Survival and bacterial load of BALB/c mice after intraperitoneal infection with <i>E</i>. <i>faecalis</i> strains.

<p>Survival after infection with 1.3 x 10⁹<i>E</i>. <i>faecalis</i>. P = 0.0096 EF 12030 wild-type vs. Δ<i>bgsA</i> determined by the log-rank test (A). Bacterial counts 3 h and 12 h after i.p. challenge (inoculum 2.0 x 10⁹ cfu per mouse, 14 mice per group). The bacterial load is expressed as the log₁₀ (cfu) per ml ± SEM (B). P > 0.05 EF 12030 wild-type vs. Δ<i>bgsA</i> vs. Δ<i>bgsB</i> at 3 h and 12 h by 2-way ANOVA.
