Serum levels of PRRSV- and CSFV-specific antibodies in different treatment groups. A Serum antibody levels against CSFV. The antibody blocking rate of a test sample greater than or equal to 40% was considered positive. B Serum antibody levels against PRRSV. S/P ratios of greater than 0.4 were considered positive. C The titer of serum neutralizing antibody against CSFV. D The titer of serum neutralizing antibody against PRRSV. Note: the bars are the respective standard deviation. Data are shown as the mean ± SD, and different letters (a, b, c) and (*) above the bars indicate significant differences (P < 0.05) as in Fig. 1; (ns) indicates no significant differences among S + PRRS, S-PRRS, PRRS-S and control groups within different immunization time (P > 0.1)
