Species Composition and Simptoms of Helminthosis of Horses in the Tyumen Region

One of the problems in horse breeding in the Tyumen Region is significant spread of helminthiasis. The purpose of our research was to study the species composition and symptoms of equine helminth infections on the farms in the Tyumen Region. We performed clinical examinations of the animals and coprological studies of horse feces for intestinal helminth infections. We also check the surface contents with perianal, circumanal and perineum swabbing taken with a stick and clear adhesive tape. Тhe diagnosis was confirmed by common laboratory research methods (Fülleborn’s method, helminthoscopy, G. A. Kotelnikov and V. M. Khrenov flotation method). The results of studies found that the horses had Class Nematoda helminths of the suborder Strongylata (Delafondia vulgaris, Strongylus equinus and Trichonema sp.) recorded most frequently with the prevalence of 67.20±2.07% and the infection intensity of 647.10±5.47 eggs per gram of feces; the Parascaris equorum prevalence, 48.00±1.52% with the infection intensity, 409.7±5.4 eggs/g; the Oxyuris equi prevalence, 20.2±1.16% with the infection intensity, 436.40±3.67 eggs/g; and the Strongyloides westeri prevalence, 9.4±0.53% with the infection intensity, 87.60±2.78 eggs/g. Class Cestoda helminths of the species Anoplocephalata perfoliata were found less frequently with the prevalence of 0.20±0.03% and the infection intensity of 10.30±0.74 eggs/g.
