Four strains of an unknown coryneform bacterium were isolated in pure culture from females with urinary tract infections. Strong urease activity and the ability to slowly ferment maltose but not glucose were the most significant phenotypic features of this catalase-positive, nonmotile, nonlipophilic, rod-shaped bacterium which served to distinguish it from all other presently defined coryneform bacteria. Chemotaxonomic investigations demonstrated that the unknown bacterium belonged to the genus Corynebacterium. Comparative 16S rRNA gene sequence analysis revealed that the isolates were genealogically identical and represented a new subline within the genus Corynebacterium, for which the designation Corynebacterium riegelii sp. nov. is proposed. The type strain of Corynebacterium riegelii is CCUG 38180 (DSM 44326, CIP 105310).
从患有尿路感染的女性中分离出四株未知的棒状杆菌,进行纯培养。这种过氧化氢酶阳性、无运动性、不嗜脂、杆状细菌的最显著表型特征是具有强脲酶活性以及缓慢发酵麦芽糖但不发酵葡萄糖的能力,这使其与目前所有已定义的棒状杆菌区分开来。化学分类学研究表明,该未知细菌属于棒状杆菌属。比较16S rRNA基因序列分析显示,这些分离株在谱系上相同,代表棒状杆菌属内的一个新亚系,为此提议命名为里氏棒状杆菌(Corynebacterium riegelii sp. nov.)。里氏棒状杆菌的模式菌株是CCUG 38180(DSM 44326,CIP 105310)。
