Analysis of 594 isolates of 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 (n = 230) and (n = 224), detected in 14 and 12 countries, respectively. Isolates carrying have increased rapidly since 2021. The increasing detecti...
Whole genome sequencing data of 874 Escherichia coli isolates carrying bla NDM-5 from 13 European Union/European Economic Area countries between 2012 and June 2022 showed the predominance of sequence types ST167, ST405, ST410, ST361 and ST648, and an increasing frequency of detection. Nearly a third (30.6%) of these isolates were associated with infections and more than half (58.2%) were predicted to be multidr...
Background Carbapenem-resistant Klebsiella pneumoniae (CRKP) strains are of particular concern, especially strains with mobilizable carbapenemase genes such as blaKPC, blaNDM or blaOXA-48, given that carbapenems are usually the last line drugs in the β-lactam class and, resistance to this sub-class is associated with increased mortality and frequently co-occurs with resistance to other antimicrobial classes. Ob...
