The structure of the omega-particle-bacteria, growing in the micronucleus of Paramecium caudatum (Ciliata, Protozoa), was studied by electrom microscopy in the course of their life cycle. The cytoplasm of the spindle-shaped vegetative cells contains a large number of dense particles and transparent regions comprising the fibrillar material. Such cells, via several intermediate stages, are transformed into elongated twisted cells that are regarded as spores. The spore consists of two parts: homogeneous, and that containing the membrane system and rounded light bodies. The membranes are often double and connected with the fibrils. The cell wall is constructed, during all stages, of the outer membrane layer and the inner electron-dense layer.
在尾草履虫（纤毛虫纲，原生动物）微核中生长的ω-粒子细菌的结构，在其生命周期过程中通过电子显微镜进行了研究。纺锤形营养细胞的细胞质包含大量致密颗粒和由纤维状物质组成的透明区域。这样的细胞经过几个中间阶段转化为细长扭曲的细胞，被视为孢子。孢子由两部分组成：均匀的部分，以及包含膜系统和圆形浅色体的部分。膜通常是双层的，并与纤维相连。在所有阶段，细胞壁都由外膜层和内部电子致密层构成。
