摘要:
中华绒螯蟹 (以下简称河蟹)"颤抖病"是近几年来我国河蟹养殖区危害最大的病害之一,对取自江苏省淮阴地区的病蟹进行的组织和超微结构研究显示,在所有病蟹体内均发现大量寄生的类立克次体生物,而在取自未发病区域的健康河蟹体内没有发现类立克次体生物,类立克次体生物主要分布在河蟹的肌肉组织、结缔组织和血细胞内,它可以破坏河蟹肌细胞的肌纤维和肌原纤维,损害运动系统,这与河蟹的颤抖现象相吻合,因此作者推断它有可能是引发"颤抖病"的病原体.

Abstract:
The "Appendage Shaking Disease" (ASD) of Eriocheeir sinensis has been one of the most serious disease in the farmed freshwater crabs of China in the past five years.The ultrastructural study on the affected crabs sampled from Huaiyin district, Jiangsu Province indicated th at massive Richettsia-like organisms (RLO) had been found in all th e affected crabs.However, no RLO was found in healthy crabs sampled from East Taihu Lake, Jiangsu Province where there was no epidemic of ASD.The RLO that have mainly infected the periopod muscle organization and blood cell of crabs and amage th periopod muscle fiber of muscle cell and, hence, be harmful to the locomotion system of crabs.This was identical with the symptom of ASD.So we come to the conclusion that RLO is probably the pathogen of ASD.
Key words:  Eriocheeir sinensis  ultrast ructure  Appendage Shaking Disease  Richettsia-like organisms
