Veterinary Parasitology, 1994
Anthelmintic resistance is widespread in nematode parasites of sheep, goats and horses. Resistance is also developing in nematode parasites of cattle and has been detected in pig parasites. Benzimidazole, levamisole/morantel and ivermectin resistances occur in nematodes of sheep and goats and closantel resistance has been found in Haemonchus contortus.

Veterinary Parasitology, 1993
In populations of livestock in which anthelmintics have become the only means of control, individual worms in some species of helminths evade the effects of specific anthelmintics. If these resistant individuals are selected (by removing the susceptible individuals in the population) then the resistant worm population on individual farms becomes ...

Since the first reports of resistance to the broad spectrum anthelmintics were made some three decades ago, this phenomenon has changed from being considered merely as a parasitological curiosity to a state of industry crisis in certain livestock sectors. This extreme situation exists with the small ruminant industry of the tropical/sub-tropical region

International Journal for Parasitology, 1987
Abstract Modern equine anthelmintics can be divided into at least seven principal groups based on mode of action, i.e., benzimidazoles, pro-benzimidazoles, imidothiazoles, tetrahydropyrimidines, organophosphates, piperazines, and avermectins. The spectrum of activity of these drugs varies and resistance of cyathostomes to benzimidazole and pro ...

Anthelmintics are a class of drugs used to treat infections caused by helminths, or parasitic worms, which include nematodes (roundworms), trematodes (flukes), and cestodes (tapeworms). These medications work by targeting various biological processes essential for the survival and reproduction of these parasites.

In a recent review of the literature we have found references to nearly three hundred substances which have been used against hookworm and Ascaris. 1 Besides this we have tested some three or four hundred other substances on Ascaris in our laboratory.
