Abstract

Abstract. One of the most obvious and long-lasting consequences of the Chernobyl nuclear power plant accident is the creation of an exclusion zone and a zone of unconditional (compulsory) alienation. The effect of succession is manifested in the fact that a significant part of aquatic and terrestrial ecosystems as of 1986 were artificial or semi-artificial systems that were under regulatory control by humans. In order to study the parasitic systems of the exclusion zone as informative indicators, mice were selected. Among the mice studied for the presence of agents of parasitic diseases were field (Apodemus agrarius) and yellow-necked (Apodemus flavicollis). A study of them was conducted for the presence of agents of blood-borne parasitic diseases.

Examination of mice blood smears revealed the presence of agents of blood parasitic and infection diseases in all of the investigated animals. Among the agents of these diseases were identified: Trypanosoma spp., Babesia spp., Rickettsia spp. and others. Trypanosoma spp. was identified for the first time on the territory of Ukraine in blood smears of 3 mice among investigated, which were 25 % (95 % confidence intervals 6.8–54.1). The number of parasites in 200 fields of view of the microscope from the studied mice varied from 2 and 6 till 25.

Key words: haemoparasitic diseases, mice, Apodemus flavicollis,  Apodemus agrarius, Trypanosoma spp.
