• Helicobacter pylori

  definition

  Helicobacter pylori is…

  Bacterium that causes gastric ulcers and which, in chronic infections, can contribute to the development of gastric carcinoma. It was previously thought that the stomach’s acidic environment kills all bacteria. However, Helicobacter pylori invades the gastric mucosa, where it produces ammonia, a strong base, which neutralizes the stomach acid in the bacterium’s vicinity.
