Isolation, characterisation and antibiogram of Enterococci from clinical samples

During a one year study 2955 clinical specimens of pus, urine, wound swabs, blood cultures, discharges from fistula, peritoneal aspiration fluid, CSF and sputum were processed to find out the prevalence rate of enterococci. One hundred isolates (3.38%) of Enterococci were obtained which were speciated by conventional methods. The highest incidence was from isolates of urine (43%), pus (40%), wound swabs (11%), and the least incidence was noted in discharges from fistula (2%), blood cultures (2%) and peritoneal aspiration fluid (2%). 98% were Enterococci and among these 88% of the isolates were Enterococcus faecalis. Antibiogram of the isolates were done by Standard disc diffusion method and Vancomycin sensitivity was found to be 95%.
