RESUMO

Ultrastructural examination of gastric mucosa from Helicobacter pylori-infected gnotobiotic piglets identified four general adherence patterns comparable to those observed in human patients. Intimate associations between the bacterial and mucosal cell membranes, including cuplike invaginations and adherence pedestals, were present and were accompanied by alterations to microvilli and cell membrane morphology.
