H. Pylori is a bacteria that actively suppresses the production of stomach acid. It has two cell walls, which makes it twice as difficult for the body to fight off. Itâs also a parasite, and is easily passed from person to person via saliva.he Dangers of H. Pylori. H Pylori infections lead to many larger health problems. Itâs tied to serious health hazards such as irritable bowel syndrome (IBS), chronic heartburn, gastritus, and gastroesophageal reflux disease (GERD).
Scientists studying the genetics of H. pylori have found different strains (types) of the bacterium. Some strains of H. pylori appear to be more prone to cause ulcers and stomach cancer. Further research in this area may help doctors to intelligently select those patients who need treatment. Vaccination against H. pylori is unlikely to be available in the near future.
