Nematodes of the Genus Trichuris (Nematoda, Trichuridae), Parasitizing Sheep in Central and South-Eastern Regions of Ukraine

Abstract

Abstract Abundance and distribution of nematodes of the genus Trichuris Schrank, 1788 parasitizing domestic sheep (Ovis aries Linnaeus, 1758) were studied in Poltava, Kyiv and Zaporizhzhia Regions of Ukraine. Three species of Trichuris were found, Trichuris skrjabini Baskakov, 1924, Trichuris ovis Abildgaard, 1795 and Trichuris globulosa Linstow, 1901. Trichuris ovis and T. skrjabini were more common (54.9 and 35.7 %), whereas T. globulosa was relatively rare (9.4 %) in the studied material. New species-specific and sex-related morphological characters and metric indices were reviewed as useful in better identification of T. skrjabini, T. ovis and T. globulosa parasitizing sheep.
