title: Presence of a virulence-associated plasmid in Yersinia pseudotuberculosis.
abstract: We have shown that Yersinia pseudotuberculosis can possess plasmids which are similar in size and function to the previously described Vwa plasmids of Y. enterocolitica. These plasmids are associated with the production of V and W antigens (calcium dependency) and pathogenicity of the organism. Further investigation of these plasmids from Y. pseudotuberculosis and Y. enterocolitica with restriction endonucleases revealed significant differences in their fragmentation pattern.
