The phylogenetic relationships between the mycoplasmas and bacteria have been established from a comparative analysis of their 16S rRNA oligonucleotide catalogs. The genera Mycoplasma, Spiroplasma, and Acholeplasma arose by degenerative evolution, as a deep branch of the subline of clostridial ancestry that led to Bacillus and Lactobacillus. Thermoplasma has no specific relationship to the other mycoplasmas; it belongs with the archaebacteria.
通过对支原体和细菌的16S rRNA寡核苷酸序列目录进行比较分析,确定了它们之间的系统发育关系。支原体属、螺原体属和无胆甾原体属是通过退化进化产生的,是梭菌谱系中导致芽孢杆菌属和乳杆菌属的一个深分支。嗜热菌与其他支原体没有特定关系;它属于古细菌。
