Macrocyclic lactone resistance in H. contortus seems to be multigenic including the active efflux of these drugs by P-glycoproteins, members of the ABC transporter family, present in this parasite. The goals of the present work were to determine the activity of H. contortus P-glycoprotein 9.1 (Hco-PGP-9.1) and its interaction with the avermectins, ivermectin, abamectin, and also the milbemycin, moxidectin. Additionally, the localisation of Hco-PGP-9.1 was sought in adult worms %K Macrocyclic lactone resistance %K P-glycoprotein %K Transport studies %K Heterologous expression system %K Protein localisation %K Ivermectin %K Abamectin %K Moxidectin %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4730751/
