Abstract
Vancomycin-resistant Enterococcus faecium (VREFm) has become one of the most prominent hospital outbreak micro-organisms over the last decade, including renal wards. 1 Beltrami E.M. Singer D.A. Fish L. et al. Risk factors for acquisition of vancomycin-resistant enterococci among patients on a renal ward during a community hospital outbreak. Am J Infect Control. 2000; 28: 282-285 Abstract Full Text Full Text PDF PubMed Scopus (30) Google Scholar In 2000 in The Netherlands, there was an outbreak of VREFm at the University Medical Centre Utrecht (UMCU), predominantly in the dialysis department. During the outbreak several genetically different VREFm strains co-circulated among patients at the UMCU in parallel with the outbreak clone. Hygienic measures successfully controlled this VREFm. 2 Mascini E.M. Troelstra A. Beitsma M. et al.
