Genomic Characterization of Two Escherichia fergusonii Isolates Harboring mcr-1 Gene From Farm Environment.

ABSTRACT: The prevalence and transmission of mobile colistin resistance (mcr) genes have led to a severe threat to humans and animals. Escherichia fergusonii is an emerging pathogen which is closely related to a variety of diseases. However, the report of mcr genes harboring E. fergusonii is still rare. One study in Brazil reported the E. fergusonii isolates with IncHI2-type plasmids harboring mcr-1. A Chinese study reported two strains carrying mcr-1 gene with the same plasmid type IncI2. Here, we identified two strains of E. fergusonii carrying mcr-1 gene from farm environments with IncX4-type and IncI2-type plasmids, respectively. To our best knowledge, this is the first report about mcr-1 gene located on IncX4-type plasmid in
