Antigens coded by the Ca2(+)-dependance plasmid were found in the cultural medium, cytoplasm and outer membranes of the three monoplasmid (pCadV) strains of Yersinia pestis with the different basic properties. The presence of 20 mM of Mg2+ at least in the medium is necessary for optimal expression of these proteins. The existence of strain differences in the bacterial cells reaction to temperature, cultivation medium has been demonstrated. No difference in the pCad-dependent proteins was found in Yersinia pestis and the causative agents of pseudotuberculosis, enterocolitis.
