title: [Plasmids of Yersinia pseudotuberculosis].
abstract: Plasmids with the sizes of 5.7; 51; 70-77; and 120-130 kb were found in six strains among the ten strains collection of Yersinia pseudotuberculosis. The restriction endonucleases analysis. Southern-blot hybridization and physical maps construction were performed for the plasmids. The 70-77 kb plasmids were found to be analogous to the Ca2(+)-dependence plasmid pYVO19 from Yersinia pestis EV76. The difference between the plasmids of this type is in the insertions or deletions located on the similar fragments of the restriction maps. The 51 kb plasmid has no common fragments with the Ca2(+)-dependence plasmids and does not code for virulence properties of the strain harbouring it. No homology is shared by the 5.7 kb plasmid and the 10 kb plasmid from Yersinia pestis EV76. Replicon of the 5.7 kb plasmid has been used to construct the pVS11 vector plasmid.
