Submit a slant or at least = 2.0 mL of a broth culture. Specify the type of media used.
There will be an additional charge for purification/isolation of cultures containing a contaminant, or more than one mycobacterial species.
Organisms submitted on a plate are not acceptable.
Organisms for AST testing without identification
Identification must be provided for isolates when “AST only” is ordered. If identification is not provided, identification testing will be performed and billed accordingly.
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.
AST for Mycobacterium avium complex and other slowly growing NTM strains using a microdilution methodology
4 weeks upon identification of NTM and/or isolation of a pure culture isolate.
