The name Yokenella gen. nov. is proposed for a group of organisms in the family Enterobacteriaceae isolated from clinical sources and insects. Yokenella is a gram-negative, oxidase-negative, fermentative, motile rod possessing the characteristics of the family Enterobacteriaceae and the guanine plus cytosine contents of the DNA range from 58.0 to 59.3 mol%. Biochemical characteristics of this group and DNA hybridization studies indicate that the 11 strains studied here comprise a separate species which should be best placed in a new genus. This single DNA hybridization group is named Yokenella regensburgei sp. nov. The type strain of Y. regensburgei is NIH 725-83 (JCM 2403).
提议将“约肯氏菌属（Yokenella gen. nov.）”命名用于从临床样本和昆虫中分离出的肠杆菌科中的一组微生物。约肯氏菌是革兰氏阴性、氧化酶阴性、发酵型、具运动性的杆菌，具有肠杆菌科的特征，其DNA的鸟嘌呤加胞嘧啶含量范围为58.0至59.3摩尔%。该组的生化特征及DNA杂交研究表明，此处研究的11株菌株构成一个独立的种，最好置于一个新属中。这个单一的DNA杂交组被命名为雷根斯堡约肯氏菌（Yokenella regensburgei sp. nov.）。雷根斯堡约肯氏菌的模式菌株是NIH 725 - 83（日本模式培养物集存中心2403）。
