Dissemination of NDM-1-Producing Enterobacteriaceae Mediated by the IncX3-Type Plasmid.

ABSTRACT: The emergence and spread of NDM-1-producing Enterobacteriaceae have resulted in a worldwide public health risk that has affected some provinces of China. China is an exceptionally large country, and there is a crucial need to investigate the epidemic of blaNDM-1-positive Enterobacteriaceae in our province. A total of 186 carbapenem-resistant Enterobacteriaceae isolates (CRE) were collected in a grade-3 hospital in Zhejiang province. Carbapenem-resistant genes, including blaKPC, blaIMP, blaVIM, blaOXA-48 and blaNDM-1 were screened and sequenced. Ninety isolates were identified as harboring the blaKPC-2 genes, and five blaNDM-1-positive isolates were uncovered. XbaI-PFGE revealed that three blaNDM-1-positive K. pneumoniae isolates belonged to two different clones. S1-PFGE and southern blot s
