Genomic Analysis of Cardiac Surgery–Associated Mycobacterium chimaera Infections, United States

摘要

A surgical heater–cooler unit has been implicated as the source for Mycobacterium chimaera infections among cardiac surgery patients in several countries. We isolated M. chimaera from heater–cooler units and patient infections in the United States. Whole-genome sequencing corroborated a risk for these units acting as a reservoir for this pathogen.
