The distribution of Campylobacter pylori, its prevalence, and its relationship to gastritis and urease activity have been studied in 54 postmortem stomachs. Infection was confirmed by finding C. pylori in a Gram-stained smear of gastric mucus harvested from the entire stomach. Eight tissue specimens were obtained from predetermined sites from each stomach and examined for histologic gastritis and urease activity. Thirty-seven per cent of stomachs were infected, and of these 80% had widespread histologic gastritis. The detection of urease activity provided information on the distribution of the organism and had a high correlation with histologic gastritis. The organism is capable of infecting any area of the stomach. Infection is common and is more prevalent in Polynesian subjects (60%) than in Caucasians (19%).
对54例尸检胃组织进行了幽门螺杆菌的分布、感染率及其与胃炎和尿素酶活性关系的研究。通过在取自整个胃部的胃黏液革兰染色涂片中发现幽门螺杆菌来确诊感染。从每个胃部的预定部位获取8个组织标本，检查其组织学胃炎和尿素酶活性。37%的胃部受到感染，其中80%有广泛的组织学胃炎。尿素酶活性的检测提供了该菌分布的信息，且与组织学胃炎高度相关。该菌能够感染胃的任何部位。感染很常见，在波利尼西亚人（60%）中比在白种人（19%）中更普遍。
