Contamination of various types of reservoirs with helminth eggs in the vertical zones of the Kabardino-Balkarian Republic

The article presents research results on determining the degree of contamination of water samples from different water bodies with taeniid-type eggs, considering zonality and specific ecological conditions for infestation with invasive eggs and helminth larvae. The proximity of rivers, lakes, ponds, ditches, canals, puddles, swamps, and mineral springs to populated areas, as well as their closeness to livestock farming regions and the presence of stray dogs, contributes to the deterioration of the sanitary condition of these territories, where the sanitaryhelminthological factor is a primary concern. A crucial task is conducting water monitoring studies for helminth egg contamination, which will help prevent the entry of invasive eggs and larvae into various aquatic ecosystems. Many scientific sources emphasize the need to develop monitoring methods to assess the sanitary and epidemiological state of various environmental objects related to their contamination. The contamination of various water bodies in the vertical zonation zones of the Republic was assessed using sanitary-parasitological research methods. Water samples were investigated using generally accepted techniques. Monitoring data analysis was carried out using biometric methods, and statistical processing of materials was performed using the "Biometry" computer program. In plain, foothill, and mountain zones, these water bodies, excluding mineral springs, exhibit moderate to high contamination with helminth eggs and larvae during spring, summer, and autumn. Contamination levels were higher in poorly maintained riverbanks adjacent to private homes, gardens, farms, orchards, and other agricultural facilities, posing a sanitary and hygienic threat and risk to animals and the population.
