Results of antimicrobial susceptibility test for slowly growing mycobacteria (SGM). Minimum inhibitory concentration (MIC) range values were recorded along with the resistance percentage of the various SGM tested. Antimicrobial susceptibility testing of SGM was performed by broth microdilution in accordance with Clinical and Laboratory Standards Institute guidelines (CLSI 2011). Except where indicated, MIC values were interpreted based on breakpoints by CLSI (2011).
