摘    要:于1998年7-9月,在发生贝类大规模死亡的山东工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--衣原体样原核生物和类立克次氏体。病理学研究表明,寄生原核生物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。

关 键 词:栉孔扇贝死亡  衣原体样  原核生物  类立克次氏体

Abstract:From July to Sept, 1998, the pathological chanes of the mass mortality of Chlamys farreri in Chandao and Yantal disincts of Shandong province were studied by light and electron nicroscopes. 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 caemsa positive. Ultrastructurally, CLO appeared to have three stages:initial bodies, intermediate bodies and elementary bodies; RLO undrwent typical pregranular and granular developmental stages with outer puffy trilaminar membranes. It is regardd as RLO and CLO that had caused the mass mortality of Chlamps farreri.
Keywords:Chlamys farreri Chlamydia-like Organisms Rickettsia-like Organisms
