Fecal cylinder with DAPI stain

A fecal cylinder with DAPI stain. Multiple single microscopic fields taken at magnification of x100 have been used to create a composite overview. The center of the cylinder contains no leukocytes and the bacteria are homogeneously distributed. The cylinder has no mucus cover but instead the "germinal" zone is infiltrated by many leukocytes (arrows). The findings are typical for ulcerative colitis.
