The 16S rRNA sequences of Kingella indologenes, Cardiobacterium hominis, and Bacteroides nodosus were determined by direct RNA sequencing, using a modified Sanger method. Sequence comparisons indicated that these three species represent a novel family in the gamma division of Proteobacteria. On the basis of these data, K. indologenes and B. nodosus cannot retain their current generic status as they are not closely related to other members of their assigned genera. Therefore, we propose transfer of K. indologenes to the new genus Suttonella as Suttonella indologenes and transfer of B. nodosus to the new genus Dichelobacter as Dichelobacter nodosus and assign the genera Cardiobacterium, Suttonella, and Dichelobacter to a new family, Cardiobacteriaceae, in the gamma division of Proteobacteria.
采用改良的桑格法，通过直接RNA测序确定了产吲哚金氏菌、人心杆菌和结节拟杆菌的16S rRNA序列。序列比较表明，这三个物种代表了变形菌纲γ亚纲中的一个新科。基于这些数据，产吲哚金氏菌和结节拟杆菌不能保留其当前的属地位，因为它们与所属属的其他成员关系不密切。因此，我们建议将产吲哚金氏菌转移到新属萨顿菌属，命名为吲哚萨顿菌，将结节拟杆菌转移到新属双歧杆菌属，命名为结节双歧杆菌，并将人心杆菌属、萨顿菌属和双歧杆菌属归入变形菌纲γ亚纲中的一个新科——心杆菌科。
