Prevalence of enterococci and its antibiotic resistance in various clinical samples at tertiary care hospital in Southern Rajasthan, India

Deepika Atray, Anshu Sharma, Meena Atray


Background: Enterococci has been emerging as a major cause of infection and gaining increasing clinical importance due to developing resistance to various antibiotics. Emergence of vancomycin resistant enterococci (VRE) in the recent past has been a concern. Aim of the study was to determine the prevalence of enterococci in tertiary care hospital in Southern Rajasthan, India and observe its antibiotic resistance pattern.

Methods: Enterococci strains were isolated from various clinical samples by culture and biochemical methods and its antibiotic susceptibility testing was seen by Kirby Bauer method as per CLSI guidelines.

Results: Out of 100 samples, 50% were isolated from urine samples followed by pus and blood. Resistance to all the drugs was observed with least towards Vancomycin (11%), followed by doxycycline (14%).

Conclusions: The prevalence of multiple drug resistance enterococci with 11% VRE is observed in present study. The study emphasizes on invitro antibiotic susceptibility testing for clinical samples and also rational drug usage.
