轮纹夜蛾是常见害虫蟑螂兼性共生的肠道寄主。其细胞大致呈球形，顶端有约50根鞭毛。有争议的是，基于对痰或支气管肺泡灌洗液中类似形状细胞的光镜观察，它与人类呼吸道感染有关。在此，我们测定了从蟑螂中分离到的 blattarum及其唯一的同源物Lopomonas striata的18SRRNA基因的序列。两种在一个完全支持的分支中分枝，具有毛状突起，与先前对L. striata的研究一致，但与归因于L. blattarum的人类样本的序列不一致。
Lophomonas blattarumis a facultative commensal gut dweller of common pest cockroaches. Its cells are roughly spherical in shape with an apical tuft of ~50 flagella. Controversially, it has been implicated in human respiratory infections based on light microscopic observations of similarly shaped cells in sputum or bronchoalveolar lavage fluid. Here, we have sequenced the 18S rRNA gene ofL. blattarumand its sole congener,Lophomonas striata, isolated from cockroaches. Both species branch in a fully supported clade with Trichonymphida, consistent with a previous study ofL. striata, but not consistent with sequences from human samples attributed toL. blattarum.
