Reflection paper on anthelmintic resistance

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...

Foreword: 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...

Refugia--overlooked as perhaps the most potent factor concerning the development of anthelmintic resistance.

Anthelmintic resistance involving particularly the gastrointestinal nematodes of small ruminants is escalating globally, to the extent that in certain countries, such as South Africa, it has already reached alarming proportions, and is affecting practically all the anthelmintics. In this paper it is argued that the high levels of resistance in nematodes of veterinary importance indicate that th...

Anthelmintic-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 ...
