[Yersinia pseudotuberculosis in a model marine ecosystem (experimental research)].

Abstract
Materials on the behavior of Y. pseudotuberculosis in the model of marine ecosystem are presented. Y. pseudotuberculosis, both carrying and having lost the virulence plasmid of 45 MD, die in nonsterile sea water, but are capable of prolonged survival in sterile sea water and in the bodies of echinoderms. The death of these bacteria is accelerated in the presence of larvae of echinoderms. In sea water at low temperature Y. pseudotuberculosis maintained their high pathogenicity potential which they use on contact with eukaryotes. Under these conditions Y. pseudotuberculosis preserve their virulence plasmid, thus causing the disease and death of animals.
