通过人工感染实验,在感染三角帆蚌瘟病病料组织后第3、5、7、9、11 d,运用光学显微镜和电子显微镜分别观察了三角帆蚌(Hyriopsis cumingii)主要消化器官的病理变化特征.结果表明,三角帆蚌瘟病病毒(H.cumingii Plague Virus,HcPV)严重破坏了三角帆蚌消化器官的结构.主要消化腺肝损伤最为严重:光镜下,攻毒7 d内腺管肿大,管腔缩小,7 d后腺管细胞空泡化并形成多核体;电镜下,线粒体、内质网等细胞器结构破坏,病毒粒子增殖速度快.消化道的病理变化主要表现为胃、肠结构的破坏,胃肠基本结构及感染病毒后的病理变化相似:光镜下,攻毒7 d内胃肠结构变化不大,7 d后柱状细胞肿大,纤毛脱落,并伴有上皮细胞的脱...

The pathological changes of digestive organs were observed by optical microscopy and electron microscopy at the 3rd, 5th, 7th, 9th, and llth day after artificial infection of Hyriopsis cumingii with the pathological tissue liquid. The results showed that the H. cumingii Plague virus damaged the structure of the digestive organs. The liver was most seriously damaged. This digestive gland was swelling and its lumen was smaller at the 7th day of infection, and after that vacuolation and coenocytes were observed. Under electron microscope, the organelles such as mitochondria and endoplasmic reticu...
