Mortality of BALB/c, IFN-γ GKO, Nramp1−/−, and 129/svEvTac mice after intravenous infection with E. faecalis strains. Each bar represents the cumulative percent mortality for day 0, 5, 10, 15, or 20 postinfection. The medium used for bacterial growth (rabbit serum or BHI broth) is shown below the graph. In initial infections with BALB/c mice, strains MGH-2, JH2-2, and 418 were grown in rabbit serum while E. faecalis strains DS16C2 and OG1X were grown in BHI prior to injection for the reasons given in Materials and Methods. In subsequent experiments with IFN-γ GKO, Nramp1−/−, and 129/svEvTac mice, E. faecalis MGH-2 and JH2-2 were grown in rabbit serum before injection.
