| 摘要: |
| 于1998年7–9月，在发生贝类大规模死亡的山东省长岛县和烟台四十里湾养殖区，选取濒死的栉孔扇贝，通过组织病理分析和电镜观察，发现大量寄生原核生物—衣原体样原核生物（Chlamydia-like Organisms，CLO）和类立克次氏体（Rickettsia-like Organisms，RLO）。病理学研究表明，寄生原核生物（CLO和RLO）造成栉孔扇贝组织细胞严重病变，可能是引起栉孔扇贝大规模死亡的重要原因。 |

| Abstract: |
| From July to Sept., 1998, the pathological changes of the mass mortality of Chlamys farreri in Changdao and Yantai districts of Shandong province were studied by light and electron microscopes. Two parasitic organisms were discovered in Chlamys farreri. They are Chlamydia-like Organisms (CLO) and Rickettsia-like Organisms (RLO). Under the light microscope, the organisms parasitized in Chlamys farreri appeared as eosinophilic intracytoplasm inclusions, the inclusion was Gram-weigert negative and Giemsa positive. Ultrastructurally, CLO appeared to have three stages: initial bodies, intermediate bodies and elementary bodies; RLO underwent typical pregranular and granular developmental stages with outer puffy trilaminar membranes. It is regarded as RLO and CLO that had caused the mass mortality of Chlamys farreri. |
