Follow-up analysis and histopathological study of gastric mucosa in patients with infection.

Objective: To investigate the histomorphological characteristics of the gastric mucosa and the prognosis in patients with infection.

Methods: Progressive damage to the gastric mucosa was examined by immunohistochemistry in 2294 patients with infection and follow-up information was analyzed.

Results: initially colonized the mucus layer covered by the gastric mucosa epithelium, then selectively adhered to and destroyed the surface mucus cells causing intra-gastric and extra-gastric lesions.
