在作胃镜及活检的半数患者中,胃内有细菌定居,并发现细菌侵袭与相关的组织学改变之间有一致性。作者在135个活检标本中发现有小的弯状及S形杆菌。细菌紧邻表面上皮,可在胃小凹内及胃小凹间。分布为连续性、斑点状或局灶性。用苏木精伊红染色难以察见,但用Warthin-Starry银染色后可清 In half of patients who underwent endoscopy and biopsy, there was bacterial colonization in the stomach, and there was consistency between bacterial invasion and associated histological changes. The author found in 135 biopsy specimens of small curved and Fusobacterium. Bacteria close to the surface of the epithelium, can be in the foveola and gastric cavity. Distribution of continuity, spotty or focal. Difficult to see with hematoxylin-eosin, but clear with Warthin-Starry silver stain
