We report a novel IncHI2 plasmid coharboring blaVIM-1, two copies of blaKPC-3, and mcr-9.1 resistance genes in a human Escherichia coli isolate of the new serogroup O188. The blaVIM-1 gene was included in a class 1 integron, mcr-9.1 in a cassette bracketed by IS903 and ΔIS1R, and blaKPC-3 in two copies within a new composite Tn4401-like transposon. The emergence of carbapenem and colistin resistance genes in a single plasmid is of great concern for upcoming clinical therapies.

Abstract
We report a novel IncHI2 plasmid coharboring blaVIM-1, two copies of blaKPC-3, and mcr-9.1 resistance genes in a human Escherichia coli isolate of the new serogroup O188. The blaVIM-1 gene was included in a class 1 integron, mcr-9.1 in a cassette bracketed by IS903 and ΔIS1R, and blaKPC-3 in two copies within a new composite Tn4401-like transposon. The emergence of carbapenem and colistin resistance genes in a single plasmid is of great concern for upcoming clinical therapies.| File | Dimensione | Formato | |
