Determination of the 16S rRNA gene sequence of Caulobacter subvibrioides ATCC 15264T (T = type strain) confirmed that this species is a member of the alpha subclass of the Proteobacteria and showed that it is phylogenetically most closely related to the Caulobacter group comprising the species Caulobacter bacteroides, Caulobacter crescentus, and Brevundimonas (Pseudomonas) diminuta, for which 16S rRNA sequences of the type strains are currently available. The closest known relative of strain ATCC 15264T among these species is B. diminuta (level of direct pairwise sequence similarity, 95%). On the basis of its previously determined 16S rRNA sequence (accession number M83797), C. subvibrioides is most closely related to Sphingomonas adhaesiva in the alpha-4 subgroup (level of similarity, 97.7%). Analysis of the hydroxy fatty acids of C. subvibrioides ATCC 15264T showed that the 2-hydroxymyristic acid which is characteristic of the genus Sphingomonas was absent.
对浅弧柄杆菌ATCC 15264T（T = 模式菌株）的16S rRNA基因序列测定证实，该物种是变形菌门α亚类的成员，并表明它在系统发育上与包括拟杆菌柄杆菌、新月柄杆菌和缺陷短波单胞菌（假单胞菌属）的柄杆菌类群关系最为密切，目前已有这些模式菌株的16S rRNA序列。在这些物种中，菌株ATCC 15264T最接近的已知亲缘种是缺陷短波单胞菌（直接成对序列相似性水平为95%）。根据其先前确定的16S rRNA序列（登录号M83797），浅弧柄杆菌与α-4亚群中的粘附鞘氨醇单胞菌关系最为密切（相似性水平为97.7%）。对浅弧柄杆菌ATCC 15264T的羟基脂肪酸分析表明，鞘氨醇单胞菌属特有的2-羟基肉豆蔻酸不存在。
