基因Ⅲ型和Ⅳ型新城疫病毒全基因组测序及其在新城疫进化史中的重要地位分析根据EMBL/GenBank中已发表的基因Ⅲ型NDV全基因和基因Ⅸ型NDV基因片段设计一套全基因引物，将NDV全基因分为10个相互重叠的片段进行RT-PCR扩增。

From June to September in 1985, an epizootic disease occurred tn rainbow trout fingerlings in the farm of Shuoxian county, Shanxi province, The strains that isolated from the liver, kidney and spleen of the diseased rainbow trout were shown to be the cause of the disease by infection experiments.

1985年6～9月间，山西省虹鳟鱼实验场鱼种爆发了一起细菌性疾病，从病鱼的肝、脾、肾中分离到细菌，用此菌人工感染虹鳟能得到与天然发病病鱼相似的症状，并从被感染鱼的体内重新分离到这种菌，证实为该病病原菌。

The phylogenetic analysis showed that QH3,HLJ and A4 belonged to the genetype Ⅷ,Ⅸ,Ⅵ respectively. It indicated that not only NDV genetypes among epizootic strains isolated from different areas were evidently variable, but also special genetype DC which hadnt prevailed in abroad was present in China.

表明我国NDV流行毒株在各地区之间具有明显的基因型差异，而且还具有不同于国外流行的我国特有的基因型——基因Ⅸ型。

The novel primers were evaluated by detecting BTV serotypes 1, 3, 5, 8, 10, 11, 21 and 22. The specificity of the primers was estimated by comparing to gene sequences of viruses published in GenBank, and further assessed by detecting BTV serotype 1-12 and Epizootic hemorrhagic disease virus serotype 1-4. The sensitivity and repeatability of PCR with the novel primers were evaluated by successfully detecting the recombinant plasmid pGEM-T121 containing the diagnosed nucleotide sequence.

Blast软件分析引物与GenBank发表的病毒基因的同源性，显示引物特异性较好；利用8个不同血清型BTV标准毒株进行RT-PCR检测，证实该引物能有效检测不同血清型BTV；通过BTV1-12和EHDV1-4进行检测，证实该引物具有较好的检测特异性；通过制备的含特检序列的质粒标准品P121进行检测，显示该引物检测的敏感性为105 copies，重复检测CV%为0；对模拟血清样品进行检测，结果均为阳性。

The phylogenetic analysis showed that QH3,HLJ and A4 belonged to the genetype Ⅷ,Ⅸ,Ⅵ respectively. It indicated that not only NDV genetypes among epizootic strains isolated from different areas were evidently variable, but also special genetype DC which hadn't prevailed in abroad was present in China.

表明我国NDV流行毒株在各地区之间具有明显的基因型差异，而且还具有不同于国外流行的我国特有的基因型——基因Ⅸ型。

However, the RT-PCR failed to detect NDV, ILTV and GPV. The results showed that the established Multiplex RT-PCR technique provided a more sensitive method for diagnosis and epizootic study of the IBV.

该方法对793/B血清型可检测到582bp和891bp两条核酸片断，其他的血清型只出现582bp一条核酸片断，而新城疫病毒、传染性喉气管炎、鹅副粘病毒菌未检测到特异型条带。

Twigg has proposed, on the basis of English evidence from the medieval period, that bubonic plague was impossible because of the lack of an epizootic among black rats (they must die before their fleas can escape to human hosts), the need for a suitable temperature to permit fleas to survive in numbers large enough to create demographic havoc, and the far too rapid spread of the pestilence.

一旦使得跳蚤大量存活，以至于造成大规模灾难发生的温度得到满足，传染病蔓延就会越迅猛的多。他还排除了肺鼠疫，因为它过于自我限制以至于不能成为一个合理的选择。

An investigation on an epizootic of Nocardia seriolae (507, 336, 300 and 531) infected of sea bass, strip bass and largemouth bass occurred at Yulin in Taiwan, respectively.

由云林县养殖鱼塭中罹病之七星鲈鱼、条纹鲈鱼及大嘴鲈鱼所分离奴卡氏菌菌株，经生化性状试验结果，初步鉴定与 Nocardia seriolae 相似。

In the past three months, the horse has not been to any establishments where epizootic lymphangitis, equine infectious anaemia, equine influenza,equine rhinopneumonitis, equine viral arteritis, equine piroplasmosis, Borna disease, Surra, Japanese encephalitis, West Nile fever, contagious equine metritis, rabies, horse pox, anthrax or any other notifiable disease of horses has been reported.

在过去3个月内，参赛马所在的马场，没有发生下列疫病的临床病例：流行性淋巴管炎、马传染性贫血、马流感、马鼻肺炎、马病毒性动脉炎、马梨形虫病、博纳病、苏拉病、日本脑炎、西尼罗热、马接触传染性子宫炎、狂犬病、马痘、炭疽或其他须通报的疫病。
