[Effect of Campylobacter pyloridis and other parietal microflora on gastric epitheliocytes in peptic ulcer and following vagotomy].

Using light and transmission electron microscopy, the authors studied the effect of vagotomy on the interaction between the parietal microflora (Campylobacter pyloridis, in particular) and gastric epitheliocytes in peptide ulcer patients (n = 80). Campylobacter pyloridis abundant in pyloric and antral portions of the stomach following vagotomy was found in still increasing quantities. Ultrastructurally, there were alterative changes in parietal microflora-contacting epitheliocytes both in peptic ulcer and following vagotomy.
