First Indian report of IncX3 plasmid carrying bla(NDM-7) in Escherichia coli from bloodstream infection: potential for rapid dissemination

Enterobacteriaceae with bla(NDM-7) is only infrequently observed. Self-transmissible plasmids carrying the bla(NDM) gene increase the dissemination of carbapenem resistance in developing countries. This study investigates the whole genome sequence of a bla(NDM-7)-positive Escherichia coli. The isola...

Sumario:Enterobacteriaceae with bla(NDM-7) is only infrequently observed. Self-transmissible plasmids carrying the bla(NDM) gene increase the dissemination of carbapenem resistance in developing countries. This study investigates the whole genome sequence of a bla(NDM-7)-positive Escherichia coli. The isolate was an extended-spectrum β-lactamase producer by combined disc diffusion test and carbapenemase producer by CarbaNP method. Sequencing results revealed the isolate as E. coli ST-167 with IncX3 plasmid carrying bla(NDM-7) in addition to bla(TEM-1) and bla(CMY-42) genes. The identification of IncX3-bla(NDM-7) combination is the first report in India where bla(NDM-7) is known to cause higher resistance to carbapenems compared to its variants.
