Tripoli metallo-β-lactamase-1 (TMB-1)-producing Acinetobacter spp. with decreased resistance to imipenem in Japan

We recently reported Klebsiella pneumoniae carrying bla IMP-type metallo-β-lactamase gene variants showing a paradoxical resistance phenotype: resistance to virtually all β-lactams except imipenem ([1][1], [2][2]). Here we report the isolation of Acinetobacter spp. showing a similar resistance
