Caption

Gastric ulcer. Artwork of a gastric (stomach) ulcer caused by Helicobacter pylori (formerly Campylobacter pyloridis) bacteria (green). The bacteria are destroying the epithelial cells (pale pink) that line the stomach creating an ulcer (lower right). White blood cells (lymphocytes, lower centre) are moving into the infected area. Normally the epithelium is protected from digestion by stomach acids through the secretion of mucus (spheres) from specialised cells (such as at upper left) and rapid cell replacement. However H. pylori damages cells and disrupts these processes resulting in gastric ulcers.
