摘要
1994~1996年对大连地区患“裂壳病”的养殖鲍苗种进行光镜和电镜观察。通过观察和人工感染实验证实,该病的病原为一种大小90~140nm的球状病毒,该病毒主要侵染血细胞。病症为鲍壳薄,壳缘外翻,壳孔相互串连,摄食力降低,生长缓慢,逐渐死亡。并观察了外套膜、足、鳃、肝脏、嗉囔等主要器官的组织病理变化。
This paper reported the observation about “crack shell disesae” of cultural abalone baby by microscope and electronic microscope. The symptoms are as follows: the shell is thin,the edge is turndowning, the hole is linking, the absorbing abilities decrease, and the growing rate is much low. The pathogen is a kind of spherical virion which was determined by observation and artificially infected experiment.The virion mainly invaded the blood cells. This studies also observed the histopathological changes of mantle,feet,gill,liver and crop and pointed out the infection like change appeared in epidermis and connective tissue cells of main organ and the ultrastructure changes is the mitochondrion expansion, the ridge disappearing, and the endoplasm disintegrating. The necrosis of digestive, respire and move organs accelerated the death of the abalone. The infecting channel is horizontal. Meanwhile the pathogenic characters were discussed.
