Epidemiology of Vancomycin-Resistant Enterococci in Canadian Hospitals (CANWARD Study, 2007 to 2013)

ABSTRACT Of 1,927 Enterococcus species isolates collected across Canada from 2007 to 2013, 80 (4.2%) were identified as vancomycin-resistant enterococci (VRE). VRE infections during this time tripled in Canadian hospitals, from 1.8% to 6.0% ( P = 0.03). All VRE were Enterococcus faecium, with 90% possessing vanA . The prevalence of vanB decreased from 37.5% in 2007 to 0% in 2013 ( P
