STUDY ON THE SPREAD OF BIO- AND GEOHELMINTHS IN THE CENTRAL CHERNOZEM REGION USING GIS TECHNOLOGIES

The Scientific and Research Institute of Parasitology of the Kursk State University is conducting research aimed at determining the spread of some representatives of geoand biohelminths, such as Тохосаrа spp., Ascaris spp., Spirometra erinaceieuropaei, and Trichinella spp. in the Central Chernozem Region. During the summer and autumn 2024, 3,219 positive samples were received, of which 983 were water samples, 761 were storm drain samples, 791 were soil samples, and 684 were sediments from the bottom of the reservoirs. The study was carried out in the Kursky, Solntsevsky, Zheleznogorsky and Dmitrievsky Districts of the Kursk Region, as well as the Dmitrovsky District of the Oryol Region. The criterion for choosing such districts was the full range of natural and synanthropic factors involved in life cycles of the said parasites. When mapping the results, domestic systems were used, namely, Axioma Geographical Information System (GIS), Yandex Maps software, and Navitel System from Center for Navigation Technologies JSC. A tablet PC with a pre-installed mapping software was used instrumentally. Interactive maps from these manufacturers allow you to quickly enter data on the conducted studies, attach photos and information, and track a hypothetical formation of a focus online. The obtained cartographic material was used to build predictive models for further distribution of parasitic pathogens in the given area.
