Helicobacter pylori bacteria, coloured scanning electron micrograph (SEM). H. pylori is a Gram-negative spiral-shaped bacterium found in the mucus lining of the stomach. It causes gastritis, and is also the most common cause of stomach ulcers. It may also be a cause or co-factor for gastric cancer as its presence increases the risk of developing stomach tumours.

Martin Oeggerli Fibrin is a protein created by the body that works with platelets in the blood to clot a wound. As they reach the wound site, they attach themselves to fibers, and create a mesh.
