Sequence analysis showed that the size of 16S rRNA gene was in 1235 bp, and lacking several regions which regarded as eukaryotic sequence, was more similar with prokaryotes than eukaryotes in sequence structural feature; it could be implied that the microsporidia had split from ancient eukaryotes very early in time on the phylogenetic tree.

序列分析表明，16SrRNA基因大小为1235bp，缺乏多个被认为是真核生物序列的区域，序列结构特征更多地类似于原核生物的，在进化上，推测微孢子虫在很早以前与原始真核生物产生分歧；分子进化分析发现，同属的微孢子虫可以处于系统进化树不同的分枝。
