by the population of resistant helminths were identified as Ostertagia and Trichostrongylus spp.
