СЛУЖЕБНЫЕ СОБАКИ КАК ИСТОЧНИК РАСПРОСТРАНЕНИЯ ДИРОФИЛЯРИОЗА

Abstract

Due to the peculiarities of keeping and exploitation of service dogs, their frequent movements to various territories both within the country and to neighboring states, this group of animals is an important factor in expanding the range of dirofilariasis. This paper presents the results of a study of infection of service dogs with dirofilaria (Dirofilaria repens and Dirofilaria immitis) for the period from 2010 to 2022 from different territories of the Russian Federation: Rostov, Novgorod, Astrakhan, Orel, Tula, Belgorod, Bryansk and Kursk regions, Krasnodar and Stavropol territories, the Republics of Bashkortostan, Kalmykia and Adygea. 948 blood samples of dogs were studied, microfilariae were detected in 140 samples, in general, the prevalence of invasion was 14,8 ± 1,1 %. D. repens microfilariae were found in 11,0 ± 1,0 % of dogs, D. immitis – 2,1 ± 0,4 %, simultaneously both types of microfilariae (mixed invasion) – 1,4 ± 0,4 %. Analysis of the data obtained indicates a high prevalence of service dogs with this biohelminthiasis. In recent years, there has been a decrease in the incidence among service dogs in the study areas, which was facilitated by active preventive measures: improved diagnosis of dirofilariasis, the use of effective microfilariacid preparations, and vector control.
