FIG 2.

Mouse serum IgG titers (log₁₀) from the group intramuscularly immunized with 25 μg adhesin MEFA-II (▴), 25 μg adhesin MEFA-II with 0.1 μg adjuvant dmLT (○), or 25 μL PBS (▽). ELISAs using major subunit protein CsvA, CswA, CsvA, CsbA, or LngA as the coating antigen were to titrate mouse serum anti-CS7, -CS12, -CS14, -CS17, and anti-CS21 IgG response, and STa-ovalbumin conjugates to titrate anti-STa IgG titers. Bars represented antibody titer means and standard deviations. *** indicated a P-value of less than 0.0001.
