Fig. 6. Biofilm-positive human colonic polyps demonstrate invasion of bacteria into the mucosa.
×63 confocal images of human colonic tissues fixed in Poloxamer showing regions of biofilm positivity using Eub (green) probes to identify bacteria. a Patient polyp sample HTA11_1429_20_2013 with (b) normal ascending colon. c Normal ascending colon with (d, e) patient polyp sample HTA11_1391_20_1011. White arrows indicate invaded bacteria. White dotted lines represent epithelial borders in normal colon. Scale bars = 50 μm.
