Intestinal HRV specific-IgA antibody and total IgA responses and correlation between small intestinal HRV IgA antibody titers and mean diarrhea scores at post-challenge (PID34/PCD7). Geometric mean titers (GMT) of HRV specific-IgA (A) and total IgA (B) antibody titers in intestinal contents of Gn pigs vaccinated with AttHRV with or without LGG + Bb12 probiotic colonization at post-HRV challenge (PID34/PCD7)(one-way ANOVA followed by Duncan's multiple range test on log₁₀ transferred titers, *P < 0.05). Correlations between SIC HRV IgA antibody titers and mean diarrhea scores (C and D) were determined using Spearman correlation coefficient. Error bars indicate SEM. PID-Post-inoculation day; PCD-Post-challenge day. SIC-Small intestinal contents; LIC-Large intestinal contents.
