Prevalence and Antibiotic Resistance Pattern of Isolated Enterococcus by Standard Techniques

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.

The Prevalence, Isolation, and Antimicrobial Susceptibility Testing of Enterococcus Species From Various Clinical Samples in a Tertiary Care Hospital

“…On the third day, the results of the biochemical tests were analyzed. Enterococcus was identified as grampositive cocci in chains, catalase-negative, bile esculinpositive, and growth in trypticase soy broth with 6.5% NaCl (Mishra et al, 2022).…”

“…The synergistic action of Enterococci with other bacteria increases infection (Afonina et al, 2018;Seputiene et al, 2012;Zaheer et al, 2020). Urinary tract infections are the most common periodic infections resulting from Enterococcus (Marino et al, 2021;Mishra et al, 2022). Post-surgery wound infections rank second.…”
