We have identified IS100 sequences in a specific subset of Yersinia
pseudotuberculosis isolates that were also sensitive to the Y. pestis-
produced bacteriocin, pesticin. In contrast, Y. pseudotuberculosis strains
which did not contain IS100 sequences were not sensitive to pesticin. We
propose that IS100 serves as a molecular marker that identifies a subset of
Y. pseudotuberculosis isolates that have a particularly close evolutionary
and/or ecological relationship with Y. pestis.
