For 9 consecutive months (March-November 2008), faecal samples were collected monthly from 129 horses residing within 40 km of Salzburg, Austria. Samples were analysed quantitatively using a modified McMaster egg counting technique. Whenever a faecal egg count (FEC) result exceeded 250 eggs per gram (EPG), the horse was treated with pyrantel, ivermectin or moxidectin. In 52 of 129 horses (40.3%...

Background Countries in the Southeast Asia region have a high prevalence of soil-transmitted helminth, such as roundworm, whipworm, and hookworms [Ancylostoma duodenale, Necator americanus, Ancylostoma ceylanicum]. Recent molecular-based surveys have revealed that A. ceylanicum, a zoonotic hookworm, is likely the second most prevalent hookworm species infecting humans in that part of the world,...

Suppressive anthelmintic treatment strategies originally designed to control Strongylus vulgaris in horses were extremely successful in reducing morbidity and mortality from parasitic disease. Unfortunately, this strategy has inadvertently resulted in the selection of drug-resistant cyathostomes (Cyathostominea), which are now considered the principal parasitic pathogens of horses. Resistance i...

The in vitro response of adults (males and females) and free-living stages of Necator americanus one of the human hookworms, to a wide variety of 20 broad and narrow spectrum anthelmintics was tested. Almost all the broad spectrum anthelmintics influenced males, females and free-living stages at different levels and showed good activity with EC50 values varying from about 0.0002 and 0.0007 mg/l...

Here we review molecular information related to resistance to the cholinergic anthelmintics in nematodes. The amount of molecular information available varies between the nematode species, with the best understood so far being C. elegans. More information is becoming available for some other parasitic species. The cholinergic anthelmintics act on nematode nicotinic acetylcholine receptors locat...
