Helmintofauna of sheep and goats in Dnipropetrovsk region

Abstract

Wormsof classes Nematoda Rudolphi, 1808, Trematoda Rudolphi, 1808 and Cestoda Rudolphi, 1808 were registered in small ruminants (sheep and goats) in Dnipropetrovsk region. Identified nematodes belongto Strongylata Railliet et Henry, 1913, Rhabditata Chitwood, 1933 and Trichurata Skrjabin, 1915. Among the trematodes, representatives of Fasciolata (Skrjabin et Schulz, 1935) were identified. Cestodes were represented by Anoplocephalata (Skrjabin, 1933). Among the specific types of nematodes,representatives of the Strongylata suborder were found: Muellerius sp., Protostrongylus sp., Haemonchus contortus Rundolphi, 1802, Nematodirus sp. Among the helminths Rhabditata we identified Strongyloides papillosus Wedl, 1856, Trichurata –Trichuris sp., Fasciolata –Fasciola hepatica Linnaeus, 1758 andDicrocelium lanceatum Stiles et Hassall, 1896, Anoplocephalata –Moniezia expansa (Rudolphi, 1810) andM. benedeni (Moniez, 1879). The dominant species among worms in ungulates was defined as nematode H. contortus. The smallest share in the group was taken by trematode species F. hepatica and nematodesTrichuris sp. The highest biodiversity indices are recorded in samples of material selected from ungulates consuming pasture herbage from May to September (ten species of worms belonging to three classes:Muellerius sp., Protostrongylus sp., H. contortus, Nematodirus sp., S. papillosus, Trichuris sp., F. hepatica, D. lanceatum, M. expansa, M. benedeni were registered). In animals not pastured throughout the year three types of worms of the class Nematoda: S. papillosus, H. contortus and Nematodirus sp. were defined.
