Comparative analysis of 16S rRNA sequences shows that the family Spirosomaceae belongs within the eubacterial phylum defined by the flavobacteria and bacteriodes. Its constituent genera, Spirosoma, Flectobacillus, and Runella form a monophyletic grouping therein. The phylogenetic assignment is based not only upon evolutionary distance analysis, but also upon sequence signatures and higher order structural synapomorphies in 16S rRNA. Another genus peripherally associated with the Spirosomaceae, Ancylobacter ("Microcyclus"), does not cluster with the flavobacteria and their relatives, but rather belongs to the alpha subdivision of the purple bacteria.
对16S rRNA序列的比较分析表明，螺菌科属于由黄杆菌和拟杆菌定义的真细菌门。其组成属，即螺菌属、弯曲杆菌属和柄杆菌属在其中形成一个单系类群。系统发育归属不仅基于进化距离分析，还基于16S rRNA中的序列特征和高阶结构共衍征。另一个与螺菌科外围相关的属，即弯杆菌属（“微环菌属”），并不与黄杆菌及其亲缘类群聚类，而是属于紫色细菌的α亚群。
