Immunohistochemical staining results showed the degree of HP colonization in the gastric mucosa. (A) A concentrated amount of HP bacilli (black arrow) was found on the surface of the gastric mucosa, the gastric pits, and the epithelial surface of the glandular ducts (severe). (B) A medium amount of HP bacilli was found on the surface of the gastric mucosa, the gastric pits, and the epithelial surface of the glandular ducts (moderate). (C) Small amounts of HP bacilli were found on the surface of the gastric mucosa, the gastric pits and the epithelial surface of the glandular ducts (mild).
