What is the Role of Helicobacter pylori in Gastric Disorders?
Helicobacter pylori is a gram-negative bacterium implicated in various gastric disorders, including chronic gastritis, peptic ulcers, and gastric cancer. Histologically, H. pylori infection is identified by the presence of the bacteria on the surface of the gastric epithelium, often accompanied by a dense inflammatory infiltrate. Special stains, such as Giemsa stain or immunohistochemical techniques, can be used to visualize the bacteria.
