[The importance of nitric oxide (NO) in the development of Helicobacter pylori infection]

In this work we discussed selected questions about the Helicobacter pylori pathogenesis linked with the components of cell-walls as well as with toxins and enzymes externally secreted by this bacteria. We also paid attention to some theories which try to imperf the damaging effects of the bacteria on the mucosa of the upper part of the alimentary canal, specifically underlining the possible link between the Helicobacter pylori infection and the increase of the concentration of cytotoxically acting nitric oxide (NO).
