In vitro efficacy of linezolid against vancomycin resistant Enterococci

Vancomycin resistance among Enterococci has been escalating in recent years in many countries. Linezolid, an oxazolidinone is one of the novel drug that promised effective therapy of infections caused by vancomycin-resistant Enterococci (VRE). However, like with most of the previous antimicrobial agents, the clinical benefit of linezolid is being threatened by the emergence of resistant strains of MRSA and vancomycin resistant enterococci VRE, being reported in many countries. This study was conducted to establish linezolid susceptibility of VRE isolates by determining the in vitro activity of linezolid against vancomycin resistant Enterococci, isolated in our setup using fifty VRE isolates. The data collected from this study conclude that the vancomycin resistant Enterococci are 100% linezolid susceptible and presently there is no significant resistance against this unique oxazolidinone in our setup.
