Bacterium in human appendix, coloured scanning electron micrograph (SEM). A single large bacterium (pink) is present on the surface of the appendix epithelium. The epithelium is covered in microvilli typical of the gut. Research suggests the appendix may be used as a reservoir of healthy bacteria for the rest of the gut. Magnification: x13000 when printed at 10 centimetres wide.
