[Helicobacter pylori: clinical pictures of an infectious disease with pathogen persistence].

It is the aim of this paper to provide survey of the very fast developing field of medical research on Helicobacter pylori which includes as different branches as gastroenterology, pharmacology or microbiology. After examination of the several diseases, pathological mechanisms, the diagnostical techniques and the therapeutical regimens, the authors of this study favorize an early indication for eradication of helicobater pylori. Since research on Helicobacter pylori is divided into many fields, there is the attempt to come to a clear and more rational point of view concerning therapeutical strategies and management of the infection. It is another focal point to emphasize the important role that chronical gastritis induced by Helicobacter pylori plays as an important risk factor for gastric carcinoma.
