First isolation of bla IMP-7 in a Pseudomonas aeruginosa in Japan


We report here the first isolation in Japan of a carbapenem-resistant Pseudomonas aeruginosa strain that carries the metallo-β-lactamase gene bla IMP-7. This isolate revealed high-level resistance to all of the tested antibiotics except for piperacillin, showing a multidrug-resistant phenotype.
