Abstract
Helicobacter pylori: review of physiologic and patologic aspects.Helicobacter pylori is a spiral-shaped bacterium, that lives only in the human stomach. Although the relationship of the bacillus in the epithelium has been since ancient because most of the population is colonized, only about 10% of infected people develop certain diseases, including duodenal ulcer, stomach adenocarcinoma and lymphoma MALT. In recent decades, research on Helicobacter pylori has increased, and little by little, has dazzled more about the pathophysiology of this organism, as the presence of genes involved in pathogenicity vacA, cagA, babA and sabA thereby indicating that is just a completely harmless bacteria, but neither of the major pathogen in stomach epithelium. Through this review is to cover some aspects of the bacteria, their relationship and benefits to the host and the pathological processes that can trigger their actions. (MÉD.UIS. 2011;24(3):275-82).Key Words: Helicobacter pylori. Peptic ulcer. Lymphoma MALT. Lymphoma. B-Cell. Marginal Zone.
