  1. Epidemiology of colonisation of patients and environment with vancomycin-resistant enterococci.

    Article - En anglais

    Background Vancomycin-resistant enterococci (VRE) have emerged as nosocomial pathogens during the past 5 years, but little is known about the epidemiology of VRE.

    We investigated colonisation of patients and environmental contamination with VRE in an endemic setting to assess the importance of different sources of colonisation.

    Methods Between April 12, and May 29,1995, cultures from body sites (rectum, groin, arm, oropharynx, trachea, and stomach) and from environmental surfaces (bedrails, drawsheet, blood-pressure cuff, urine containers, and enteral feed) were obtained daily from all newly admitted ventilated patients in our medical intensive-care unit (MICU).

    Rectal cultures were obtained from all non-ventilated patients in the MICU.

    Strain types of VRE were determined by pulsed-field gel electrophoresis.

    Findings There were 97 admissions of 92 patients, of whom 38 required mechanical ventilation.

    Colonisation with VRE on admission was more common in ventilated than in non-ventilated patients (nine [24% ] vs three [6% ], p<0.05).

    Of the nine ventilated patients colonised with VRE on admission, one acquired a new strain of VRE in the MICU.

    Of the 29 ventilated patients who were not colonised with VRE on admission, 12 (41%) acquired VRE in the MICU.

    The median time to acquisition of VRE was 5 days (interquartile range 3-8).

    Of the 13 ventilated patients who acquired VRE, 11 (85%) were colonised with VRE by cross-colonisation. (...)
