Table 2 MIC values [μg/mL (U/mL for polymyxin B)] of 25 antimicrobials used for susceptibility testing of NTM and other Corynebacterineae

From: Studies of antimicrobial resistance in rare mycobacteria from a nosocomial environment

  1. Resistant profile (red shading); intermediate profile (grey shading); susceptible profile (green shading), according to interpretative criteria [18, 68]. When no interpretive criteria are available only MIC values are reported. The dark line separates the antibiotics recommended by the CLSI to be tested for rapidly growing NTM (above the line) from the other 17 antimicrobials tested (below the line)
  2. ND not determined
  3. aStreptomycin is recommended for SGM susceptibility testing but no interpretative criteria are available. Imipenem is recommended for Corynebacterium susceptibility testing but no interpretative criteria are available. The 5 antibiotics with underlined names were utilized in the Middlebrook 7H10-PANTA supplemented isolation medium
