利用电镜技术对患病濒死皱纹盘鲍 (H aliotis Discus hanna Ino)进行病原体检测和病理观察 ,在肠上皮组织中发现大量立克次体。研究表明 ,皱纹盘鲍肠上皮细胞中的立克次体分为增殖型立克次体和静止型立克次体 2种类型。立克次体以皱纹盘鲍肠上皮细胞为感染的靶细胞 ,造成细胞微绒毛全部或部分破坏 ,细胞功能丧失 ,是造成养殖皱纹盘鲍病害发生和死亡的主要病原体。
Pathological examination and pathological examination of diseased Haliotis Discus hanna Ino were carried out by electron microscopy. A large number of rickettsial plants were found in the intestinal epithelium. Studies have shown that rickettsia abacus epithelial cells are divided into two types of proliferative rickettsial and resting rickettsia. Rickettsia to abalone Haliotis discus hannai infection of target cells, resulting in all or part of cell microvilli damage, loss of cell function, is caused by the cultivation of Haliotis discus hannai disease pathogenesis and death of the main pathogens.
