Helicobacter pylori is a helix-shaped Gram-negative bacterium that colonises the stomach. This bacterium is now known as the major cause of ulcers and gastritis H. pylori (Helicobacter pylori) are spiral shaped bacteria. H. pylori bacteria are unique because they produce the enzyme urease that allows the bacteria to live in the harsh environment of the stomach. The urease enzyme it produces reacts with urea to form ammonia that neutralizes enough of the stomach's acid to allow the organisms to survive in the tissues

The soil beneath our feet is rich with millions of bacteria - some harmful, some good. This is the story about the good guys - Bacillus spore-forming probiotics. Bacillus probiotics are spore-forming bacteria that are heat stable and able to survive passage through the acidic stomach & make it to the gut where they offer unique health benefits H. pylori may lead to changes in the cells of your esophagus or stomach. The cells are changed into intestine cells. This is a condition called intestinal metaplasia that increases your risk for cancer of the esophagus or stomach.
