anthelmintic resistance
frequent dosing of animals, especially ruminants running at pasture, selectively retains worms with innate resistance to a particular anthelmintic. A population of resistant worms may result. The resistant worm population may be transmitted to other farms. Side resistance to other compounds in the same chemical group may occur. This is observed in the benzimidazole group of compounds and in the levamisole-morantel group.
