title: [Strongylids (Nematoda: Strongylidae) of domestic horses in Ukraine: modern state of Fauna and structure of the parasite community].
abstract: Species composition and structure of the strongylid community was studies on helminthological material collected from 162 domestic horses from 11 regions of Ukraine by the in vivo method. Animals were treated with anthelmintic drug "Univerm" (0.2% aversectin C, Russia). Faecal samples (200 g each) were collected from every horse at 24, 36, 48 and 60 hours after treatment; all nematodes expelled (90.851 specimens) were collected and identified. Thirty-three strongylid species from 12 genera (8 species of subfamily Strongylinae and 25--of Cyathostominae) were found in domestic horses in Ukraine. Cyathostominae dominated in the strongylid community; they were found in 100 % horses and composed 98.21% of community. "Core" of the strongylid community was composed by 7 cyathostome species. Decreasing of proportion of Strongylinae in the community for last 40 years was registered; strongylines were found in 37.6% of horses and composed 1.25% of community. Maximal prevalence was 20.98% (Strongylus vulgaris). Bray-Curtis cluster analysis revealed high similarity of strongylid communities in horses from various regions of Ukraine. Difference in general structure of strongylid communities of horses from different horse-keeping conditions was established. Horses from farms with stable-paddock keeping conditions had bimodal strongylid community structure; while horses from stable-pasture keeping conditions possessed multimodal community structure.
