Characterization of an ST38 carbapenem-resistant and highly virulent Escherichia coli carrying conjugatively transferable ColV virulence-resistance and blaNDM-5-positive resistance plasmids.

The emergence of such a highly virulent and resistant strain with conjugative blaNDM-5-positive and ColV plasmids posed a significant threat to public health. Implementation of control measures is needed to prevent such strains from further disseminating in hospital settings and the community.
