疫病的

Risk appraisement of chestnut blight in Guangxi was made based on qualitative factor and quantity index system. The result showed that the comprehensive appraisement value of risk was 1.7128 and it meant that this disease belonged to a middle dangerous level in forestry.

通过定性因素和定量指标体系相结合的方法对板栗疫病在广西的危险性进行评估，评估结果表明，此病害的危险性综合评价值为1.7128，属于中度危险性的林业有害生物。

Alternaria-induced necrosis and chlorosis of all leaves were studied in mycorrhizal and non-mycorrhizal plants over time course and at different soil P levels.

We can make use of chip to analysis virus gene group; construct mutation detection technique of heredity diseases and become normal detection technique of many heredity diseases; supervise the changes of cell gene expression,research pathogenic theory of virus; differentiate bacteria gene types and identify bacteria strains,provide base data for screening and supervise drug-fast gene.

目前我国在出入境检验检疫中，已开始在基因芯片技术检测传染病病原方面开展了研究工作，国家质检总局动植物检疫所研制出了检测SARS病毒的全基因芯片，极大的促进了出入境检验检疫检测技术的发展，但目前国内外尚未见到有关新城疫病毒基因芯片的报道。

Based on literatures and our laboratory diagnosis for many samples from different chicken flocks with different symptoms and lesions from different areas nationwidely during the last 4 years,this article analyzed the roles of multiple immunosuppressive viral infections in pathogenesis and epizootiology in chicks flocks.

根据近几年各地大型鸡场不同类型病鸡的实验室鉴别诊断结果，结合国内外的研究进展，本文对不同免疫抑制性病毒多重感染在鸡群疫病发生和流行中的作用做了全面的分析和探索。

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。

Foot and Mouth Disease, a major threat to cloven-hoofed animals such as bovine, swine and sheep, is a highly contagious disease caused by Foot and Mouth Disease Virus. Since it has a high incidence and can easily cause an epidemic outbreak and enormous loss of economy, Office International des Epizooties ranks it in the first in all contagious diseases for domestic animals.

口蹄疫(Foot and mouth disease， FMD)是由口蹄疫病毒引起的主要危害牛、猪、羊等偶蹄动物的烈性传染病，发病率高，传染性强，并能形成国际大流行，国际兽疫局将其排在A类家畜传染病的首位。

Material of the study was FMDV from cell culture, nucleotide sequence of structural gene of FMDV and FMD vaccine strain were acquired by RT-PCR.

本试验以口蹄疫病毒的细胞培养毒为材料，通过RT-PCR方法获得了此株病毒结构基因的核苷酸序列，同法获得了口蹄疫疫苗株结构基因的核苷酸序列。

Newcastle disease is A violent contagion classified by OIE. Newcastle disease virus is a member of Rubulavirus, Paramyxovirinae, Paramyxoviridae, and a negative RNA virus which has vesica membrane.

新城疫病毒是副黏病毒科、副黏病毒亚科、腮腺炎病毒属的成员，为有囊膜的负链RNA病毒，可存在于病禽的所有组织器官、体液、分泌物和排泄物中。

Through the analysis of present condition and problem at environmentalcontrol technologies in closed poultry houses,the importance of controllingepidemic spreading from atmosphere and improving winter rearing environ-ment of poultry was expounded.

本文通过对密闭式鸡舍环境控制技术的现状及存在问题的分析，阐述了控制疫病从空气中传播以及改善冬季鸡舍环境对提高养鸡生产率的重要性。

The results showed: Each parts of intestines mucosa epithelium cell necrotized,shed off and inherent membrane exposed;Intestinal gland epithellial cell necrotized,shed off.The heart muscle cells became thinner and longer and broke down partly,and with interstitial edema.

近几年来，随着我国军犬、警犬、实验用犬和宠物犬饲养量的大幅度增加，以及异地交流日渐增多，犬感染细小病毒日趋严重，给犬饲养业带来了重大的经济损失，成为犬饲养业危害最大的疫病之一[3]。
