This paper is a .review of literature on duck plague. In a comprehensive manner, it gives an account of the historical progress, ever since the discovery of the disease in 1923, of the studies on its causative agent ( a herpesvirus ) ' and other accomplishments by numerus scientists in different countries in. various periods of time, with special emphasis oh the contributions of Chinese research workers. In this review, there are two main portions, the first of which being descriptions of the properties of the causal agent and the second an account of the research work on vaccines preparation and the use put to these vaccines. In the first portion it includes the portal of entry and its distribution in the duck body, morphological characteristics, chemical composition, replication, cultivation, resistence, virulence, pathogenicity, antigenic structure, immunogenic, properties and variability of the virus. In the second portion it embodies the research accomplishments on inactivated vaccines and live -virus vaccines, as a result of their adoptability the outbreak of duck plague in this country was substantially kept under control.

本文是一篇文献综述,全面地叙述自从1923年第一次发现鸭瘟以来,世界各国学者研究其病原(即疤疹病毒)的历史进程以及在各个时期的成就,着重报道我国学者的贡献。内容有两个重点,即病毒的主要特性和疫苗的创制与应用。前者包括病毒进入机体的途径、在鸭体内的分布、形态学特点、化学成分、复制、培养、抵抗力、毒力、病原性、抗原构造、免疫原性和变异性;后者论述我国在灭能疫苗及弱毒疫苗方面的研究成果,它使我国鸭瘟的发生基本上得到控制。

The application of electron microscopic autoradiography to the study of DNA repli-cation of Duck Plague Virus(DPV) and RNA transcription in host cells is described.The major results of our experiments are: 1. The DNA synthesis of DPV occurred in the matrix of low electron density innuclei, then they accumulated in electron dense viroplast where assembly of nucleocap-sides took place. It has taken about 3 hours from the replication of viral DNA to theformation of mature viral particles. 2. The duration of DNA...

The application of electron microscopic autoradiography to the study of DNA repli-cation of Duck Plague Virus(DPV) and RNA transcription in host cells is described.The major results of our experiments are: 1. The DNA synthesis of DPV occurred in the matrix of low electron density innuclei, then they accumulated in electron dense viroplast where assembly of nucleocap-sides took place. It has taken about 3 hours from the replication of viral DNA to theformation of mature viral particles. 2. The duration of DNA synthesis in DPV was rather long. The replication ofviral DNA continued while the assembly of nucleocapsides and maturation of the viri-ons occurred. 3. The assembly and maturation of DPV occur both in the necleus and in thecytoplasm. 4. The nueleoli of infected cells kept its structure and function in RNA transcrip-tion.

应用电镜放射自显影技术研究了鸭瘟病毒(DPV)DNA复制及宿主细胞内RNA的转录功能,并扼要报导了我们的主要实验结果: 1.DPV的DNA合成是在核内电子密度较低的均匀基质中进行的,随后,转移到电子致密的毒浆结构中装配病毒核壳体。从病毒DNA复制到发育成熟的病毒仅需3小时。 2.DPV的DNA复制的持续时间较长。病毒DNA的复制与核壳体的装配及病毒的成熟与释放可同时进行。 3.DPV在细胞核内装配,也可在细胞质内装配。 4.宿主细胞的核仁依然存在,并保持其转录RNA的功能。

From January, 1980 to May, 1981, several outbreaks of a disease which occurred in three commercial duck farms in the suburb of Beijing were observed in growing ducklings under two to seven weeks of age, and the mortality was 3.1-40%. The signs most often observed were lethargy, diarrhoea, droop, incoordination and twitching, and a few affected ducklings showed torticollis and swelling of the hock joints. Post-mortem examination showed that the most frequent lesions were fibrinous epicarditis, airsacculitis and...

From January, 1980 to May, 1981, several outbreaks of a disease which occurred in three commercial duck farms in the suburb of Beijing were observed in growing ducklings under two to seven weeks of age, and the mortality was 3.1-40%. The signs most often observed were lethargy, diarrhoea, droop, incoordination and twitching, and a few affected ducklings showed torticollis and swelling of the hock joints. Post-mortem examination showed that the most frequent lesions were fibrinous epicarditis, airsacculitis and perihepatitis. The causative bacterium—Pasteurella anatipestifer—was isolated and characterized. The disease may be reproduced in healthy ducks under three weeks of age by exposure to this culture. The conclusive diagnosis as the infectious serositis of duckling was made from clinical observation, necropsy findings and the isolation of P. anatipestifer. The onset of symptoms and death could be prevented by dosing with chloramphenieol and oxytetracycline.

北京郊区三个商品鸭场,于1980年1月至1981年5月,在2~7周龄的小鸭群中发生一种死亡率为3.1~40%的疾病,其临床表现为困倦、少食或不食、共济失调和抽搐。少数慢性病例表现为歪颈或关节炎。病理剖检特点为纤维素性心包炎、气囊炎与肝周炎等。病原为鸭瘟巴氏杆菌(Pasteurella anatipestifer)。人工感染三周龄健康小鸭可发病与死亡。根据以上观察,确诊为小鸭传染性浆膜炎。
