尽管细胞形态和细胞大小不同,但有些支原体显示出几种一致和独特的结构特征:瓶状或棒状细胞形态和或多或少明确的末端结构。具有这些特征的微生物可在肺炎支原体、M. genitalium、M. pulmonis,M.鸡败血症M. alvi,M. sualvi和支原体163 K.某些瓶状支原体的超微结构特征是表面绒毛和细胞骨架。除了M。alvi和M.对于缺乏详细研究的Sualvi,瓶形支原体与其他支原体的不同之处在于其滑动运动性和粘附性。所有的瓶形支原体发酵葡萄糖,但在其他生化性质的研究和鸟嘌呤+胞嘧啶的比例有差异。问题仍然是烧瓶形状,粘附性和运动性是否与致病性相关,因为具有这些特性的三种支原体是已确定的病原体。目前还没有关于其余四个物种的致病性的数据,但几项标准表明,其中至少有两个物种可能在疾病中起致病作用。
In spite of the variations in cell form and cell size, some mycoplasmas show several consistent and peculiar structural features: a flask- or club-shaped cell form and a more or less defined terminal structure. Organisms with these features can be observed within the species Mycoplasma pneumoniae, M. genitalium, M. pulmonis, M. gallisepticum, M. alvi, M. sualvi and Mycoplasma sp. strain 163 K. Ultrastructural peculiarities of some flask-shaped mycoplasmas are a surface nap and a cytoskeleton. With the exception of M. alvi and M. sualvi, for which detailed investigations are lacking, the flask-shaped mycoplasmas differ from the other mycoplasmas by their gliding motility and adherence properties. All of the flask-shaped mycoplasmas ferment glucose, but there are differences in the other biochemical properties investigated and in the guanine + cytosine ratio. The question remains whether the flask shape, the adherence and the motility are associated with pathogenicity, since three mycoplasmas with these properties are established pathogens. No data are available at present on the pathogenicity of the remaining four species, but several criteria suggest that at least two of them may have an etiological role in disease.
