MIC values for NDM variants under standard conditions

^a Antibiotic abbreviations used are as follows: Amp, ampicillin; Ceph, cephalothin; Cefotax, cefotaxime; Ceftaz, ceftazidime.

^b Variants are all expressed in the same strain, E. coli DH10B.

^c Control is an expression vector with no bla_NDM insert (pHSG298).

^d Reductions in MIC values (relative to NDM-1) ≥ 2-dilutions are marked in green. Control is not included in the color coding.
