Emergence of Proteus mirabilis carrying the blaVIM-1 metallo-β-lactamase gene

ABSTRACTSeven genetically related Proteus mirabilis clinical isolates from a hospital in Thessaloniki, Greece, exhibited decreased susceptibility to imipenem and carried a blaVIM-1 metallo-β-lactamase gene. PCR mapping revealed that blaVIM-1 was part of a class 1 integron that was probably located in the chromosome and also included the aacA7, dhfr and aadA genes. This is the first description of the blaVIM-1 metallo-β-lactamase gene in P. mirabilis.
