ABSTRACT
BACKGROUND:
Mycobacterium chimaera colonizes water-based heater-cooler units (HCUs), from which it can spread to patients during surgery. Vermamoeba vermiformis is a free-living waterborne amoeba, which was consistently present within HCUs.AIM:
To determine whether these amoebae can be involved in the persistent presence of M. chimaera.METHODS:
An in-vitro disinfection model.FINDINGS:
Increased survival of M. chimaera was observed after chlorine exposure in the presence of V. vermiformis. Confocal microscopy demonstrated the intracellular presence of M. chimaera in V. vermiformis.CONCLUSION:
In this way, V. vermiformis can contribute to the persistent presence of M. chimaera in HCUs. Cleaning and disinfection protocols should take this phenomenon into account.Palavras-chave
