沃尔巴克氏体是一种细胞质变形菌，可诱导其节肢动物宿主的生殖行为发生严重改变。虽然沃尔巴克氏体在昆虫和陆生等足类动物中很常见，但在其他节肢动物群体中很少发现。通过对Wolbachia 16S rDNA的PCR扩增和测序，首次在水生甲壳纲介形虫中发现了Wolbachia 16S rDNA。讨论了这一发现的意义以及沃尔巴克氏体与介形虫生殖生活史特征（孤雌生殖和性别比例扭曲）之间的可能联系。
Wolbachia are cytoplasmic proteobacteria which induce severe modifications in the reproductive behaviour of their arthropod hosts. Although common in insects and terrestrial isopods, Wolbachia have seldom been found in other arthropod groups. Based on PCR amplification and DNA sequencing of Wolbachia 16S rDNA we report the first record of these endosymbiont bacteria in ostracods (Ostracoda), an exclusively aquatic crustacean group. The implications of this finding and the likely links between Wolbachia and ostracod reproductive life-history traits (parthenogenesis and sex-ratio distortion) are discussed.
