MAC bacteria enter most people's body when inhaled into the lungs or swallowed, but only cause infection in those who are [[immunocompromised]] or who have severe [[lung disease]] such as those with [[cystic fibrosis]] or [[chronic obstructive lung disease]] (COPD).<ref name=":0" /> [[Mycobacterium avium-intracellulare infection|MAC infection]] can cause COPD and [[lymphadenitis]], and can cause disseminated disease, especially in people with [[immunodeficiency]].<ref name=Tropical/>{{rp|245}}

During the last decade ''Mycobacterium chimaera'' (see below) infections following cardiothoracic surgery, especially open-heart surgery, have been increasingly reported worldwide.<ref>{{Cite journal |last=Riccardi |first=Niccolò |last2=Monticelli |first2=Jacopo |last3=Antonello |first3=Roberta Maria |last4=Luzzati |first4=Roberto |last5=Gabrielli |first5=Marco |last6=Ferrarese |first6=Maurizio |last7=Codecasa |first7=Luigi |last8=Di Bella |first8=Stefano |last9=Giacobbe |first9=Daniele Roberto |date=2020-03 |title=Mycobacterium chimaera infections: An update |url=https://linkinghub.elsevier.com/retrieve/pii/S1341321X19303459 |journal=Journal of Infection and Chemotherapy |language=en |volume=26 |issue=3 |pages=199–205 |doi=10.1016/j.jiac.2019.11.004}}</ref> Infections usually involve the respiratory system. ''Mycobacterium chimaera'' is acquired during cardiopulmonary bypass via bioaerosols emitted from contaminated heater-cooler units water systems. Due to nonspecific symptoms and long latency, postoperative ''Mycobacterium chimaera'' infections may not be promptly diagnosed and treated, and may become life-threatening.
