Mycobacterium avium complex infection history and symptoms

Several different syndromes are caused by Mycobacterium avium complex (MAC). Disseminated infections are usually associated with HIV infection. Less commonly, pulmonary disease in nonimmunocompromised persons is a result of infection with MAC. In children, the most common syndrome is cervical lymphadenitis.

In HIV infected persons, manifestations include night sweats, weight loss, abdominal pain, fatigue, diarrhea, and anemia.
