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

ABSTRACTPoland's firstEnterobacteriaceaeisolate producing the New Delhi metallo-β-lactamase (NDM) was identified in August 2011.Escherichia colisequence type ST410 NDM-1 was cultured from a critically ill patient who had been transferred directly from the Congo. TheblaNDM-1gene 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 anE. coliST131 isolate of Indian origin.
