Fig. 2

The antibody response of (a) S. suis 2 (b) rSao-specific IgG in the serum of piglets from sows with or without (n = 5 each) prepartum immunization with inactivated S. suis 2 + rSao. Data are represented as Mean ± SEM of peak absorbance values as determined by indirect ELISA performed on diluted (1:500) serum samples. S/P ratio = (sample – Nˉx) / (PCˉx – NCˉx). Differences between groups were analyzed by Student’s t-test, statistically significant difference (P < 0.05) in comparison to the control group
