C Log 10 transformed peritoneal bacterial colony forming units. D Probability of Survival in the days following CLP with blockade as noted. Data as mean ± SD. Analyzed by 2-way ANOVA. * = p < 0.05 for comparisons between two groups. P Int = Significant Interaction between Blockade and Education, P Block = Significant Effect of Treatment (CLP + antibody blockade), P Edu = Significant Effect of Control vs Immune Education.
