[Characteristics of the spatial and biocenotic structure of the Transural steppe plague reservoir].

In the trans-Uralian steppe focus, the manifestations of plague are characterized by a cyclical pattern. Nine epizooties, each lasting 1 to 16 years, were identified in this region in 1913 to 1992. The interepizootic periods varied from 1-3 to 17 years.
