After some years of discussion Helicobacterp pyloriis accepted has been accepted eas the etiologic agent of type B gastritis and peptic ulcers. Thus, these pathological entities could be treated with antibiotics. However, the discussions still persist about the possible relation between H. pylori and gastric cancer. This hypothesis is based on documented serologic evidence of previous infection with this bacteria and the increase the risk for gastric cancer, as wellas reports showing remission of some gastric lymphomas with anti H. pilori treatment. H. pylori has also been indicated as the causative agent of non-ulcerative dyspepsia, but the nature of this disease inders the early diagnosis and the possible linkage with Helicobacter, Nevertheless, the wide spectrum of polimorphic manifestations on this infectious agent increase the importance of new knowledge of this topic.
