Polyclonal Dissemination of OXA-232 Carbapenemase–Producing Klebsiella pneumoniae, France, 2013–2021

During 2013–2021, increased prevalence of oxacillinase 232–producing Enterobacterales was observed in France, mostly driven by its emergence in Klebsiella pneumoniae. Whole-genome sequencing identified that oxacillinase 232–producing K. pneumoniae belonged to 14 sequence types (STs), among which 2 polyclonal high-risk clones, ST-231 and ST-2096, were overrepresented.
