many parasitic helminthes of veterinary importance have genetic features that favor development of anthelmintic resistance, this becoming a major worldwide constrain in livestock production. the de-velopment of anthelmintic resistance poses a large threat to future production and welfare of grazing animals. development of variable degrees of resistance among different species of gastrointestina...
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...
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...
Sheep and goat nematode resistance to anthelmintics: pro and cons among breeding management factors.
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...
Pleurotus eryngii is a mushroom growing in the Bakhtiari province of Iran and is known as a mountain fungus. The fresh fungus is used as a food, and when dried its powder has been used as an anthelmintic drug. We decided to study the anthelmintic activity of P. eryngii on Hymenolepis nana (cestode) and Syphacia obvelata (nematode), using experimental animals. Water extract of P. eryngii wa...

Dung beetles (Coleoptera: Scarabaeoidea) support numerous ecosystem functions in livestock-grazed pastures. Exposure to veterinary anthelmintic residues in livestock dung can have lethal and sublethal effects on dung beetles, and can reduce rates of dung removal, but the immediate and longer-term consequences for other dung beetle mediated functions have rarely been studied. We investigated the...
PURPOSE OF REVIEW With the London Declaration on neglected tropical disease (NTD), we are entering a new era of combating NTDs. However, the worldwide prospects of increased mass drug administration (MDA) treatments warrant caution on the development of anthelmintic resistance. In this review, we discuss the practical implications of MDA programs on the development of anthelmintic resistance in...
The development of anthelmintic resistance and high cost of conventional anthelmintic drugs led to the evaluation of medicinal plants as an alternative source of anthelmintics. Traditional medicines act as a source of easily available effective anthelmintic agent. In the current study, In vitro experiments were conducted on Indian adult earthworms (Pheretima posthuma) to determine the possible ...
The Anthelmintic activities of methanolic and aqueous extracts of stems of Achyranthes aspera linn. were evaluated separately on Indian adult earthworms Pheretima posthuma (Annelida). For this work the stems were extracted separately with methanol and distilled water by following maceration method. Various concentrations (2.5, 5, 10, 20 mg/ml) of each extract were tested for anthelmintic activi...
