Anthelmintics remain the principal means for the prevention and control of subclinical and clinical ostertagiasis. The selection of an appropriate anthelmintic depends on whether one is controlling or preventing Type I ostertagiasis (caused by the establishment of adult worms derived from recently acquired infective larvae), preventing Type II ...

A series of 3-halo-5-phenyl- and 3-phenyl-5-haloisoxazoles has demonstrated anthelmintic activity at doses ranging from 16 to 500 mg/kg orally against the rat roundworm, Nippostrongylus braziliensis. In the 5-phenyl series a halogen at the 3 position of the isoxazole ring was required for activity.

The anthelminthics registered in the Netherlands include albendazole, mebendazole and praziquantel. Available but not registered are ivermectin and diethylcarbamazine. With these five drugs nearly all indigenous and imported helminth infections in the Netherlands can be treated effectively.

Abstract There is now a wide range of potent broad-spectrum anthelmintics for cattle and small ruminants, including the benzimidazoles, the avermectins, tetrahydropyrimidines and imidothiazoles which are highly efficacious against parasite gastroenteritis and bronchitis.

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 ...
