Anthelmintic Resistance
نویسنده
چکیده
Parasitic gastroenteritis, caused by roundworms (nematodes), is well recognised as a major production-limiting disease, particularly in lambs. Effective parasite control has become heavily dependent on anthelmintics. The development of anthelmintic resistance by roundworms poses a potential crisis for sheep producers and measures to avert and delay this are essential. This report summarises the main results from studies at Teagasc, Athenry, examining the anthelmintic resistance status of Irish lowland commercial flocks and recommendations to combat the challenges facing producers in controlling parasites are outlined.

Anthelmintic resistance in sheep farms: update of the situation in the American continent.
The present paper reviews the frequency of anthelmintic resistance in sheep farms in different countries of the American continent and describes some aspects that might influence the trend in sheep farms. The situation of anthelmintic resistance in sheep farms has been explored mainly in south of the continent (Argentina, Brazil and Uruguay) where sheep farming is an important industry. In thos...
متن کاملForeword: towards markers for anthelmintic resistance in helminths of importance in animal and human health.
Anthelmintic resistance is a serious problem in veterinary medicine and appears to be developing in some helminths of importance to human health. Anthelmintic drugs remain the principal means of control of helminth infections in animals and humans and the continued dependence on these pharmaceuticals will continue to impose selection pressure for resistance development. Our ability to detect an...

Anthelmintic resistance of parasites in small ruminants, cattle and horses is increasing worldwide as a consequence of the over usage of the currently available products. In Belgium, Cooperia oncophora is the most common cattle nematode in which resistance, especially against macrocyclic lactones, occurs. Once resistance has been diagnosed, a change to another drug with a different mode of acti...
متن کاملAnthelmintic-resistant nematodes in Irish commercial sheep flocks- the state of play
Anthelmintic resistance has been reported in most sheep producing countries. Prior to the mid 1990s, reports of anthelmintic resistance in Ireland were sparse and focused on benzimidazole, one of the three classes of anthelmintic available during this period. This evidence for efficacy issues on Irish farms combined with awareness that anthelmintic resistance was increasingly being reported in ...

Although the molecular bases of resistance to anthelmintic families have been intensively studied, the contributing factors for the development of anthelmintic resistance are less well known. Clear recommendations must be given to farmers in order to delay the onset of anthelmintic resistance. Until now, the main advice has concerned the reduction of treatment frequency in order to slow down th...
