Ixodid ticks (Ixodidae) are vectors of protozoan, bacterial, viral and rickettsial diseases including babesiosis of dogs. In recent decades, a large number of cases of canine babesiosis observed directly in the city. Animals often become ill with babesiosis after the attack of ticks in city parks and squares, and even in the courts. This contributes to the formation of stable habitats of Ixodes ticks in urban areas and a sharp increase in the number of dogs in urban population. The study was conducted at the Department of biology, veterinary genetics, Parasitology and ecology. Used integrated epidemiological approach to the study of this problem. Identification of the distribution of ticks was carried out in all agroclimatic zones of the Ulyanovsk region in 2012-2015 Collecting ticks in their natural habitats and in dogs were performed according to standard techniques. Identification of mites was carried out according to the determinant of P. A. Chirov (Saratov, 2000). The results were subjected to statistical processing on a personal computer under the program “Microsoft Office Excel 2007" The study found that, in the Ulyanovsk region was formed biotopes of ticks of 4 species: Ixodes ricinus, Ixodes persulcatus, Dermacentor reticulatus, Dermacentor marginatus. The primary vectors for babesiosis of dogs are ticks of the genera Dermacentor reticulatus (D. pictus), Dermacentor marginatus, Ixodes ricinus, is the dominant genus Dermacentor. We assume that the joint dwelling ticks of the genera Dermacentor and Ixodes contributes to greater stability of the lesion babesiosis of dogs.
В ходе исследований 2013-2015г на территории Ульяновской области был изучен видовой состав иксодовых клещей, являющихся переносчиками бабезиоза собак и распределение их экологических ниш в биотопах различных агроклиматических зон области, отличающихся экологическими условиями. Объектом исследования послужили домашние, безнадзорные животные, собаки из приютов и пациенты ветклиники. Было установлено, что на территории Ульяновской области доминирующими являются клещи рода Dermacentor, которые в сочетании с клещами рода Ixoides формируют стойкие очаги бабезиозной инвазии. Показано, что наиболее активные очаги инвазии Характерны для Центральной и Заволжской агроклиматических зон, характеризующихся высокими интенсивными и экстенсивными показателями инвазии.
