Sequence type 11 Klebsiella pneumoniae, coproducing NDM-1 and VIM-1 metallo-β-lactamases, were isolated in a Greek hospital. blaNDM-1 was part of a Tn125 derivative, located on an ~90-kb plasmid similar to the NDM-1-encoding plasmid pB-3002cz. blaVIM-1 was located in an In-e541-like integron, carried on a multireplicon (IncA/C and IncR) plasmid of ~180kb.

OBJECTIVES: An Enterococcus faecium isolate (Efa-125) carrying both the vanA and vanB genes was recovered from a patient with bacteraemia treated in a Greek hospital. Since this is the first description in Europe of E. faecium carrying both vanA and vanB genes, the isolate was further studied. METHODS: Susceptibility to several antibiotics was determined using the VITEK®2 automated system. The isolate was typed by multilocus sequence typing (MLST). To define the genetic units of the vanA and vanB genes, the plasmid content of Efa-125 was analysed by pulsed-field gel electrophoresis (PFGE) of total DNA digested with S1 nuclease followed by hybridisation with digoxigenin-labelled vanA and vanB probes. In addition, plasmids and chromosomes were sequenced using the Illumina MiSeq platform. RESULTS: E. faecium Efa-125 belonged to ST117 and expressed resistance both to vancomycin and teicoplanin, with minimum inhibitory concentrations (MICs) for both of 256mg/L. The vanA gene was carried on a 29 320-bp plasmid exhibiting high similarity to pA6981 previously characterised from Enterococcus gallinarum A6981, whereas vanB was part of a Tn1549-like transposon integrated into the chromosome. Expression of the VanA phenotype was correlated with the presence of intact vanZ and vanS genes. CONCLUSIONS: This is the first detection in Greece of vanA-vanB genotype/VanA phenotype E. faecium and indicates an evolving epidemiology of vancomycin-resistant enterococci.
