Mycobacterium avium complex (MAC) infection in humans is caused by two main species: M avium and Mycobacterium intracellulare; because these species are difficult to differentiate, they also are collectively referred to as Mycobacterium avium-intracellulare (MAI). MAC is the atypical Mycobacterium most...

The incidence of nontuberculous mycobacterial (NTM) pulmonary disease caused by Mycobacterium avium complex (MAC) in apparently immune-competent people is increasing worldwide. We performed a systematic review of the published literature on five-year all-cause mortality in patients with MAC lung disease...
