[Campylobacter pyloridis (Cp) infection of gastric mucosa in the high and low risk areas of gastric cancer in Liaoning province].

Gastric biopsies in 690 subjects from the high and low risk areas of gastric cancer were examined for identification of Cp in the gastric mucosa by Warthin-Starry, Gimenez and Gram's stains. The result showed that the positive rate was 60-62% in the high risk area whereas it was only 12.6% in the low risk area in Liaoning province. 81-85% of the positive subjects had active chronic gastritis including chronic superficial and atrophic gastritis. The result indicates a close correlation between the active chronic gastritis and Cp infection. Therefore, control of the Cp infection in the gastric mucosa is very important for lowering the incidence of chronic gastritis, a well known precursor of gastric cancer.
