Abstract

A 6-kb cryptic plasmid (pYC; 5919 bp) has been recovered from Yersinia pestis isolates originating from regions of Yunnan province in China. The sequence of pYC was determined, and analysis of the sequence has revealed that two of the plasmid DNA regions (ORFs 10 and 11) are similar to the DinJ1 and DinJ2 gene products encoded by Escherichia coli chromosomal DNA. This plasmid is increasingly harbored by Y. pestis isolates recovered from a domestic rodent cycle in the southern regions of the province. Further studies will determine the origin and function of pYC.
