Epidemiology and genetic diversity of linezolid-resistant Enterococcus clinical isolates in Belgium from 2013 to 2021

Objectives: Linezolid-resistant opportunistic human pathogens Enterococcus faecalis and Enterococcus faecium are emerging health threats as limited therapeutic options remain. The aim of this study was to investigate the epidemiology, resistance mechanisms, and genetic diversity of linezolid-resistant enterococci (LRE) isolated between 2013 and 2021 and received at the Belgian National Reference Centre (NRC) for Enterococci. Methods: Linezolid susceptibility testing was performed upon request on 2458 submitted enterococci strains. Whole-genome sequencing was performed on all LRE strains. Resul... Mehr ...
