Figure 2

AB/H/E stained longitudinal section of distal rat colon containing faecal pellets. A sterile mucus layer covers the pellet completely. (a) The mucus layers attached to the faeces cover the entire pellet. (b) A line of bacteria-overgrown mucus penetrates the faecal pellet. (c) Sterile (light blue) and bacteria-overgrown mucus layers (dark blue) can be recognised, mucus production by goblet cells in the lumen is visible. (d) Sterile (‘inner’) and bacteria-overgrown (‘outer’) mucus layers, are recognised in a manner commonly observed in transversal sections.
