Growth rates of
UW7709 and D32 in a mouse bacteremia model. Eight female BALB/c mice were infected via the tail vein with E. faecalis strains UW7709 or D32 (5 × 108 CFU). After 48 hours, mice were sacrificed and bacterial counts in (A) liver, kidneys and spleen, as well as, in (B) blood were determined. Data represent the individual bacterial burdens and the geometric mean values. Asterisks indicate significant P values calculated by using Mann–Whitney test (*P < 0.05, ***P < 0.0005).
