Geohelminth eggs’ contamination of soils of major social objects in Vladivostok

Abstract

BACKGROUND: Geohellminthiasis accounts for about 90% of all parasitic diseases of the population. In this regard, WHO recommends regular parasitological monitoring of the soil, for the subsequent assessment of its parasitic contamination and the development of appropriate measures for the prevention and prevention of parasitosis among the population. AIM: The purpose is to conduct research on parasitic soil contamination of socially important objects in the territory of the city of Vladivostok METHODS: Soil samples were collected from socially significant objects of the city of Vladivostok the territories of communal households, parks and preschool institutions (DDU). A total of 671 soil samples were collected, the collection was carried out according to MUC 4.2.796-99, soil samples were examined using the Romanenko method. Next, the indicators of the intensity of seeding (EO, %) and the intensity of seeding (IO, ex./kg) were calculated. RESULTS: In total, 7 morphological forms of geohelminth eggs were found: Toxocara spp., Toxascaris leonina, Uncinaria stenocephala, Ascaris spp., Ancylostoma spp., Dypilidium caninum and Taenia spp. Propagative stages of helminths were found in 401 samples out of 671 studied, the prevalence of seeding (EO) was 59.8%. The greatest extent of seeding (EO) was noted for toxocara, eggs of Toxocara spp. were detected in 300 samples and the EO was 44.7%. Geogelint eggs were found in soil samples at all the studied sites, the territories of parks and communal households were the most seeded and rich in parasitic composition. CONCLUSION: Geohelmin eggs were found by us in all territories of socially significant objects, which allows
