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.
2) What are the effects of H pylori
in the stomach
Helicobacter pylori are pathogens that cause disease in the gastric intestinal track. Scientists are unsure of how these pathogens are spread, but they are assuming that they enter the stomach through contaminated food and water. We went over the illnesses that Helicobacter pylori can cause in class. One of the major one is peptic ulcers and stomach cancer in some cases. I only imaging that how difficult it is to get rid of this particular bacteria, because of the protective enzymes they produce. The immune response mechanism is inactive toward H. pylori, because they are protected against defense systems of the body. Disease causes by these bacteria are mostly found in people living in crowded environment, poverty, and limited sanitation.
