| 摘 要： | １９９４－１９９５年山东文登市高岛盐厂对虾育苗池和养虾池，随机和定点采集中国对虾的卵，无节幼体，蚤状幼体，糠虾幼体，仔虾及幼虾，成虾样品，利用透射电子显微镜对其进行病毒的检测。结果表明，卵细胞中含有大量的卵黄，没有明显的细胞分化，卵细胞质中有球形病毒感染；无节幼体的肝胰腺和上皮细胞的分化程度较低，有大量球形病毒分布；糠虾幼体已有明显的肝胰腺和上皮细胞的分化，肝胰腺上皮细胞的胞质中发现有球形病毒包涵

| Abstract: | In 1994 and 1995, eggs and larvae of Penaeus chinensis were collected from prawn seedling ponds in Gaodao, Wendeng, Shandong Province. To determine the virus infection, samples of different stages of P. chinensis larvae and eggs were observed by a bosmission electron dricroscope. The results show that there is a lot of yolk in the egg, but no remarked cell differentiation, and there is spheroid virus infection in the cytoplasm of eggs. There is slight differentiation in the hepato-pancreatic and epidermal cells, with a lot of spheroid virus in them.There are distingnishable differentiation in the hepato-panreatic cells and a lot of spheriod virus and its inclusion body in the epidermal cell cytoplasm. Spheroid virus infection occurs in the hepato-pancreatic cells of post lareae. In the juvenile and adult prawns, the spheroid virus mainly infects the hepato-pancreatic tissue, mid-gut muscles etc. The spheroid virus encysts are scattered in the cytoplasm with a diameter of about 70-100nm. The virus has a complete capsid, with a layer of rough membrane outside the capsid. It has also an inclusion body. That virus was observed in eggs strongly suggests the possibility of vertical transmission by eggs. |
