Genotyping of Helicobacter pylori CagA/CagE strains in gastric mucosa and its association with gastric illness

The aim of this work was associate the presence of the virulence factors of Helicobacter pylori, cagA/cagE, with gastric illness. We found evidence that indicate the contribution of these genotypes with the severity of gastric lesions in patients infected, principally in histological subtypes as atrophic gastritis, and metaplasia.
