The First NDM Metallo-β-Lactamase-Producing Enterobacteriaceae Isolate in Poland: Evolution of IncFII-Type Plasmids Carrying the blaNDM-1 Gene

Poland's first Enterobacteriaceae isolate producing the New Delhi metallo-beta-lactamase (NDM) was identified in August 2011. Escherichia coli sequence type ST410 NDM-1 was cultured from a critically ill patient who had been transferred directly from the Congo. The bla(NDM-1) gene was carried by conjugative IncFII-type plasmid pMC-NDM (87,619 bp), which showed structural similarity to plasmid pGUE-NDM, which was identified earlier in France in an E. coli ST131 isolate of Indian origin.
