海洋贝类细胞内寄生原核生物研究进展

Intracellular prokaryote in marine shellfish-A review

在海洋贝类中寄生的细胞内寄生原核生物主要包括立克次体(Rickettsia)和衣原体(Chlamydia),通常寄生于宿主的鳃和消化腺上皮组织细胞的细胞质内,一般形成嗜碱性包涵体,可对宿主细胞造成一定的损伤,但在一般情况下不会引起宿主的系统病理变化,也不会导致死亡。本文对该方面国内外研究的历史、进展和现状进行了系统的总结,对海洋贝类原核生物感染的宿主范围、危害、检测方法及存在的问题进行了阐述,对该领域今后的发展方向进行了展望。

The intracellular prokaryotes infecting marine shellfish mainly include Rikettsia and Chlamydia, which usually live in the cytoplasm of epithelial cell of gill and digestive gland and form basophilic intracytoplasm inclusions. The hosts included oyster, clam, mussel, scallop and abalone. In general opinion, intracellular prokaryotes living in marine shellfish is a normal phenomenon and is harmful to the host. But in fact, only under certain conditions, the infection can bring about some damages to target cells and may lead to systematic pathogenic changes and death of host. The present paper made a review on research history, proceedings and previewed of the further study in the area so to provide some evidences and ideas for the researchers who are engaged in disease control and prevention research on shellfish.
