Morphologic study of the gastric mucosa during Helicobacter pylori infections.

The purpose of the present, study was to underline the importance of the use of SEM in the evaluation of Helicobacter pylori (HP) - Induced gastritis. Gastric biopsies from eleven patients affected by HP infections were examined using Light Microscope (LM), Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM). SEM allowed for the localization of even small groups of bacteria and to demonstrate the many morphologic changes due to the infective phlogosis. The signs of cellular suffering and the relationship between bacteria and microvilli are of particular interest.
