title: Additive effect of Enterococcus faecium on Enterococcal bloodstream infections: a 14-year study in a Swiss tertiary hospital.
abstract: We investigated whether an increase in enterococcal bloodstream infections (BSIs) depends on the emergence of Enterococcus faecium in an area with low vancomycin-resistant enterococci prevalence. From 1999 to 2012, a linear increase in E. faecium BSI rates (0.009 per 1,000 patient-days per year; P < .001) was noted. Enterococcus faecalis BSI rates remained stable.
