Molecular characterization of blaNDM-5 carried on an IncFII plasmid in an Escherichia coli isolate from a nontraveler patient in Spain.

ABSTRACT

A carbapenem-resistant Escherichia coli isolate (sequence type 448 [ST448]) was recovered from a urine culture of a female patient with no recent record of traveling. PCR screening identified the presence of bla(NDM-5), bla(TEM-1), bla(OXA-1), bla(CMY-42), and rmtB. bla(NDM-5) was carried in a conjugative IncFII-type plasmid (90 kb) together with bla(TEM-1) and rmtB. The genetic environment of bla(NDM-5) showed a structure similar to those of pMC-NDM and pGUE-NDM, identified in Poland and France in E. coli of African and Indian origin, respectively.
