- Helicobacter pylori-like bacteria in the lumen, as curved, spirochete-like bacteria, generally in the superficial mucus layer and along microvilli of epithelial cells.
- Associated inflammation, typically a chronic inflammatory infiltrate with germinal centers (follicular gastritis), and plasma cells in lamina propria.[notes 2] There should be at least 3 plasma cells facing each other to make a diagnosis of chronic gastritis.
Chronic gastritis without H. pylori-like organisms should be described as non-specific:
|Mild chronic gastritis, which is non-specific.|
Negative for H. pylori-like organisms on H&E stain.
