Pharmacology of Anthelmintic Resistance
Parasitology Today, 1999Anthelmintic resistance has grown from a curiosity to an important economic problem in several animal industries and is now set to threaten the control of human parasites. The pharmacology of anthelmintics and anthelmintic resistance has been studied most extensively in the nematode parasites of sheep.

Anthelmintic resistance in New Zealand
New Zealand Veterinary Journal, 2001Anthelmintic resistance was first confirmed in New Zealand in 1979 and since then has become common-place; more than 50% of sheep farms now have detectable levels of resistance to one or more chemical classes of anthelmintic. Farmer drenching practices have changed little over the last 15-20 years and are clearly exerting a significant level of ...

Antimicrobic and Anthelmintic Resistance
Veterinary Clinics of North America: Equine Practice, 2000Antimicrobial and anthelmintic resistance are growing issues for the equine practitioner. The development of antimicrobial or anthelmintic resistance is a source of significant concern because of increased frequency of treatment failures and increased treatment costs.

Anthelmintic resistance in cattle
Veterinary Record, 2007SIR — Since we discovered the first case of macrocyclic lactone resistance in nematodes of cattle in the northern hemisphere on a farm in Somerset in 1998 ([Stafford and Coles 1999][1]), there has been little further work in the uk ([Coles and others 2001][2]).

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 ...

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, 1997
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

Anthelmintics and Drug Resistance
Veterinary Clinics of North America: Equine Practice, 1986Equine anthelmintics and the resistance of nematode parasites to anthelmintics are reviewed. Recommendations are made for effective treatment of these parasites and for procedures that can be performed to minimize the problem in the future.

Anthelmintic resistance in India
Veterinary Parasitology, 1996Five sheep farms located in different geo-climatic regions were surveyed for resistance in gastrointestinal nematodes to albendazole, levamisole and ivermectin. Resistance to albendazole and levamisole was evident on all the farms. Albendazole reduced faecal egg counts by 0-73% and levamisole by 0-61%.
