On the basis of 16S-23S ribosomal DNA analyses, the whitefly Bemisia tabaci (Sternorrhyncha, Aleyrodidae) and the eriococcid Eriococcus spurius (Sternorrhyncha, Eriococcidae) were each found to harbor novel related chlamydial species within the family Simkaniaceae. The generic designation Fritscheagen. nov. is proposed to accommodate the two species, F. bemisiaesp. nov. and F. eriococci sp. nov. The finding of chlamydial 16S-23S ribosomal DNA in B. tabaci is consistent with a previous electron microscopy study which found that bacteriocytes of this species contain structures that we consider to resemble the elementary and reticulate bodies of chlamydia (Costa HS, Westcot DM, Ullman DE, Rosell R, Brown JK, Johnson MW. Protoplasma 189:194-202, 1995). The cloning and sequencing of a 16.6 kilobase DNA fragment from F. bemisiae indicated that it contains six genes encoding for proteins similar to those found in other species of chlamydia. These results extend the range of organisms that harbor chlamydia.
基于16S - 23S核糖体DNA分析，发现烟粉虱（半翅目，粉虱科）和刺绵蚧（半翅目，绵蚧科）各自携带着西姆卡尼亚科内新的相关衣原体物种。提议使用新属名Fritscheagen. nov. 来容纳这两个物种，即新种烟粉虱衣原体（F. bemisiaesp. nov.）和新种刺绵蚧衣原体（F. eriococci sp. nov.）。在烟粉虱中发现衣原体16S - 23S核糖体DNA，这与之前的一项电子显微镜研究结果一致，该研究发现该物种的含菌细胞含有我们认为类似于衣原体原体和网状体的结构（科斯塔HS、韦斯科特DM、厄尔曼DE、罗塞尔R、布朗JK、约翰逊MW。原生质体189:194 - 202，1995）。对来自烟粉虱衣原体的一个16.6千碱基DNA片段进行克隆和测序表明，它包含六个编码与其他衣原体物种中发现的蛋白质相似的蛋白质的基因。这些结果扩展了携带衣原体的生物范围。
