Abstract

Analysis of 594 isolates of Escherichia coli sequence type (ST)131 and its single locus variants carrying carbapenemase genes from 17 European Union/European Economic Area countries revealed acquisition of 18 carbapenemase variants, mainly in ST131 clades A and C. Most frequent were bla OXA-244 (n = 230) and bla OXA-48 (n = 224), detected in 14 and 12 countries, respectively. Isolates carrying bla OXA-244 have increased rapidly since 2021. The increasing detection of carbapenemase genes in the E. coli high-risk lineage ST131 is a public health concern.

Keywords: Carbapenem-resistant Enterobacterales; Escherichia coli; antibiotics; antimicrobial resistance; carbapenemase; cross-border spread; surveillance; whole genome sequencing.
