从实验室豌豆蚜虫Acyrthosiphon pisum菌株中，我们发现了一种以前未知的兼性内共生细菌。基于16S核糖体DNA的分子系统发育分析表明，该细菌是螺原体属的成员。螺原体有机体表现出稳定的垂直传播，通过连续几代的主机。将感染昆虫的血淋巴注射到未感染的昆虫中，在受体中建立了稳定的感染。螺原体共生体对宿主的生长、繁殖和寿命表现出负效应，特别是在老年人中。对58株A.从日本中部的自然群体中建立的豌豆，4个菌株具有螺原体生物体。
From a laboratory strain of the pea aphid, Acyrthosiphon pisum, we discovered a previously unknown facultative endosymbiotic bacterium. Molecular phylogenetic analysis based on 16S ribosomal DNA revealed that the bacterium is a member of the genus Spiroplasma. The Spiroplasma organism showed stable vertical transmission through successive generations of the host. Injection of hemolymph from infected insects into uninfected insects established a stable infection in the recipients. The Spiroplasma symbiont exhibited negative elects on growth, reproduction, and longevity of the host, particularly in older adults. Of 58 clonal strains of A. pisum established from natural populations in central Japan, 4 strains possessed the Spiroplasma organism.
