FIG. 5.
Opsonization for intracellular killing of E. faecalis strains OG1SSp by AS44–331-specific antiserum. Strains containing pMSP7517 express Asc10, and control strains contain pMSP3535. Open bars represent bacterial counts at 0 min, and solid bars represent counts at 120 min. Data represent the average of five independent experiments. Error bars, SEM. ∗, P < 0.05 by the Student t test when compared with all other bacterial counts at 120 min. There was no significant difference among bacterial counts at 0 min.
