[Long-term studies of colonization of the gastric mucosa by Campylobacter pyloridis].

Multiple biopsy specimens of gastric mucosa of 15 patients taken at different intervals with an observation period of 4 to 20 years were evaluated. Histological examination revealed superficial gastritis in most cases without radical and progressive destruction of the mucosa and in all but one case the presence of CLO was demonstrated with varying degree of intensity. No evidence was found for causal relationship between bacterial colonization and inflammation.
