Characterization of moxidectin resistant Trichostrongylus colubriformis and Haemonchus contortus

<br/><br/> The development of moxidectin resistance (MOX-R)in sheep parasitic gastrointestinal nematodes already carrying multiple resistances to other anthelmintic groups has made control of these strains very difficult. The anthelmintic resistance patterns of MOX-R strains of Trichostrongylus colubriformis and Haemonchus contortus were characterized to provide an insight into the remaining role of anthelmintics in the control of such strains. Homozygous MOX-R individuals of both genera were unaffected by moxidectin. For MOX-R heterozygotes a dose rate of 200 mg/kg abamectin (ABA)given orally removed 25
