Mycobacterial Culture, Blood
Clinical Information: Mycobacteremia occurs most often in immunocompromised hosts. The
majority of disseminated mycobacterial infections are due to Mycobacterium avium complex but
bacteremia can also be caused by other mycobacterial species including, but not limited to,
Mycobacterium tuberculosis complex, Mycobacterium kansasii, Mycobacterium fortuitum,
Mycobacterium chelonae, Mycobacterium scrofulaceum, Mycobacterium szulgai, and Mycobacterium
xenopi.(1) Mycobacterial blood cultures may be indicated for patients presenting with signs and
symptoms of sepsis, especially fever of unknown origin.
Useful For: Diagnosing mycobacteremia
