Clonal spread and horizontal transfer in the spread of vancomycin resistance genes were investigated. Multiplex PCR, pulsed-field gel electrophoresis (PFGE), hybridization of enterococcal plasmids with the vanA and vanB probes, and sequencing of a fragment of vanB were used in the analysis. Before May 1996, 12 vancomycin-resistant Enterococcus faecium (VRE)(More)
The emergence of hospital acquired infections with bacteria resistant to antimicrobials such as vancomycin resistant enterococci (VRE) has become a worldwide concern. In hospitals in the United States, VRE have spread quickly and currently account for eve
The objective of this study was to characterize the overgrowth and susceptibility of Enterococcus faecium, compared with that of other enterococci, in the feces of patients with hematologic malignancy. During a 52-week period, surveillance samples of feces were cultured weekly. Three hundred thirty-three samples were obtained from 92 patients. E. faecium(More)
The purpose of our study was to determine retrospectively the risk factors for the acquisition of Enterococcus faecalis vs E. faecium bacteraemia, as well as the clinical outcomes of these patients. 62 patients with Enterococcus faecalis bacteraemia were compared to 31 patients with E. faecium bacteraemia. Haematologic malignancies, neutropenia, high-risk(More)
