Endoscopic biopsies from the duodenal cap and prepyloric areas of 25 patients have been examined with the scanning electron microscope. Eleven patients had duodenal ulceration. Bacteria are related only to the surface of gastric type epithelial cells whether these cells are located at areas of gastric metaplasia in the duodenal bulb or in the pre-pyloric region of the stomach. The bacteria are not associated with the surface of intestinal type epithelial cells. The bacteria are absent from the biopsies of those patients with a normal stomach and duodenum. Of those patients with duodenal ulceration, 73% have bacteria related to the epithelial surface. The bacteria are of two morphological types - a kidney shaped bacillus and an S-shaped bacillus.
对25例患者十二指肠球部和幽门前区的内镜活检组织进行了扫描电子显微镜检查。11例患者有十二指肠溃疡。细菌仅与胃型上皮细胞表面相关，无论这些细胞位于十二指肠球部的胃化生区域还是胃的幽门前区域。细菌与肠型上皮细胞表面无关。胃和十二指肠正常的患者活检组织中没有细菌。在十二指肠溃疡患者中，73%的患者上皮表面有相关细菌。细菌有两种形态类型——肾形杆菌和S形杆菌。
