Pulmonary mycobacterium chimaera infection
Citation, DOI, disclosures and article data
Pulmonary mycobacterium chimaera infection is a rare form of non-tuberculous myobacterial infection.
Although rare, it is recognized as an emerging opportunistic threat in patients undergoing coronary arterial bypass surgery and open heart procedures requiring extracorporeal devices 1.
It occurs due to Mycobacterium chimaera, a slow-growing non-tuberculous mycobacterium grouped with Mycobacterium intracellulare and Mycobacterium avium to make up the Mycobacterium avium complex.
Along with pulmonary infections, it can also manifest as various cardiac and extra-cardiac conditions such as:
prosthetic valve endocarditis
sternal wound infection
aortic graft infection
disseminated (non-cardiac) disease
