Abstract
The recent attention that focused on enterococci is likely to continue in the future. The ability of enterococci to colonize the gastrointestinal tract, plus the many intrinsic and acquired resistance traits means thai: these organisms are given an excellent opportunity to become secondly invaders. During the study period from March 2003 to July 2004 and out of 350 samples 16 enterococci were isolated representing 10.6% of all nosocomiaJ infections. UTI are common than wound infection from which enterococci were isolated. The ” overall incidence of vancomycin resistance mong enterococci” was 56%. VRE was isolated from 6% all nosocomial infections enterococci including VRE were isolated both in pure 62.5% am’, in mixed culture 37.5%mostly among gram negative bacilli. Among several factors analyzed, we found that the most important factors that were associated with VRE infections included prolonged hospitalization, prolonged intake of third generation cephalosporin and vancomycin as well as gastrointestinal colonization. After performing an epidemiologic study on intensive care unite patients, we confirmed the role of the health care personnel in the nosocomial transmission of the organism which necessitates isolation of patients and implementation of strict infection control measures to control the spread of infection among patients. After performing biochemical reactions we can differentiates two types of strains pathogenic highly resistant to vacomycin E.faecalis and E. facieum and low resistance strains E. casseliflavus and E. gallinarum.
