PbsP-based immunization protects against lethal CC17 GBS infection in mice. (A) Mice were immunized with recombinant PbsP fused to glutathione-S-transferase (GST-PbsP) or with GST as a control and challenged i.v. with 1 × 108 CFU of wild-type CC17 strain BM110. *p < 0.05 by Kaplan-Meier analysis. Shown are the cumulative results of two experiments, each involving 8 mice per group. (BD) Effects of PbsP immunization on organ bacterial burden after i.v. challenge with 1 × 108 CFU of BM110. **p < 0.01 by the Mann-Whitney U test; ns, non-significant. Shown are cumulative results from 2 experiments, each involving 6 mice per group.
