引起九孔鲍大量死亡的一种球状病毒

A sphereovirus resulted in mass mortality of Haliotis diversicolor aquatilis

对 1999年初春福建省东山县工厂化养殖九孔鲍中发生的流行性死亡 ,开展了九孔鲍的病理学研究 ,电镜下发现病鲍的肝脏细胞质中有大量具被膜 2 0面体、大小约为 10 0nm的病毒粒子。通过感染实验 ,推断该病毒是造成此次九孔鲍大量死亡的病原体 ;由于肝脏细胞的大量病变和坏死引起九孔鲍的大量死亡。

Mass mortality of abalone Haliotis diversicolor aquatilis, occurred at abalone farms of Dongshan Prefecture, Fujian Province during the spring of 1999 and Since then pathological study was performed. Electron micrography revealed mass enveloped, about 100nm in diameter, hexagonal particles in the cytoplasm of liver of diseased abalone. Artificial infected experement revealed that the virus is the lethal pathogen of mass mortality, and histopathological changes and necrosis of the liver cell were the reshan of death.A further study on specib clasifieation of virus will be needed.
