Figure 8

Proportion of intraepithelial lymphocytes (IELs) in 100 epithelial cells, mast cells, and TGF-β-immunoreactive cells (TGF-β-IR) per mm². Data represented in box plots (median with 25 to 75 percentile), whiskers (2.5 to 97.5 percentile), and mean (+) (n = 6). *p < 0.05; **p < 0.01; ***p < 0.001. Representative photomicrograph of IELs in the control group and 2314 at 90-days post infection (black arrows; HE staining, 40× magnification, scale bar = 15 µm, Olympus BX50); mast cells in group 1655 at 90- and 120-days post infection (black arrows; blue toluidine staining, 40× magnification, scale bar = 15 µm, Olympus BX50); TGF-β-IR of the control group and 2903 at 120-days post infection (yellow arrows; immunohistochemistry, 40× magnification, scale bar = 15 µm, Olympus BX50). CG, control group. 2903: group infected with MHOM/BR/1975/M2903. 2314: group infected with MHOM/BR/2003/2314. 1655: group infected with MHOM/BR/2000/1655.
