H. pylori (previously known as Campylobacter pyloridis) is a type of bacterium that infects the stomach lining, often leading to the development of peptic ulcers. The transmission of H. pylori can be passed from person to person through direct contact with saliva, vomit, or fecal matter. Additionally it can also be spread through contaminated food and water.
Typically the infection is contracted during childhood and goes undiagnosed until symptoms of peptic ulcers appear. H. pylori infection has a global presence, by affecting about half of the world’s population.
The H. pylori bacteria has a substantial effect on human health, and if left untreated it can develop open sores on the inner lining of the stomach or on the upper portion of the small intestine. The development of these peptic ulcers can lead to various types of complications, i.e perforation, bleeding, and in some cases increase the risk of stomach cancer.
