mycobacterial infection

Etiology: - infection due to Mycobacterium. - tuberculosis is the classic example. - immunocompromised patients: cell-mediated immunity is protective - chronic lung disease - postoperative complications [1] Epidemiology: - atypical mycobacterial pulmonary infections are now more common than pulmonary tuberculosis [2] Pathology: - Mycobacterium avium causes cavitary lung disease [1] - lung disease, skin & soft tissue infections surgical site infections, adenitis, & intravascular catheter-related infections due to - Mycobacterium abscessus - Mycobacterium chelonae - Mycobacterium fortuitum Laboratory: - identification to species level - antibiotic sensitivity varies among species [1] Management: - see more specific infection - for non-tuberculous mycobacterial infection, determine if the isolate is a pathogen, environmental contaminant, or a colonizer - only pathogenic infection needs treatment
