Mycobacterium chimaera, belonging to the Mycobacterium avium complex, is an opportunistic environmental mycobacterium which has been isolated from medical device water samples such as Heater Cooler Units (HCU). Laboratories currently use culture-based diagnostic methods to detect M. chimaera, but these take a long time to obtain results.

- The study assesses the effectiveness of the BD BACTEC™ MGIT™ system for detecting non-tuberculous mycobacteria (NTM) in sanitary water, focusing on samples from heater-cooler units and haemodialysis instruments over a five-year period.
- A total of 1,369 water samples from HCUs and 747 from dialysis machines were tested, with 261 and 20 cultures yielding NTM, respectively, verified through advanced techniques.
- Results show that the MGIT system is not only reliable and reproducible for clinical applications but also effective for environmental testing of NTM, detecting concentrations as low as 4 CFU/mL.
The freshwater environment is suitable for nontuberculous mycobacteria (NTMs) growth. Their high adaptability represents a considerable risk for sanitary water systems, which are a potential vector for NTMs transmission. This study investigated the occurrence of NTMs, such as , in hospital water systems to support the surveillance and control of potentially pathogenic NTMs.
