Live Combined Bacillus subtilis and Enterococcus faecium Ameliorate Murine Experimental Colitis by Immunosuppression

Figure 3

Infiltration of macrophages into the lower segments of colons from normal, control, and Medilac-S rats. Representative images of lower segments of colons tissue stained with DAPI (blue) and F4/80 (red). The result has shown that rare macrophages labeled with F4/80 infiltrated in the intestinal tissue in the normal group. But after establishment of murine model of colitis, a few macrophages infiltrated into the local intestinal. And the treatment with Medilac-S reduced the infiltrated macrophages significantly.
