The distribution of different genotypes of Yersinia enterocolitica strains recovered from humans and from healthy pigs was investigated using PCR fingerprinting. The thirty six strains of Y. enterocolitica from humans, thirty five strains from pigs and Y. enterocolitica ATCC 9610 strain were included in this study. The tested strains of Y. enterocolitica belonged to O3 and O9 serogroups. The PCR fingerprinting using EAE5 primer (5' CTT AAT CTC AGT AAT GCT GGC CTT GG) made it possible to form five groups among the tested Y. enterocolitica strains. Two groups were very numerously represented by the tested strains. The thirty of Y. enterocolitica O3 strains from humans (thirty one of tested) and eighteen of Y. enterocolitica O3 strains from pigs (twenty of tested) belonged to one group. This group also included Y. enterocolitica ATCC9610 strain and four Y. enterocolitica O9 strains from pigs. All investigated Y. enterocolitica O9 strains from humans and the majority of Y. enterocolitica O9 strains isolated from pigs created a second, numerous group. The third genotype was created by two strains O9 from pigs, and the remaining two strains, isolated from pigs, belonging to O3 and O9 serogroups showed different binding patterns revealed by gel electrophoresis and created two other genotypes. The tested Y. enterocolitica strains which were isolated from humans formed only two groups but Y. enterocolitica strains isolated from pigs were found in five groups but such as the Y. enterocolitica strains from humans, the majority of strains from pigs were in first and second group. The Y. enterocolitica O3 strains regardless of their origin mostly represented the same PCR fingerprinting profile. The tested Y. enterocolitica O9 strains were more genetically diverse and represented four PCR fingerprinting profiles.

The nucleotide sequences of the inv, yadA, and ail adhesin-invasin genes were analyzed in 24 strains of the main and nonmain Yersinia pestis subspecies, which were isolated from natural plague foci in Russia and neighbor countries, and ten Y. pseudotuberculosis strains. All of the five plague agent subspecies (main, caucasica, altaica, ulegeica, and hissarica) had the inv and yadA genes altered by insertion of the IS element and a single nucleotide deletion, respectively, as was earlier observed for the Y. pestis strains KIM and CO92. Consequently, the strains lacked functional activity of the Inv and YadA proteins. The ail gene of the main and ulegeica subspecies had a missense mutation, which replaced Val138 with Phe in the Ail protein. The strains of the caucasica subspecies had an AGT insertion in the ail gene, resulting in Ser148 insertion in the polypeptide chain. The changes in the ail sequence probably exerted no effect on ail expression, since the strains of all subspecies were resistant to blood serum complement.
