Genomics to understand the global landscape of linezolid resistance in <i>Enterococcus faecium</i> and <i>Enterococcus faecalis</i>.

ABSTRACT: Linezolid is an oxazolidinone antibiotic and is a last-line agent for treating infections caused by vancomycin-resistant Enterococcus (VRE). Limited work has been done to study the genomic epidemiology and population structure of linezolid-resistant Enterococcus (LRE) spp. in Victoria, Australia, and globally. We aimed to elucidate the genomic epidemiology and population structure of LRE in Victoria, Australia. We screened our local collection of Enterococcus faecalis and Enterococcus faecium for LRE from 2015 to 2023 and identified 15/349 (4.3 %) and 26/9,207 (0.28 %) E. faecalis and E. faecium, respectively, which had either or both phenotypic and genotypic resistance to linezolid. We next contextualized the Victorian LRE isolates with a global s
