A spiral-shaped bacterium with bipolar, single, nonsheathed flagella was isolated from the feces of Syrian hamsters. The bacterium grew as a thin spreading film at 37 degrees C under microaerobic conditions, did not hydrolyze urea, was positive for catalase and alkaline phosphatase, reduced nitrate to nitrite, did not hydrolyze hippurate, and was sensitive to nalidixic acid but resistant to cephalothin. Sequence analysis of the 16S rRNA gene and biochemical and phenotypic criteria indicate that the novel bacterium is a helicobacter. The novel bacterium is most closely related to the recently described mouse enteric helicobacter, Helicobacter rodentium. This is the first urease-negative Helicobacter species with nonsheathed flagella isolated from feces of asymptomatic Syrian hamsters. We propose to name this novel helicobacter Helicobacter mesocricetorum. The type strain is MU 97-1514 (GenBank accession number AF072471).
从叙利亚仓鼠粪便中分离出一种具有双极、单根、无鞘鞭毛的螺旋形细菌。该细菌在微需氧条件下于37℃以薄扩散膜形式生长，不水解尿素，过氧化氢酶和碱性磷酸酶呈阳性，将硝酸盐还原为亚硝酸盐，不水解马尿酸盐，对萘啶酸敏感但对头孢噻吩耐药。16S rRNA基因序列分析以及生化和表型标准表明，该新型细菌是一种螺杆菌。该新型细菌与最近描述的小鼠肠道螺杆菌——啮齿类螺杆菌关系最为密切。这是从无症状叙利亚仓鼠粪便中分离出的首例无鞘鞭毛且脲酶阴性的螺杆菌物种。我们提议将这种新型螺杆菌命名为中仓鼠螺杆菌。模式菌株为MU 97 - 1514（GenBank登录号AF072471）。
