Annotation. Recently, much attention has been paid to the interconnection of human activities, the environment and the health of the population. The change in socio-economic relations, the anthropogenic transformation of nature, leads to a change in the living conditions of not only the population, but also the environmental conditions of the causative agents of infectious and parasitic diseases. The spread of diseases among the population largely depends on the ecological and parasitological state of the environment, as many species of parasites pass through one stage of their biological cycle in the environment , can survive for a long time here, keeping its invasiveness. An important component of epidemiological surveillance of parasitic diseases is sanitary-parasitological control of environmental objects, identification of factors contributing to their occurrence and spread, including through soil and water [8].

Keywords: fish and fish products, soil, water sources, sanitary-parasitological studies, dining greens, fruits and vegetables, parasitoses, larva and helminth eggs, sewage.

Main elements of the «viruses + bats» system with their extraordinary susceptibility as the parasitic systemic hosts are considered in this paper. The bat

virom is described and interpreted in detail. The principal parasitic system characteristics per se, pathophisiology and infection process are taken. The great notice devoted to the factors of emergent danger of the true «bat born» viruses – the lyssaviruses of the bats paralytic rabies, paramyxoviruses Hendra and Nipah, filoviruses Marburg and Ebola, coronaviruses of the Several acute and Middle east respiratory syndromes. Their polypathogenicity, diversification, immune evasion, hyper virulence are considered and interpreted in this context.

Keywords: Chiroptera, bat viruses, susceptibility

The poorly studied features of the way of life and the structure of the population of water voles inhabiting the garden and vegetable plots are clarified, and their specificity has been revealed. The number, sexage and phenogenetic structure (based on the color of the coat), the level of splenomegaly (the indicator of possible infection of animals) and the damage caused to cultivated plants are estimated.

Keywords: Arvicola amphibius, agrocenosis, damage, abundance, population structure.
