Experiment 1: Isotype profile of antibodies against S. suis serotype 7 in vaccinated sows and their piglets. Blood samples were collected 7 weeks and 1 week before farrowing from 25 vaccinated sows to analyze the immune response. The vaccination protocol is shown in Fig. 1. IgM (a), IgG1 (b) and IgG2 (c) titers were determined by ELISA. Randomly selected piglets (n = 125; 5 piglets/sow) from vaccinated sows were sampled at 7 days of age to evaluate titers of IgM (d) IgG1 (e) and IgG2 (f) against S. suis serotype 7. Individual antibody titers are shown with horizontal bars representing mean ± SEM. Values significantly different are shown in the graphs with corresponding P value
