Purpose: In the biological cycle of geohelminthiases, the crucial role belongs to the soil. The most important risk factor for infection is the soil of courtyards, child care facilities, sandpits, playgrounds, parks, waste bins and toilets. Sanitary and parasitological studies of these objects are relevant in determination of the risk of infection of the population with pathogens of geohelminthiasis.The aim of the work is to assess the contamination of soil with pathogens of geohelminthiasis at epidemiologically significant objects on the basis of parasitological studies. Methods & Materials: In the period from 2011 to 2019, was carried a study of 13 896 soil and sand samples from preschool institutions and recreational areas in the Republics of Adygea and Karachay-Cherkessia, Krasnodar Krai, Rostov and Astrakhan regions.Flotation methods were used to identify parasitic pathogens. The rates of extensiveness and contamination intensity with helminth eggs of samples were determinate. Also the species composition of parasitic agents and their viability were analyzed. Results: The extensive rate of contamination of soil with eggs of geohelminthiases in the studied territories was: in the Republic of Adygea 23.3%; in the Astrakhan region 17.0%; in the Rostov region 16.5%; in the Republic of Karachay-Cherkessia 12.9%; and in the Krasnodar Krai 5.3%. The share of positive soil samples in preschool institutions and courtyard playgrounds in the studied territories of southern Russia amounted to 18.9%.The intensity of contamination of the soil with eggs and larvae of helminths in analyzed territories varied from 5 - 20 specimens/kg in the Republic of Adygea until more than 24 specimens /kg in the Republic of Karachay-Cherkessia. In the Rostov region, this indicator ranged 0 - 44 specimens/kg, in the Astrakhan region 2 - 22 specimens / kg. In the Krasnodar Krai - on average, the intensity of soil contamination was 16.3 specimens /kg. The share of viable eggs averaged 25.5%. Conclusion: The results indicate high risks of geohelminths in the population, first of all children, in South of Russia. |
