Experiment 3: Kinetics of total Ig against S. suis serotype 7 in sows after recall vaccination. Blood samples were collected at 3 weeks and 1 week before farrowing from 12 vaccinated and 11 non-vaccinated gilts (that became sows) from Experiment 2 that received a 4th vaccine dose during their 3rd or 4th parity. The vaccination protocol is shown in Fig. 1. Total Ig [IgG + IgM] titers were determined by ELISA. Individual antibody titers are shown with horizontal bars representing mean ± SEM. Arrow indicates the vaccination dose
