FIG. 3.

Immune responses to Salmonella-specific antigens in mice orally inoculated with the Salmonella vaccine candidate with or without mucosal adjuvant strains. Serum Salmonella-specific IgG (A), IgA (B), and IgG1 and IgG2a (D) and fecal Salmonella-specific sIgA (C). Group A to G values refer to Fig. 2 and Table 2. The data shown are the mean values for all mice in each group, and error bars demonstrate standard deviations (SD). Asterisks indicate significant differences between group A to F values (*, P < 0.05; **, P < 0.01) and those of the control group.
