<i>Escherichia coli</i> strains possessing a four amino acid YRIN insertion in PBP3 identified as part of the SIDERO-WT-2014 surveillance study

Abstract

<i>E. coli</i> strains of both ST1284 and ST361 lineages, possessing YRIN-inserted PBP3, are disseminating in several regions. The YRIN insertion in PBP3 occurred with multiple β-lactamases, which indicates frequent cross-resistance to other β-lactams.
