Genome analysis of Yersinia pestis from Junggar Basin / 中华微生物学和免疫学杂志

ABSTRACT

Objective To compare different fragment profiles of Yersinia pestis isolated from Rhombomys opimus plague natural focus in the Junggar Basin for determining their genomovars newly found in China.Methods Chromosomal DNA of Yersinia pestis Was extracted with routine method.DFR analysis was performed as reported previously.Results The different fragment profiles of Yersinia pestis from Rhombomys opimus plague natural focus is absence of DFR01,04,06,07,10,13 and DFR 15-18.It is a novel genomovar of Yersinia pestis in China,which is different from Yersinia pestis from the other plague natural foci.Conclusion The genomovar of Yersinia pestis from Rhombomys opimus plague natural focus in the Junggar Basin is a novel one in China.
