Population analysis of rodents helminthofauna in the urbanized ecosystems of Kirov oblast

Results of studying the rodents helminthofauna in the urbanized territories of Kirov oblast are presented. 10 species of rodents belonging to 3 families are revealed: Muridae, Cricetidae and Sciuridae. Regularities of distribution the rodents in the explored territory depending on urban saturation are gained. It is shown that all studied rodents have been infected with different types of helminths. The maximum extensiveness of infection (87,5%) is revealed at a gray rat. By number of species of helminths at rodents at the level of classes nematodes which are presented by 11 types that makes more than a half (55%) of total of the found types of all helminths dominate. Further tsestoda which are presented by 5 types of helminths (25% of total of the registered helminths) follow. The minimum specific variety characterizes trematoda - they make 20% and are presented by 4 types of helminths. In work it is experimentally proved that the earthworms living in soils of the urbanized territories are paratenic owners of toxocars and, carrying out, on the one hand, a sanitary role on weeding from invasive toxocars eggs with another are alternative sources of infection of the person and other susceptible animal (owners).
