There are three sections in this dissertation: 1 quantification of gene expression in chicken embryo fibroblasts and virus load in bursal Fabricius infected with infectious bursal disease virus, the recombination of infectious laryngotracheitis virus and pathotyping of Newcastle disease virus.

本论文包括三个部分：1传染性法氏囊病病毒对鸡成纤维细胞某些基因表达的影响和病毒在法氏囊与粪便中的定量研究；2传染性喉气管炎病毒的重组；3新城疫病毒的分型研究。

The ORF2 gene is the most important protein-code gene for porcine circovirus, and is the main gene differing porcine circovirus typel from porcine circovirus type2 (PCV2). To construct a specific PCR detecting method, we designed a pair of primers to amplify a partial fragment of ORF2 gene from PCV2, referring to fifteen strains complete genome published in Genbank. The PCR product was about 0.67kb in size detected by gelose gel electrophoresis.

猪圆环病毒的开放阅读框2(ORF2)是其主要结构蛋白的编码基因，也是区分猪圆环病毒1型(PCV1)和猪圆环病毒2型(PCV2)的重要基因，本研究参照GenBank已发表的15株PCV2基因序列，设计合成一对引物，对PCV2的ORF2基因进行PCR扩增，产物经琼脂糖凝胶电泳，呈现一条大小约0.67kb的特异条带，经条件筛选，建立了猪病料中PCV2感染的PCR检测方法。

It was shown that the epidemic of an extremely sever form of cassava mosaic disease in Uganda is not only associated with ACMV, but also associated with a new virus.

本文表明乌干达严重木薯花叶病流行不仅与非洲木薯花叶病毒有关，还与一种新病毒有关，这种新病毒由EACMV和ACMV基因组间重组产生。

Cymbidium mosaic virus and Odontoglossum ringspot virus are two most prevalent viruses of orchids .The commercial value of an orchid can be reduced considerably when it becomes diseased.

喜姆比兰嵌纹病毒(Cymbidium mosaic virus， CymMV)与齿舌兰轮斑病毒(Odontoglossum ringspot virus， ORSV)为两种最普遍的兰花病毒，罹病兰花的商业价值会因而大幅降低。

The study needs enterovirus infections data in Taiwan from 1999 to 2005. The sources of data include the sentinel surveillance system, the Notifiable disease reporting system and the contract lab data. Statistical methods used for the analysis of seasonal variation include graphics, chi-square test for goodness of fit, method of decomposition and circular distribution.

使用之研究材料为1999年至2005年台湾肠病毒的监测资料，包括定点医师於每周报告之手足口病与疹性咽峡炎病例、法定传染病中应报告的肠病毒感染并发重症确定病例与病毒性感染症合约实验室之肠病毒感染检验阳性病例，分别应用绘图、卡方适合度检定、分解法与圆形分布法进行分析。

Tobacco mosaic virus plays an very important role in the discovery of virus and several pioneers made contributions to the developmental process of virology, through which the brief history of discovery of virus can be traced.

烟草花叶病病毒在病毒的发现中有着极其重要的地位，几位病毒学研究的先驱在这方面的研究有极大的贡献，以此为线索可以看到病毒被发现的简要历史。
