测定了近50种支原体及其壁亲的小亚基rRNA序列，为系统分析这些生物的系统发育奠定了基础。共识别出五组支原体(暂定名称)：人支原体组(包括人支原体、脂支原体、肺支原体和神经溶解支原体)，肺炎支原体组(包括肺炎支原体和鼠支原体)，螺旋体组(包括支原体支原体、柑橘螺旋体和APIs)，厌氧浆组(包括厌氧胞浆和非胞浆)，以及已知只含有分离的Asteroleanobobium的一组。除了这五组支原体外，第六组不同名称的革兰氏阳性有壁生物(包括乳杆菌、梭状芽胞杆菌和其他生物)也被包括在整个系统发育单位中。在这六个初级组中的每一个组中，亚组都很容易识别和定义。虽然通过rRNA比对确定的系统发育单位很难仅基于相互排斥的表型特征来识别，但其中一些表型单位的表型合理性可以在后验给予证明。
Small-subunit rRNA sequences were determined for almost 50 species of mycoplasmas and their walled relatives, providing the basis for a phylogenetic systematic analysis of these organisms. Five groups of mycoplasmas per se were recognized (provisional names are given): the hominis group (which included species such as Mycoplasma hominis, Mycoplasma lipophilum, Mycoplasma pulmonis, and Mycoplasma neurolyticum), the pneumoniae group (which included species such as Mycoplasma pneumoniae and Mycoplasma muris), the spiroplasma group (which included species such as Mycoplasma mycoides, Spiroplasma citri, and Spiroplasma apis), the anaeroplasma group (which encompassed the anaeroplasmas and acholeplasmas), and a group known to contain only the isolated species Asteroleplasma anaerobium. In addition to these five mycoplasma groups, a sixth group of variously named gram-positive, walled organisms (which included lactobacilli, clostridia, and other organisms) was also included in the overall phylogenetic unit. In each of these six primary groups, subgroups were readily recognized and defined. Although the phylogenetic units identified by rRNA comparisons are difficult to recognize on the basis of mutually exclusive phenotypic characters alone, phenotypic justification can be given a posteriori for a number of them.
