对16株口腔共生的simonserella进行了16S rDNA测序，并用于评估simonserella菌株与奈瑟菌科其他成员的关系。在所有分析中，simonella菌株根据已确定的物种名称和从其分离出来的哺乳动物宿主进行分组。猫和狗的共生体形成了一个单系群。然而，simonella属的单一性既不能被支持也不能被拒绝；根据系统发育方法或分析中使用的特定序列，树中的深层节点是不稳定的。不稳定性可能归因于奈瑟氏菌或奈瑟科其他成员与锡蒙氏菌之间频繁的基因转移。
16S rDNA was sequenced from 16 strains of the oral commensal Simonsiella and was used to assess relationships between Simonsiella strains and other members of the Neisseriaceae. in all analyses, Simonsiella strains grouped according to established species designations and the mammalian hosts from which they were isolated. The commensals from cats and dogs formed a monophyletic group. The monophyly of the genus Simonsiella, however, could be neither supported nor rejected; deep nodes in the trees were unstable depending on the phylogenetic method or on the particular sequences used in the analysis. Instabilities may be attributable to frequent gene transfer between Neisseria or other members of the Neisseriaceae and Simonsiella.
