The occurrence of the most important @entity2491 serovars in Russia from 1980 to 1993 is reported. Selected @entity2491 strains isolated in Russia from 1951 to 1993 were characterized by serotype, phage type, resistance pattern, plasmid profile and detection of aerobactin production. The incidence of @entity5746 was different in the various administrative districts and varied between 0-235 cases/100,000 inhabitants. Since the middle of the eighties both the overall increase of @entity5746 and the replacement of @entity2491 by @entity10435 was also demonstrable in Russia. @entity580 due to multiply resistant S. infantis strains and @entity2491 strains which caused severe septicaemic courses in @entity1 were a special epidemic problem. These infections mainly occurred via @entity1697 . In contrast ot Western Europe most of the @entity10435 strains isolated in Russia belonged to phage type 1/1. Eight phage types were determined additionally. The @entity2491 strains isolated in @entity580 belonged to a definite phage type and carried a 95 MDa plasmid. This plasmid was also detected in the nosocomial S. infantis strains, S. haifa strains, and S. panama strains. All these nosocomial strains formed aerobactin.
