title: Enterococcus spp. in a single blood culture: bacteremia or contamination?
abstract: We retrospectively evaluated adult cases with Enterococcus spp. in 1 blood culture (BC) (1/1/2010-12/31/2015; n=294) and stratified them into bacteremia or contamination. Contamination frequency was similar in community versus hospital-onset, E. faecalis versus E. faecium, and number of BC drawn per day. Contamination predictors were vancomycin-resistance, ampicillin-resistance, commensal organism copresence, and nonurinary/abdominal sources.
