[Integration with the chromosome--an alternative state of calcium-dependency plasmids in Yersinia]. / Integratsiia s khromosomoi--al'ternativnoe sostoianie plazmid kal'tsiizavisimosti u vozbuditelei iersiniozov.

Using the technique of the genes probes the naturally occuring strains Y. pseudotuberculosis and Y. enterocolitica of epidemiological importance were shown to contain pCad plasmid integrated with the chromosome. The strains having integrated plasmid express all pathogenicity determinants necessary for realization of infectious process.
