Emergence and Polyclonal Dissemination of OXA-244–Producing Escherichia coli, France

Abstract

Since 2016, OXA-244–producing Escherichia coli has been increasingly isolated in France. We sequenced 97 OXA-244–producing E. coli isolates and found a wide diversity of sequence types and a high prevalence of sequence type 38. Long-read sequencing demonstrated the chromosomal location of blaOXA-244 inside the entire or truncated Tn51098.
