| Sumario: | Helicobacter pylori is a Gram-negative bacterium that colonizes the gastrointestinal tract of humans, mainly the gastric mucosa. These bacteria colonize around half of the world¿s population, although their prevalence varies among geographical regions within a country, as well as between rural and urban areas, due to the socio-economic conditions, age and population ethnicity [1, 2]. Even though 80% of the infected population is asymptomatic, persistent infection by these bacteria causes chronic inflammation of the mucosa, which manifests as gastritis that can develop to chronic atrophic gastritis, intestinal metaplasia, dysplasia, and finally, gastric cancer [3¿5]. |
