分离并鉴定了一种新的定植于Wistar和Holtzman大鼠结肠粘膜的螺旋杆菌。该菌为革兰氏阴性菌，细胞呈杆状，两端尖，原生质圆柱体被周质纤维包裹。过氧化氢酶和氧化酶阳性，快速水解尿素，对甲硝唑敏感，对头孢噻吩和萘啶酸耐药。这种新的微生物是微需氧的，在42°C下生长，这一特征使其与其他两种小鼠肠道定植者肝螺杆菌和小鼠螺杆菌区分开来。根据16S rRNA序列分析数据，新菌株被鉴定为与H.肝这种细菌被命名为幽门螺杆菌。模式菌株为菌株LRB 8581（= ATCC 700114）。
A newHelicobacterspecies that colonizes the colonic mucosa of Wistar and Holtzman rats was isolated and characterized. This bacterium was gram negative, its cells were rod shaped with pointed ends, and its protoplasmic cylinder was entwined with periplasmic fibers. It was catalase and oxidase positive, rapidly hydrolyzed urea, and was susceptible to metronidazole and resistant to cephalothin and nalidixic acid. The new organism was microaerophilic and grew at 42°C, a feature that differentiates it from two other murine intestine colonizers,Helicobacter hepaticusandHelicobacter muridarum. On the basis of 16S rRNA sequence analysis data, the new organism was identified as aHelicobacterspecies that is most closely related toH. hepaticus. This bacterium is namedHelicobacter trogontum. The type strain is strain LRB 8581 (= ATCC 700114).
