The phylogeny of kinetoplastid flagellates was investigated by determining the sequences of the small-subunit (18S) rRNA from Bodo designis, Bodo saltans K, Bodo saltans P, Bodo sorokini, Bodo sp. (cf. uncinatus), Cruzella marina, Cryptobia helicis, Dimastigella mimosa and Parabodo nitrophilus and analysing these data together with several previously obtained sequences. The root of the kinetoplastid tree was tentatively determined to be attached to the branch of B. designis and/or Cruzella marina. Within this topology, the suborder Trypanosomatina appears as a late-emerging monophyletic group, while the suborder Bodonina is paraphyletic. Within the bodonid subtree, the branches of parasitic organisms were intermingled with free-living ones, implying multiple transitions to parasitism. The tree indicates that the genera Cryptobia and Bodo are artificial taxa. In addition, the separation of the fish cryptobias and Trypanoplasma borreli as different genera was not supported.
通过测定来自设计波豆虫、盐生波豆虫K、盐生波豆虫P、索氏波豆虫、波豆虫属（类似钩状波豆虫）、滨海克鲁兹虫、螺旋隐鞭虫、含羞双鞭虫和嗜硝副波豆虫的小亚基（18S）rRNA序列，并将这些数据与之前获得的一些序列一起进行分析，对动基体鞭毛虫的系统发育进行了研究。动基体树的根初步确定附着在设计波豆虫和/或滨海克鲁兹虫的分支上。在这种拓扑结构中，锥虫亚目表现为一个较晚出现的单系类群，而波豆亚目是并系的。在波豆虫亚树中，寄生生物的分支与自由生活生物的分支相互交织，这意味着向寄生生活的多次转变。该树表明隐鞭虫属和波豆虫属是人为分类单元。此外，鱼类隐鞭虫和博氏锥虫被划分为不同属的分类方式未得到支持。
