许多研究者证实了急、慢性胃窦炎和十二指肠溃疡与幽门弯曲菌有关。诊断幽门弯曲菌的感染,常由内窥镜检查取得活组织标本,经分离细菌或以切片染色作鉴定。两种方法都较费时。因此,用快速试验方法鉴别幽门弯曲菌感染,有助于迅速拟定治疗方案。幽门弯曲菌有很高活性的内源性尿素酶,这个性质已被用于诊断。几个研究者曾用这个性质鉴定幽门弯曲菌,方法是将取自胃窦的活组织标本置Christensen 尿素肉汤中,观察颜色的改变,以证明尿素酶的存 Many researchers have confirmed that acute, chronic gastritis and duodenal ulcer associated with Campylobacter pylori. Diagnosis of Campylobacter pylori infection, often obtained by endoscopy biopsy specimens, isolated bacteria or slice staining for identification. Both methods are more time-consuming. Therefore, the rapid test method to identify Campylobacter pylori infection, help to quickly develop treatment options. Campylobacter pylori has a highly active endogenous urease, a property that has been used for diagnosis. Several researchers have used this property to identify Campylobacter pylori by placing the biopsy specimen taken from the antrum in Christensen’s urea broth and observing the change in color to demonstrate the presence of urease
