Public Health England (PHE) issued a guidance report on the management of Mycobacterium chimaera endocarditis following cardiac valve surgery. Non-tuberculous mycobacteria (NTM) are opportunistic pathogens that cause illness primarily in the elderly, in the immunocompromised or in patients with underlying lung disease. Tests on some heater-cooler units in Europe, United States and the UK have revealed growth of Mycobacterium chimaera (which is a type of bacteria that is common in the environment but does not frequently Heater-cooler devices, including the Stockert 3T, are most commonly used to warm and cool patients during cardiothoracic surgeries. Mycobacterium chimaera, a species of the Mycobacterium avium complex, is ubiquitous in the environment and is an opportunistic pathogen capable of causing human infections. The authors performed whole-genome sequencing (WGS) of 5 isolates sampled from HCUs in hospitals in . An epidemiological link with use of a specific model of HCUs, the 3T device (LivaNova, UK; formerly Sorin, Germany), was confirmed by the detec-tion of M. chimaera in these devices across affected cardiothoracic surgery centres [4]. Mycobacterium chimaera ( M. chimaera) is an environmental non-tuberculous mycobacteria belonging to the Mycobacterium avium complex. Antigenic peptides are processed within the cell and presented on the cell surface in association with class II MHC molecules. Although most commonly associated with pulmonary disease, there has been growing awareness of invasive M. chimaera infections following cardiac surgery. GENOME ANNOUNCEMENT. Mycobacterium chimaera is one of a group of common slow-growing environmental organisms that sometimes cause respiratory infections or severe disease in people whose immune systems are in some way compromised.
