皱纹盘鲍一种球形病毒的感染及其发生

在发病的皱纹盘鲍（HaliotisdiscushannaiIno）幼鲍的足、内脏团、外套膜的血细胞质内，发现一种直径为90～140um的球形病毒粒子，带双层囊膜，无包涵体。负染病毒粒子与超薄切片大小形态相同。用被病毒感染的患病幼鲍感染健康鲍获同样症状，死亡率为50％。并于人工感染死亡鲍鱼体内观察到同样病毒。

Infection of Spherical Viruses from Haliotis discus hannai Ino

The spherical virion with the size of 90~ 140 nm in diameter was detected in blood cell ma-trix of the feet, mantle and internal organization of diseased abalone. The virion was surrounded by dual unit membrane, no inclusion body. The morphology and size of virion in negative staining were the same as the observation in ultrathin sections. Identical symptom appeared in artificial in-fection experiment. The rate of death was 50%. Identical virion was observed in the dead abalone
