Area occupied by type I, type III, and total fibrillar collagen fibers (μm²). 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. Photomicrograph of the area occupied by type I collagen fibers (yellow arrow) in control group and 2314 at 90-days post infection; by type III collagen fibers (green arrow) in group 2314 at 90- and 120-days post infection; and of total fibrillar collagen (black arrow) in group 2903 at 90- and 120-days post infection (Picrosirius Red staining, 20× magnification, scale bar = 25 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.
