“对虾暴发性流行病防治及控制技术研究”,是由中国水产科学研究院黄海水产研究所承担的国家“八五”科技攻关项目。自1993年以来,该所科研人员在对虾暴发性流行病的病因病原研究(包括病原病理学研究和流行病学)、综合防病技术研究(包括生态控制防病研究、防治药物的筛选开发和病毒检疫诊断技术研究)方面,做了大量深入细致的工作,撰写了论文和研究报告43篇,完成了攻关合同规定的研究任务和主要经济技术指标,并通过了农业部组织的专家验收。 该课题分两个方面进行研究。经过近3年的科研攻关,在病原病因研究方面,确定了引起我国1993年以来养殖对虾暴发性流行病是一种新的杆状病毒引起的疾病,暂定名为“皮下及造血组织坏死杆状病毒”。解决了该病毒在提纯过程中囊膜降解的关键技术,获得了纯化病毒,弄清了其衣壳形态结构,DNA某些性质和多肽结构,掌握了患病对虾的典型病症、病理变化、致病机理和该病毒的主要传播途径。在病因——虾池环境——虾体之间的相互关系中,找出了发病的一些原因和条件,推动了国内同类
“Epidemic prevention and control of prawn epidemic disease and control technology”, by the Chinese Academy of Fishery Sciences Yellow Sea Fisheries Research Institute of the national “Eighth Five-Year” scientific and technological projects. Since 1993, the researchers in the etiology and pathogenesis of epidemic shrimp epidemic (including pathogenic pathology and epidemiology), integrated disease prevention technology research (including ecological control of disease prevention, prevention and treatment of drug screening and development and Virus quarantine diagnosis technology), a large number of in-depth and meticulous work has been done, and 43 papers and research reports have been drafted. The research tasks and major economic and technical indicators stipulated in the research contract have been completed and passed the acceptance by experts organized by the Ministry of Agriculture. The subject is studied in two aspects. After nearly 3 years of scientific research, in the etiology of the cause of the study, identified in our country since 1993 caused by shrimp epidemic epidemic is a new baculovirus-caused disease, tentatively named “subcutaneous and hematopoietic necrosis of the rod Like virus. ” The key technology of the virus degradation in the process of purification was solved. The purified virus was obtained, the morphological structure of the capsid, some properties of DNA and the structure of the polypeptide were clarified, and the typical pathological changes of prawn Pathogenesis and the main route of transmission of the virus. In the etiology - shrimp pond environment - the relationship between shrimp body, find out some of the causes and conditions of onset, promote similar domestic
