摘要
本试验应用光镜、电镜技术,对人工感染兔出血症病毒(RHDV)的成年兔、30～40日龄幼兔以及自然感染死亡病例的各种组织器官进行了病理形态学动态观察。结果表明,成年兔对本病毒易感,表现出与自然病例相似的典型变化,而30～40日龄幼兔则易感性低,缺乏特征病变。在患兔的肝细胞中观察到病毒粒子呈散在或聚集成包涵体样存在于核内及胞浆中,佐证本病毒为DNA病毒。
The dynamic changes of rabbits haemorrhagic disease(RHD)'s pathomorphology in experimentally infected adult rabbits, 30～40day—old rabbits and naturally infected rabbits were studied by light and electronmicroscopy. The result showed that adult rabbits had strong sensitive toRHDV. It' s pathological chan ges were the same as naturally infected rabbits. 30～40 day-old rabbits had low sensitive and lack of typical RHD changes. The inclusions and diffuseness of RHDV in the nuclei and cytoplasm for infected liver cell were detected by clectronmicr oscopy. The RHDV is probably a DNA virus.
