Phenotypic and genotypic characterization of linezolid-resistant Enterococcus faecium from the USA and Pakistan.

Objectives: Linezolid is an important therapeutic option for the treatment of infections caused by VRE. Linezolid is a synthetic antimicrobial and resistance to this antimicrobial agent remains relatively rare. As a result, data on the comparative genomics of linezolid resistance determinants in Enterococcus faecium are relatively sparse.
