[Electron microscopic observations of Campylobacter pyloridis in chronic gastritis].
Gastric biopsies from 150 cases of chronic gastritis were studied by electron microscopy. The infection rates of Campylobacter pyloridis (CP) were 95.3% (85 cases) and 69.2% (65 cases) in superficial gastritis and atrophic gastritis respectively. A close relationship was seen between quantity of the bacteria and activity of the disease. Electron microscopy showed that CP usually damaged the columnar and pit cells of the stomach, resulting in necrosis and active inflammation of the mucosa, and infection of CP might act as a very important pathogenic factor of chronic gastritis.
