The helminth fauna of intestinal canal of red foxes (Vulpes vulpes) in Kharkiv oblast
Journal Title: Бюлетень "Ветеринарна біотехнологія" - Year 2018, Vol 32, Issue
Abstract
Introduction. Parasite fauna of red foxes (Vulpes vulpes) is numerous and diverse. Researchers from different countries studied parasitic fauna of the intestinal tract of fox, but in the scientific literature insufficiently covered the issues of the features of zonal epizootology, the species composition of pathogens of intestinal invasions in foxes, their associations, depending on the natural and ecological landscape of the oblasts of Ukraine. The goal of the work was to investigate the spread of helminths of intestinal canal of foxes (Vulpes vulpes) in Kharkiv oblast and to determine the species composition of helminths and their associations. Materials and methods. The spread of invasive diseases of digestive canal of foxes in Kharkiv oblast was carried through scatoscopic research and partial helminthology autopsy. Materials for the study were feces of foxes. Samples of feces were collected randomly on the natural path of the habitat places and place of stay of foxes. Results of research and discussion. By the results of coproskopic studies it was found that the most numerous parasites of the intestinal tract of foxes were helminths of the class Nematoda (9 species) belonging to the suborders Ascaridata (families Anisakidae and Ascaridae), Rhabditata (family Strongyloididae), Strongylata (family Ancylostomatidae), Trichurata (family Capillariidae, Trichuridae) and Spirurata (family Thelaziidae). It was established that trematodosis caused by Alaria alata was extremely widespreaded among foxes (the extent of the invasion – 92.4% and intensity of the invasion – 3-35 (8 ± 2,9) eggs in the microscope view field). It was found that cestodoses of the fox’s intestinal tract included three species (Taenia pisiformis, Taenia hydatigena, Dipylidum caninum) and were registered in 2.2-3.7% of cases. It were registered that the mixed infestations among the foxes mainly consist of 2-3 and more species of the parasites: single-component – 13.4%, two-component – 42.1%, three-component – 14.2%, four-component – 15%, five-six-component – 7.2%, and seven-component – 2.3%. Conclusions and prospects for further research. The helminths fauna of the red foxes population in Kharkiv region include 13 species of helminths, 8 of which are dangerous to humans (Alaria alata, Taenia hydatigena, Dipylidium caninum, Toxocara canis, Toxocara mystax, Toxascaris leonina, Uncinaria stenocephala, Ancylostoma caninum). It is necessary to monitor invasions of intestinal canal of red foxes. The establishment of invasive agents distribution ways and the study of intermediate hosts of parasites-biogelminthes open up the prospect of controlling the epizootic situation of foxes’ parasitosis.
