Iodamoeba is the last genus of obligately parasitic human protist whose phylogenetic position is unknown. Iodamoeba small subunit ribosomal DNA sequences were obtained using samples from three host species, and phylogenetic analyses convincingly placed Iodamoeba as a sister taxon to Endolimax. This clade in turn branches among free-living amoeboflagellates of the genus Mastigamoeba. Two Iodamoeba ribosomal lineages (RL1 and RL2) were detected whose sequences differ by 31%, each of which is found in both human and nonhuman hosts.
碘泡虫是最后一个尚未明确其系统发育位置的专性寄生人体原生动物属。通过对三个宿主物种的样本进行测序，得到了碘泡虫的小亚基核糖体 DNA 序列。系统发育分析令人信服地将碘泡虫置于内变形虫科的姐妹群中。这个分支在自由生活的类变形虫属 Mastigamoeba 中进一步分枝。检测到两个碘泡虫核糖体谱系（RL1 和 RL2），它们的序列差异为 31%，每个谱系都存在于人类和非人类宿主中。
