Notes
MIC testing on slowly growing nontuberculous mycobacteria (NTM) performed using microtiter dilution methodology.
Refer to Interpretive Data section for list of drugs concentrations and interpretations.
Antimicrobial susceptibility testing (AST) performed on NTM isolates by request only.
Per ATS/IDSA statement: Diagnosis, treatment and prevention of nontuberculous mycobacterial diseases (2007), M. gordonae is frequently encountered in the environment and is almost always considered nonpathogenic; therefore, antimicrobial susceptibility testing (AST) for M. gordonae is performed by specific request only. Contact NJH Mycobacteriology laboratory at 303.398.1339 if AST is desired for M. gordonae.
