Abstract

The spread of the plasmid-mediated colistin resistance gene, mcr-1, into carbapenem-resistant Enterobacteriaceae (CRE) clinical isolates poses a significant threat to global health. Here we report the identification of three mcr-1-harboring carbapenem-resistant Escherichia coli strains, collected from three patients in two provinces in China. Our results show that mcr-1-harboring CRE strains have started to spread in different hospitals in China. In addition, this report presents the first description of chromosomal integration of mcr-1 into a carbapenem-resistant E. coli strain.
