Mouse serum anti-STa and anti-LT IgG antibody titers (in log10) detected from the immunized groups and the control group.(A) Anti-STa and anti-LT IgG antibody titers from the serum samples of mice SC immunized with toxoid fusion 3xSTaN12S-dmLT without adjuvant, or with dmLT (2 μg) or Montanide ISA51 as the adjuvant.(B) Anti-STa and anti-LT IgG antibody titers from the serum samples of mice IP immunized with toxoid fusion 3xSTaN12S-dmLT with 0.2 μg dmLT, 2 μg dmLT or FIA as the adjuvant. Serum samples of the control mice and serum samples collected from mice prior to immunization were included for anti-STa and anti-LT IgG antibody titration. P values were calculated from Student's t-test. Boxes and bars represented means and standard deviations of antibody titers, respectively.
