Abstract
Objective: The aim of Present study was undertaken to evaluate the prevalence of Group D Streptococci or Enterococci isolates, isolated from the various clinical samples and to find out their Antimicrobial sensitivity Pattern.
Materials and Methods: A total of 2915 clinical samples or specimens (Urine, pus, wound swabs, blood cultures, discharges from fistula, peritoneal aspiration fluid, CSF and sputum) from both OPD and IPD of our hospital were received in our department. All samples were processed according to CLSI guidelines. Antimicrobial susceptibility test was done by Kirby Bauer's disc diffusion method. Antimicrobial drugs used are Amoxy-clav, Gentamicin, Azithromycin, Ciprofloxacin, Moxifloxacin, Cefepime + Tazobactum, vancomycin, Linezolid and Teicoplanin.
Results: Out of 2915 clinical samples, a total of 80 isolates (6.62%) of Enterococci were obtained. The highest incidence was from isolates of urine (4.30%), Pus (1.32%), wound swab (0.57%) and the least incidence was from fistula (0.08%), Blood culture (0.08%) and Peritoneal aspiration fluid (0.08%). Majority of Enterococci, 88% of the isolates were Enterococcus faecalis. Antimicrobial sensitivity pattern of the isolates showed 97% sensitivity to vancomycin and 100% sensitivity to the Linezolid and Teicoplanin. Conclusion: Enterococci have emerged as a common cause of Hospital and Hospital acquired infection and incidence to the resistance of antibiotics is increasing. So Irrational and indiscriminate use of antibiotic can be avoided and antibiotic can be used after drug sensitivity testing.
