Experiment 2: Isotype profile of antibodies against S. suis serotype 7 in vaccinated and non-vaccinated gilts and their piglets. Blood samples were collected 1 week before farrowing from 14 vaccinated and 15 non-vaccinated gilts 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 = 145; 5 piglets/sow) from vaccinated and non-vaccinated gilts 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 graph with corresponding P value
