[The epidemiology of Yersinia infections in the central taiga subzone of the eastern European plain]. / Epidemiologiia iersiniozov v podzone srednei taigi Vostochno-Evropeiskoi ravniny.

The seroepidemiological survey of the population in four southern regions of the Komi Republic for the presence of pseudotuberculosis and enteric yersiniosis was carried out. The survey revealed a high level of seroconversions to with respect to enteric yersiniosis (26.2 +/- 2.7% with the average antibody titer being 2.6 +/- 0.2 log2) and rare contacts of the rural population with Y. pseudotuberculosis (0.4%). Moreover, the intensity of contacts of the population with the infective agent was found to be closely related to the type of cattle breeding farms: the highest level of the immune stratum (32.2%) was registered among those persons whose residence was situated near large cattle breeding complexes. The prevalence of Y. enterocolitica, serovar 0:5, has been noted: to this serovar 87% of all positive reactions were obtained. The study of medical histories revealed that is some cases the disease manifested itself in the form of acute gastroenteritis.

[The prevalence of cryptosporidiosis among the city population of Russia and Belarus]. / Rasprostranenie kriptosporidioza sredi naseleniia nekotorykh gorodov Rossii i Belarusi.

A total of 248 adults (170 with somatic diseases and 78 with the diarrheal syndrome) and 1206 children (323 attending kindergartens, 231 with somatic diseases, and 652 with the diarrheal syndrome), residents of seven towns of Russia and Belarus, were examined for cryptosporidiosis in 1989-1992. The mean infection rate of children and adults with the diarrheal syndrome was 4.8 and 2.7%, respectively, of those with somatic diseases 2.6 and 0% respectively, and of healthy children 1.9%. Children living in the towns of Belarus, localized in the radiation contamination zone, were more frequently infected than children living in other towns. The towns of the European Russia and Belarus should be regarded as stable foci of cryptosporidiosis infection.
