ABSTRACT
Introduction: Enterococci have emerged as important nosocomial pathogens and appearance of resistance to many of the antimicrobials used for Gram-positive organisms has made the management of infections due to Enterococcus species difficult.
Aim: Aim of the study was to observe the prevalence rate of Enterococcus species and observe its antibiotic resistance pattern in our hospital.
Method: 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.Minimum inhibitory concentration (MIC) determination for detecting Vancomycin resistance was done by Himedia E strip test.
Result: In 200 clinical isolates of Enterococcus, 170 were Enterococcus faecalis and 30 species were Enterococcus faecium. Out of 200 Enterococcus isolates 29 were VRE.
Conclusion: The prevalence of Enterococcus species was 5.70% and vancomycin resistance among Enterococci isolates in this study was 14.5% and. Treating serious infections caused by vancomycin-resistant Enterococci has emerged as one of the leading clinical challenges for physicians because of limited therapeutic options.
Key words: Enterococcus, Vancomycin resistant Enterococcus, MIC.
