Test Methodology
TB
complex identification may use high performance liquid chromatography to
identify BCG vaccine strains, or a combination of growth characteristics
and biochemicals to identify M. bovis. Pyrazinamide
susceptibility testing is performed using Mycobacterial Growth Indicator Tube
(MGIT) broth.
Turnaround Time
None
Interferences & Limitations
None
Additional Information
Cultures
of M. bovis are resistant to pyrazinamide (PZA). Members
of the TB complex which are resistant only to PZA are M. bovis or
possibly a mono-resistant M.tb.
