| OBJECTIVE: Determine the prevalence of Vancomycin-resistant enterococci (VRE) colonizing the intestinal tract of hospitalized patients and define risk factors. MATERIAL AND METHODS: A point prevalence survey of VRE fecal carriage was carried out among patients who stayed at a 600-bed teaching hospital for at least two days. Resistance to vancomycin was detected by the E-test method. Epidemiological data was recorded for all patients included in the study and was used for the risk factor analysis. RESULTS: A total of 128 patients hospitalized for at least two days were enrolled in this investigation. Thirty-nine patients (30.5%) were colonized with vancomycin-resistant enterococci. Twenty-three of the 39 strains were identified as Enterococcus faecium, 13... |

| Vancomycin-resistant enterococci (VRE) are important pathogens involved in nosocomial infections. Colonization precedes infection and the number of colonized individuals is about 10 times higher than the number of infected patients. We examined VRE colonization in two intensive care units from October 2003 to June 2004. Perirectal swab specimens were obtained from all patients, starting on the 5th day after admission, and then weekly. A total of 249 swabs were obtained from 112 patients. Nine patients had VRE-positive swabs, giving a positive rate of 8.0%. The rate of patients colonized by V-R E. faecalis was 1.8% (n=2), 4.5% by V-R E. gallinarun (n=5) and 1.8% by V-R E. casseliflavus (n=2). No V-R E. faeciun was isolated. None of the patients that had... |

| Vancomycin-resistant enterococci (VRE) are important pathogens causing nosocomial infections, and there is reason for concern about their resistance and great ability to spread in hospital environments, especially intensive-care units (ICU). To determine the prevalence of rectal colonization by VRE, and the risk factors associated with their presence, rectal surveillance swabs were taken from patients under treatment in two intensive-care units (one medical and another both medical and surgical) at São Paulo Hospital, over a two-year period. Thirty-three percent of the 147 patients evaluated had VRE. The only significant variable in the logistic regression was the length of stay in the ICU. |
