The Mycobacteriology section identifies Mycobacterium species, with an emphasis on detection of Mycobacterium tuberculosis.  Patient specimens are processed and analyzed by fluorescent microscopy and liquid culture.  Smear positive specimens from respiratory sites that are identified by microscopy are further tested by nucleic acid amplification for rapid detection of M. tuberculosis.  Liquid culture positive specimens, after confirming the presence of acid-fast bacilli by microscopy, are analyzed by high performance liquid chromatography (HPLC), which can identify Mycobacterium species or groups.  Reference culture isolates sent to the laboratory are also confirmed by microscopy and tested by HPLC.  The Mycobacteriology laboratory also performs susceptibility testing on all Mycobacterium tuberculosis isolates, with automatic referral to the CDC for any isolate determined resistant to primary drug therapy (streptomycin, isoniazid, rifampin, ethambutol, and pyrazinamide).

For all human specimens submitted for microbiology testing, see the Microbiology Specimen Submission Guidelines for specific collection, rejection, and transport guidelines.

Packaging and Shipping information for reference cultures

Blood samples require special collection procedures, and should be coordinated with the laboratory to increase chances of mycobacteria recovery.
