摘　　要：对患颤抖病的中华绒螯蟹 (Eriocheirsinensis)神经和肌肉组织进行光镜和电镜观察 ,结果显示类立克次体广泛存在于胸神经节中的神经胶质细胞、结缔组织以及细胞间隙中。在神经细胞与步足肌肉细胞连接处 ,即运动终板部位有大量类立克次体侵染 ,并且侵染方式与在胸神经节中一样 ,均以聚集成团的形式存在。胸神经节是支配步足的神经丛 ,而颤抖病是以步足颤抖为主要病症的疾病。类立克次体大量侵染胸神经节和运动终板部位 ,表明该微生物与病蟹步足颤抖的病症有密切关系 ,进一步证明类立克次体是颤抖病的致病微生物。An optical and transmission electron microscope study on nerve tissue of thoracic ganglion and muscles in the crab, Eriocheir sinensis which suffering from tremor disease,indicated that rickettsia like organisms (RLO) infested in glial cells,connective tissue and intercellular space.In the connection between nerve and muscle fibers-motor end plate,there were also a lot of RLOs in groups,just like the way in the nerve tissue.Thoracic ganglion is a nerve plexus controlling the moving of periopods.The fact that RLO infested this tissue and the motor end plate verifies that RLO closely relates to the tremor disease,which main disorder is paroxysmal tremor of the periopods.This is firmly confirmed that RLO is a pathogenic parasite of the tremor disease.
