[Ecological and epizootic characteristics of various zonal types of natural reservoirs of alveococcosis in the Omsk region]. / Ekologo-épizootologicheskaia kharakteristika razlichnykh zonal'nykh tipov prirodnykh ochagov al'veokokkoza v Omskoi oblasti.

ABSTRACT

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.
