title: [The gene identification of bacterial species and serovariants by the polymerase chain reaction with universal oligonucleotides: the reidentification of earlier isolated strains of Yersinia pseudotuberculosis].
abstract: Genetic analysis of 19 standard strains belonging to 6 Yersinia species (Y. pestis, Y. pseudotuberculosis, Y. enterocolitica, Y. kirstensenii, Y. frederiksenii, Y. intermedia) revealed that gene typing by the method of polymerase chain reaction (PCR) with the use of universal primers permitted the identification of species in bacterial cultures by PCR patterns and the determination of Y. pseudotuberculosis serovars within 4 hours. By this method 23 Y. pseudotuberculosis strains (serovar 1), earlier isolated in different regions of the USSR from humans and rodents, were studied. The study showed that out of 14 strains of human origin only two strains could actually be classified with serovar 1, while the remaining strains were reidentified as belonging to serovar 5. Among 9 strains isolated from rodents those of serovar 1 prevailed (8 strains). The authors suppose that strains of serovar 5 cause outbreaks and sporadic cases of pseudotuberculosis, occurring considerably more often than it is commonly believed in the USSR.
