The blaIMP-14 carbapenem resistance gene has largely previously been observed in Pseudomonas aeruginosa and Acinetobacter spp. As part of global surveillance and sequencing of carbapenem-resistant E. coli, we identified an ST131 strain harboring blaIMP-14 within a class 1 integron, itself nested within a ~54kb multi-drug resistance region on an epidemic IncA/C2 plasmid. The emergence of blaIMP-14 in this context in the ST131 lineage is of potential clinical concern. Copyright © 2016 Stoesser et al.
