Objective: Enterococci are the second most common cause of nosocomial urinary tract and wound infections, also third most common cause of nosocomial bacteremia. Currently, especially vancomycin-resistant enterococci (VRE) are one of the significant pathogens that cause nosocomial infections and increase mortality, morbidity, and healthcare costs. Therefore prevention and control of the nosocomial VRE outbreaks and epidemiological analysis of the infection are important. Pulsed-Field Gel Electrophoresis (PFGE) is accepted as a “gold standard” method in the molecular epidemiological analysis of enterococcal infections. The aims of this study are to determine the clonal relationship among the nosocomial enterococcal isolates and the rate of cross-contamination between them. Method: Thirty-six Enterococcus strains isolated from hospitalized patients with nosocomial infection in different clinics of Dicle University Hospital between November 2010 and June 2012 were included in this study. A total of 36 isolates were obtained from various clinical samples including urine (n=18), blood (n=6), bronchoalveolar lavage (BAL) fluid (n=5), wound biopsy sample (n=5), vaginal smear (n=1) and catheter tip (n=1). Nine of the thirty-six isolates were VRE. Isolation and identification of the isolates were conducted in the OZET Amac: Enterokoklar hastaneden kaynaklanan uriner
