Anthelmintic resistance is reported in equine nematodes with increasing frequency in recent
years, and no new anthelmintic classes have been introduced during the past 40 years. This …

Over the past 10–15 years, we have witnessed a rapid increase in both the prevalence and
magnitude of anthelmintic resistance, and this increase appears to be a worldwide …

Antiparasitics acting on endo-or ectoparasites represent the second largest segment of the
global animal health market, accounting for 23% of market share. However, relatively few …

The avermectins and milbemycins contain a common macrocyclic lactone (ML) ring, but are
fermentation products of different organisms. The principal structural difference is that …

Anthelmintics have been applied indiscriminately to control horse nematodes for over 40
years. Three broad-spectrum anthelmintic classes are currently registered for nematode …

Parascaris equorum and cyathostomins are currently considered the most important
parasites of horses and have traditionally been controlled with anthelmintics belonging to …

Anthelmintic resistance in equine cyathostomins is both widespread and highly prevalent in
the benzimidazole and tetrahydropyrimidine classes; however, reports of resistance to …

During the past two decades anthelmintic resistance in equine parasites has been found in
the group of small strongyle species (cyathostomins) and in the ascarid species Parascaris …

The increase of anthelmintic resistance in the last years in the nematode population of
veterinary importance has become a major concern. The objective of the present study was …

Cyathostominae are ubiquitous to grazing horses and regarded the most prevalent internal
