title: [Outbreaks of pseudotuberculosis and intestinal yersiniosis among Soviet specialists and members of their families in the Mongolian People's Republic].
abstract: In summer and winter of 1986 two outbreaks of alimentary enteric diseases occurred among Soviet specialists and members of their families in Ulan Bator. These diseases were identified as Yersinia infections registered in Mongolia for the first time. In July 114 children in a kindergarten fell ill after being fed with salad prepared from vegetables and spring onions supplied from a nearby state farm. 20 Y. pseudotuberculosis cultures, serovar 1, were isolated, and in 25 persons antibodies to the isolated microorganisms were detected; altogether 32% of cases were confirmed by laboratory methods. During the December outbreak 187 persons were affected, among them 90% of children, through the consumption of imported oranges and tangerines, simultaneous infection with Y. enterocolitica, serovars 05.27 and 09, and hepatitis A virus being observed. The fact of associated infection was registered after the simultaneous detection of the markers of viral hepatitis A and Yersinia infection in 61 patients. In the kindergarten the disease produced a typical clinical picture of Far Eastern scarlatiniform fever, and in winter the abdominal forms of the disease prevailed. In cases of combined Yersinia and viral infection a specific variant of acute hepatitis developed; as regards this variant, the authors present heretofore unknown information on its epidemiology, clinical features and outcome.
