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

Abstract

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.
