The Mycobacterium avium complex.

Mycobacterium Avium Complex

These two species are difficult to differentiate and therefore they are also referred to collectively as Mycobacterium avium-intracellulare (MAI) . Although it might more logically be termed the Mycobacterium avium-intracellulare complex such nomenclature has not been adopted. They are both opportunistic pathogens that affect the immunocompromised, particularly HIV-positive individuals. They ca...

Consolidations in Nodular Bronchiectatic Mycobacterium Avium Complex Lung Disease: Mycobacterium Avium Complex or Other Infection?

PURPOSE The objective of this study is to define the clinical implications of consolidations in nodular bronchiectatic type Mycobacterium avium complex (NBMAC) infection. MATERIALS AND METHODS A total of 69 patients (M : F = 17 : 52; mean age, 64 years; age range, 41-85 years) with MAC isolated in the sputum culture and nodular bronchiectasis on the initial and follow-up CT scans were include...

Mechanism of Mycobacterium avium complex pathogenesis.

Mycobacterium avium complex (MAC) group of microorganisms are the most common opportunistic bacterial pathogens causing disseminated disease in HIV infected patients. These microorganisms are ubiquitous in nature, and are acquired by respiratory and oral routes. Pathogenesis of MAC depends on the ability of the organisms to colonize intestinal/respiratory mucosa, penetrate the protective barrie...
