Calcium independent mutants of two Yersinia pestis strains were studied. Insertions of IS100 element at three different sites of plasmid pCad within calcium dependence region were detected in Y. pestis EV, as well as two extensive deletions covering the whole region. It was shown that IS100 carries no HindIII sites. Novel IS element of Y. pestis designated IS101 was discovered in strain 358, in addition to IS100. It is distinguished by a slightly smaller size, HindIII site presence and high specificity of integration.
