Malnourished pigs had significantly reduced total Ig concentrations in serum and small intestinal contents (SIC) post-VirHRV challenge. Total IgM (A), IgG (B), and IgA (C) concentrations in serum. Total IgM (D), IgG (E), and IgA (F) concentrations in small intestinal contents. Significant differences (*p < 0.05, **p < 0.01, ***p < 0.001) are indicated. Gnotobiotic pigs were transplanted with human infant fecal microbiota (HIFM) at 4 days of age. Pigs were fed deficient diet (Deficient) and sufficient diet (Sufficient). All the pigs were orally vaccinated twice with AttHRV on post transplantation day (PTD) 7 and 17, challenged with virulent human rotavirus (VirHRV) on PTD24/PVD17(7)/PCD0 and euthanized on PTD31/PVD24(14)/PCD7. PVD, post 1st (2nd) vaccination day; PCD, post-challenge day.
