Immune response in piglets orally inoculated with B. subtilis-Cap. a Flow chart of inoculation and sample collection time course. Piglets were orally inoculated with B. subtilis-Cap, B. subtilis, inactivated PCV2, and PBS on day 0 and 7. Saliva, nasal swab, feces, and serum were collected as indicated and analyzed by ELISA for PCV2-specific IgA and IgG. b Levels of PCV2-specific IgA in the oral cavity. c Levels of PCV2-specific IgA in the intranasal cavity. d Levels of PCV2-specific IgA in feces. e Levels of PCV2-specific IgG in serum. f The results of neutralizing titer activities of swine serum antibody on day 21 and day 28, expressed as the reciprocal of the highest dilution of serum causing a 50% reduction in fluorescence. Data shown are the means ± S.D. of six samples. * 0.01 < p < 0.05, ** p < 0.01 (compared to the Ctrl group). The error bars represent standard deviations
