MIC distributions of meropenem alone or in combination with QPX7728 [(4), 4 μg/ml; (8), 8 μg/ml] against carbapenem-resistant A. baumannii with genome sequences available (n = 135). The 135 strains produced OXA-23 (n = 71), OXA-72 (n = 16), OXA-24 (n = 16; 2 strains also with OXA-72), OXA-58 (n = 9), OXA-239 (n = 4), KPC (n = 1), NDM-1 (n = 5), and no known carbapenemases (n = 13).
