RESULTS OF SEROEPIDEMIOLOGICAL EXAMINATION OF SOUTHERN RUSSIA POPULATION FOR LARVAL HELMINTHIASIS

In order to study the prevalence of parasitic infections in the south of Russia, the results of a seroepidemiological examination were analyzed for antigens Echinococcus granulosus, Toxocara canis, Ascaris lumbricoides and Trichinella spiralis in conditionally healthy population of the Republic of Adygea (n=800) from 2020 to 2024, and the Karachay-Cherkess Republic (n=822) from 2021 to 2024. During the studied period, 1,622 serum samples were examined by enzyme immunoassay. The official statistical reporting data were also analyzed for the incidence of toxocariasis, ascariasis, echinococcosis and trichinellosis. The result analysis showed an increase in persons seropositive for causative agents of ascariasis, echinococcosis and trichinellosis, and a decrease in the causative agent of toxocariasis in the Republic of Adygea. In the Karachay-Cherkess Republic, there was an increase in persons seropositive not only for ascaris, echinococcus, and trichinella antigens, but also a causative agent of toxocariasis. The result analysis of the seroepidemiological monitoring of the population for larval helminthiasis in some territories of the south of Russia indicates a high level of contact among residents of the Republic of Adygea and the Karachay-Cherkess Republic with certain helminthiasis pathogens. The study results show the need for further seroepidemiological monitoring in the south of Russia.
