Group Pig ID VH: CD, mean (±SD)* Antigen detection in the intestinal
Duodenum Jejunum Ileum
challenged 1 2.9 (0.6) + +++ ++

VH: CD, ratio of villous height to crypt depth.

Antigen detection by immunohistochemical staining: +, 1%–30% of epithelial cells showed staining; ++, 31%–60% of epithelial cells showed staining; +++, 61%–100% of epithelial cells showed staining;-,no epithelial cells showed staining.
