使用磷酸甘油酸激酶 (Pgk) 氨基酸序列重新检查了软体动物的系统发育位置。迄今为止未发表的丝状支原体亚种序列。分析中包括蕈状菌、猪肺炎支原体和柑橘螺原体。基于 Pgk 数据的系统发育树表明，厚壁菌门内的软体菌门是单系起源，而杆菌（厚壁菌门）和梭状芽孢杆菌（厚壁菌门）似乎是并系起源。除了聚集在厚壁菌门内的两个例外，即栖热袍菌属 (Thermotogae) 和梭杆菌属 (Fusobacteria)，比较分析表明，在低分类水平上，从 Pgk 蛋白和 16S rRNA 基因序列数据推断出的已解决的系统发育关系是一致的。
The phylogenetic position of the Mollicutes has been re-examined by using phosphoglycerate kinase (Pgk) amino acid sequences. Hitherto unpublished sequences from Mycoplasma mycoides, subsp. mycoides, Mycoplasma hyopneumoniae and Spiroplasma citri were included in the analysis. Phylogenetic trees based on Pgk data indicated a monophyletic origin for the Mollicutes within the Firmicutes, whereas Bacilli (Firmicutes) and Clostridia (Firmicutes) appeared to be paraphyletic. With two exceptions, i.e. Thermotoga (Thermotogae) and Fusobacterium (Fusobacteria), which clustered within the Firmicutes, comparative analyses show that at a low taxonomic level, the resolved phylogenetic relationships that were inferred from both the Pgk protein and 16S rRNA gene sequence data are congruent.
