Abstract: The results of the molar investigation in 200 Rattus flavipectus individuals showed that in the population of Rattus flavipectus, 68.5% were more than one year old (62% were 1-3 year old), 31.5% were less than to month old. In 344 infected individuals, which confirmed by bacterial isolation, 85.76% were more tha onen year old and 14.24% were less than one year old. Tbis character of age distribution reflected the patterns of ecological succession and plague epizootics in the Rattus flavipectus population.
