Non-tuberculous Mycobacteria infection (extra-pulmonary)
Infectious agent: Mycobacterium bacteria, except for Mycobacterium tuberculosis, M. gordonae, or M. leprae. These are free-living organisms that are ubiquitous in the environment, particularly soil and water.
Description of illness: Symptoms of extra-pulmonary mycobacterial infection may include fever, fatigue, weight loss, night sweats, lymphadenopathy, surgical site infections, wound infections, cellulitis, granulomas, sepsis, failure to thrive, and osteomyelitis. Healthcare associated M. chimaera infections from contaminated heater-cooler units used in cardiac surgeries have been described; these are often associated with non-healing sternal wounds in addition to the vague symptoms described above.
