Background: The emergence of Enterococcus as an important nosocomial pathogen is mainly attributed to its inherent resistance to commonly used antibiotics and now in recent times, it has acquired resistance to other available therapeutic options as well. Materials and Methods: Enterococcus isolates from clinical samples received in the department of microbiology over a period of 1 year were included in the study. Isolates were identified and species determined by standard methods. Antibiotic susceptibility test was done by Kirby Bauer disc diffusion test. Epsilometer test was done to determine the minimum inhibitory concentration for vancomycin. Results: A total of 145 Enterococcus isolates were obtained; 73 (50.3%) isolates were identified as Enterococcus faecalis, 69 (47.5%) Enterococcus faecium, 2 (1.3%) Enterococcus durans and 1 (0.68%) as Enterococcus gallinarum. Most of the isolates were from urine samples (125, 86.2%); followed by pus (16, 11.03%). Vancomycin resistance was seen in 14 (9.6%) isolates while linezolid resistance was seen in 8 (5.5%) isolates. Conclusion: E. faecalis is the most common clinical species isolated from clinical samples and the emergence of linezolid-resistant enterococci from the hospital is a matter of concern as till now it is considered to be the last resort for treatment in patients infected with vancomycin-resistant enterococci.
