草鱼出血房是由呼肠孤病毒感染所致的急性传染病,由于病鱼小血管受损引起全身性出血,并造成内脏器官和体壁肌肉组织局灶性病变。电镜观察表明病变细胞内各种细胞器的数量较正常细胞显著减少,形态结构也遭损坏。质膜的三层结构模糊不清,及至解体消失。与机体代谢密切相关的粗面内质网、滑面内质网、线粒体和高尔基复合体的数量减少及结构受损,使蛋白质、糖类和脂质合成及分解等一系列细胞代谢活动不能正常进行,加速了病鱼死亡。 Grass carp hemorrhage room is an acute infectious disease caused by reovirus infection, systemic blood loss due to impaired small blood vessels and cause focal lesions of visceral organs and body wall muscle tissue. Electron microscopy showed that the number of various organelles in diseased cells was significantly reduced compared with normal cells, and the morphological structure was also damaged. The three-layer structure of the plasma membrane is unclear, until it disappears. A series of cellular metabolic activities that are closely related to the metabolism of the body such as the rough endoplasmic reticulum, the smooth endoplasmic reticulum, the mitochondria and the Golgi complex, and the structure are impaired, resulting in the synthesis and decomposition of proteins, carbohydrates and lipids To accelerate the death of diseased fish.
