Helicobacter pylori

Helicobacter pylori is strongly associated with inflammation of the stomach and is also implicated in the development of gastric malignancy, peptic ulcers, and gastric lymphomas in humans. Helicobacter pylori can exist in a number of locations: in the mucus, attached to epithelial cells, or inside of vacuoles in epithelial cells, where it produces adhesions that bind to membrane-associated lipids and carbohydrates in or on epithelial cells.1-3

The most reliable method for detecting H. pylori infection is a biopsy during endoscopy histologic examination and detection by immunohistochemistry. Immunohistochemical staining of H. pylori on the surface of gastric mucosa is a valuable tool for identification of H. pylori infections.1-3
