Pаrasitological assessment of the prevalence of the larval stage of Dirofilaria spp. and Echinococcus spp. on the territory of the Rostov region
The article considers the parasitological assessment of the prevalence of the larval stage of helminthiases in the Rostov region. Parasitological monitoring was carried out, including literature abstracting, calculation of the intensity, extensiveness of invasion, intermediate and definitive hosts were studied - a reservoir of Dirofilaria spp. larvae. and Echinococcus spp. Using the DNA method, the species classification of pathogens of helminthiases was determined, both in intermediate and definitive hosts. At the same time, it was noted that mosquitoes of the genus Aedes, Culex, Anopheles were identified as a characteristic reservoir host for larvae of the genus Dirofilaria in the territory of the Rostov region, definitive hosts: felines, dogs, ruminants. In case of detection of the disease echinococcosis, small ruminants and cattle were infested. The largest number of cases of infection with the studied cestode in terms of the extensiveness of invasion and the intensity of invasion was registered in the Aksai district of the Rostov region. A low infection rate, the average number of diagnosed larvae, was found in the Neklinovsky district. According to the incidence of dirofilariasis, the highest prevalence was found in the Azov region. A decrease in the number of extensiveness and intensity of invasion was registered on the territory of the Volgodonsk and Neklinovsky districts. The result of the work done is presented in the form of tables.
