Transmission of novel Klebsiella pneumoniae carbapenemase-producing Escherichia coli sequence type 1193 among residents and caregivers in a community-based, residential care setting-Nevada, 2018.

We describe transmission of Klebsiella pneumoniae carbapenemase-producing Escherichia coli sequence type (ST) 1193 in a group home. E. coli ST1193 is an emerging multidrug-resistant clone not previously shown to carry carbapenemases in the United States. Our investigation illustrates the potential of residential group homes to amplify rare combinations of pathogens and resistance mechanisms.
