FIG. 2.

Effect of an 8-day course of administration of either Lactobacillus rhamnosus Lcr35 or Escherichia coli Nissle on intestinal carriage of vancomycin-resistant Enterococcus faecium (VRE). All mice received vancomycin (250 μg/ml) in drinking water for 14 days, and VRE gastric inoculation was performed on D7. On D14, vancomycin was stopped and mice received once daily either probiotic (•, Lcr35, 10⁸ CFU; ○, E. coli Nissle, 10⁹ CFU) or saline (▴), for 8 days. Stool VRE levels were quantified over a period of 4 weeks.
