Fig. 3. Impact of fermented milks on 7-day Dextran Sodium Sulfate (DSS) colitis in mice. (A) Body weight loss (% of initial) seen in healthy animals receiving the PBS control (PBS),
and in those receiving the milk matrix (Milk), Mix1, Mix2 and Mix1-fermented with Propionibacterium freudenreichii CB 129 (Mix1-Pf). (B) Colon length in cm. (C) Myeloperoxidase
activity in arbitrary units (AU). (D) Serum Amyloid A protein (SAA), expressed in mg/mL. (E) Representative histological colon sections (May-Grünewald and Giemsa staining) from
mice treated under the various conditions. Bars represent 200 mm. The data represent the mean (±SEM) of 10 mice/group, (*p < 0.05 versus) the PBS group.
