[Ecological and epizootic characteristics of various zonal types of natural reservoirs of alveococcosis in the Omsk region].

Natural foci of alveococcis of various zonal types were found in the Omsk region. The final pathogen hosts are red (aspen and birch forests, northern and southern forest-steppe, steppe) and corsac (southern forest-steppe and steppe) foxes and, perhaps, wolves (southern taiga). There are intermediate hosts, that are small mammals of 10 species, among which Clethrionomys voles (northern redbacked, large-toothed redbacked, and bank voles in the southern taiga; northern redbacked voles in the aspen and birch forests and northern forest-steppe), root ones (in the northern and southern forest-steppe, and steppe), narrow-skulled ones and house mice (in the southern forest-steppe and steppe) are of the greatest epizootological significance. The seasonal and biotopical dynamics of the spatial pattern of a natural alveococcis foci was established in the subareas of the south taiga and northern forest-steppe.
