【摘要】 共研究了9种动物病毒在宿主细胞内的繁殖特点。一、无囊膜的病毒粒子在宿主细胞内常呈晶格排列。经常可观察到A型口蹄疫病毒在胞质内呈晶格排列,但O型口蹄疫病毒却观察不到晶格排列。二、观察到猪传染性水泡病病毒的特异装配形式。三、病毒繁殖时,诸如线粒体、粗面内质网与溶酶体等重要细胞器超微结构的变化,似与病毒的分类地位无关。四、大多数RNA病毒繁殖时,宿主细胞核的超微结构变化明显,而DNA病毒繁殖时,宿主细胞核早期超微结构的变化不显著。五、动物病毒感染时能引起宿主细胞内出现一些新的结构,除毒浆结构(Viroplast)外,还有层板膜结构,微管与微纤维。

【Abstract】 The morphogeneses of 9 spp. animal viruses in host cells in culture were studied, and the results were summarized as follow:1. Virions without envelopes usually arranged in crystalline pattern in hos cells. FMD(A) virions arranged in the same pattern, but FMD (O) virions did not arranged in that way.2. The assembled structure of SVDV (Swine vesicle disease virus) was observed. Its pattern and site of formation in the vesiculae of endoplasmic reticulum were noted.3. When viruses multiplied in the host cells, changes of important organelles such as mitochondria, rough endoplasmic reticulum and lysosomes were observed. It seemed that there was no direct relation between these structural changes and the taxonomic position of the viruses.4. The ultrastructural changes in the nucleus of RNA virus-infected cells were still more significant than those taken place in DNA virus-infected cells.5. Multiplication of the animal viruses stimulated the host cells to produce some new structures such as viroplast, microtubules, fibres and myelinoid bodies.
