IPM = imipenem; MER = meropenem; CTX = cefotaxime; CAZ = ceftazidime; FEP = cefepime; SXT = sulfamethoxazole-trimethoprim; GEN = gentamicin; AMK = amikacin; TGC = tigecycline. Transformed E. coli strains are indicated as Top10 and the number corresponding to the clinical sample from which the plasmid was obtained.

In transformed Top10 strains, MIC values of imipenem and meropenem were obtained by Vitek (first MIC value) and E-test (second MIC value in italics).
