融合细胞具有一致的核背景，可以消除核基因的作用，因而有助于判断mtDNA突变的致病作用及机制和线粒体缺陷的致病作用及机制。

This Program Project is composed of five projects and an administrative core unit. The specific aims of Project 1 are to study the roles of SPE B, SPE A, M protein and NADase to correlate with bacterial virulence and disease severity in different clinical spectra of GAS infections. We will also study the pathogenic factors of a unique virulent clone of Ml strain caused dominant invasiue GAS disease in Taiwan in the past two years. The effects of penicillin and clindamycin on the production of SPE A and SPE B will also be determined.

本群体计画包含有5个子计画及一个行政核心计画，第一子计画的目标在於研究热原性外毒素A，B和M蛋白及NADase在A群链球菌感染中的功能及其与细菌致病力、疾病严重性的相关性，同时将针对一株最近在台湾造成侵犯性较强的A群链球菌菌株研究其致病因子的异同，并将探讨抗生素penicillin及clindamycin对於热原性外毒素A及B产生的影响。

By statistically analyzing meteorological factors affecting wheat scab outbreak, the pathogenic-day of scab was determined. The daily inducing correction index of scab in outbreak time and the duration inducing correction index of scab pathogenic-day were calculated.

方法对小麦赤霉病发生具有影响的气象因子进行统计分析，确定赤霉病致病日，计算赤霉病感病期间逐日诱发修正系数、赤霉病致病日的持续时间诱发修正系数，建立促病指数模型，判别小麦赤霉病气象条件适宜程度及发生的等级。

CG strains were isolated from the mango fruits with anthracnose symptoms in different locations on Guangdong and Hainan Province, China. The pathogenicity and sporulation capability of these isolates were compared, and the isolate LCG5 from CATAS, Danzhou City, Hainan Province, China were Chosen for further use in this study for its high virulence on mango fruits and also good sporulation capability.

分别从海口、湛江、两院三地采集到CG菌株进行纯化培养，通过芒果接种实验，对发病率、发病指数及菌株的产孢能力三项测试，最终确定选用接种发病率为100％，病情指数为71.1，菌株产孢能力达1.2×10~6个／ml的两院第5号菌株(缩写为LCG5)，其致病力比较强，产孢能力可以保证了转化体系的成功建立，方便对突变体库的致病和产孢相关突变体的筛选。

At the same time, HCV E2-CD81 interaction also may be important for the processing of viral proteins and intracellular virion formation.

因HCV与靶细胞表面相应受体的结合为其致病过程的首发事件，故此必在HCV致病机制中占极重要的地位。

Alternaria zinniae was a plant fungal pathogen isolated from a world-wide weed Xanthium occidentale, which could cause some weeds of Asteraceae disease. It was found that the fungus made disease spot on the leaf through producing secondary metabolite--phytotoxin.

百日草链格孢菌是从世界性恶性杂草苍耳罹病植株上分离得到的植物病原真菌，研究表明该菌对紫茎泽兰有致病作用，可产生致病的次生代谢产物--毒素。

Previously, it was found that the hemolytic activity of the extracellular product of V. harveyi was involved in pathogenesis in salmonids, and the most pathogenic isolate, VIB 645, contains two closely related hemolysin genes, i.e. vhhA and vhhB.

已发现哈维氏弧菌对鱼类的致病性与其分泌的胞外产物中的溶血素相关，致病力最强的菌株VIB 645有2个碱基序列非常相似的溶血素基因，vhhA和vhhB。

This paper describes the bio-typing and rapid identification technique of E. tarda briefly and discusses the virulence factors of E. tarda elaborately, including adhesion related factors, enzymes involved in anti-phagocyte killing and serum resistance, toxins, type Ⅲ and type Ⅵ secretion systems, siderophores and PST operons, in order to provide reference in researches of pathogenic mechanisms and prevention of E. tarda.

文中对迟缓爱德华氏菌的生物分型、快速检测技术等进行了简要阐述，并对该病原菌的主要致病相关因子，包括黏附因子、抵抗宿主免疫机制的酶类、各种毒素、Ⅲ型和Ⅵ型分泌系统、载铁体及磷酸盐特异转运操纵子进行了详细阐述，以期为迟缓爱德华氏菌致病机理的进一步深入研究及其防治提供参考和借鉴。

Among these are genes directly implicated in mendelian disorders, including familial hypercholesterolaemia and insulin-resistant diabetes.

这些基因当中含有单基因疾病致病基因如家族性高胆固醇血症和胰岛素抵抗型糖尿病致病基因。
