IL-10 (A), IL-12 (B), and IFN-γ (C) response of human PBMCs of six distinct individual donors to stimulation with RPMI medium and five bacterial strains. The values are expressed as the mean ± SEM in pg/ml for cytokines and in percentages for IL-10/IL-12 ratio (D). Different asterisks (*) indicate significant differences (*, P < 0.05; **, P < 0.01; ***, P < 0.003).
