The shape of the H. pylori bacteria is spiral. These bacteria survive the stomach by activating their cytoplasm to produce an enzyme that neutralizes the stomach acid. This enzyme is known as urease, which then changes the urea into carbon dioxide and ammonia. The ammonia is secreted around the cell to protect it from being phagocytized. These two enzymes work together to neutralize the strong stomach acid called hydrochloric acid. For the bacteria to colonies the stomach, this process has to be repeated itself continuously. The bacteria cell becomes vulnerable to the stomach acid, when enough urea and ammonia are not produce by it.
