致病

Many pathogens of animal and plant, such as Erwinia cawtovora pv.carotovora and Pseudomonas aeruginosa, producing some kinds of virulence factors before attacking the host, and most of those virulence factors was modulated by the quorum-sensing system which relys on the secret of some small quorum sensing signals.

很多动植物的病原细菌，包括胡萝卜软腐欧文氏菌和铜绿假单胞菌等在侵染动植物有机体的过程中，首先利用细菌的群体感应机制诱导致病因子的表达，在致病因子的作用下侵染宿主。

An administrative core unit will be set up with missions of taking care of all the exter

综合而言，以这样一个高度整合的研究计画，从临床、实验及治疗的方向在病人、细菌、细胞层次、和分子层次作系统性的研究，探讨热原性外毒素B及其他致病因子的功能，将会有助於我们对於A群链球菌的致病作用进一步了解，更重要的是这些资讯将会提供临床治疗的新策略。

Medical care and health institutions, anti-epidemicagencies and units engaged in the experimentationofpathogenic microorganisms must rigorously implementthe management system and the operation procedures stipulated by the health administration department under the State Council to prevent the iatric infection of infectious diseases, inside-hospital infection, laboratory infection and the spread of pathogenic microorganisms.

第十五条医疗保健机构、卫生防疫机构和从事致病性微生物实验的单位，必须严格执行国务院卫生行政部门规定的管理制度、操作规程，防止传染病的医源性感染、医院内感染、实验室感染和致病性微生物的扩散。

The toxin is a secondary metabolizable production in the pathogenic process of many pathogens,which can cause necrotic spot of the host. So it is a poisonous factor and it is important to the pathogenic activity.

毒素是许多亲和性植物病原菌致病过程中产生的次生代谢产物，离体使用可造成相应的寄主表现坏死斑反应，因此是病原菌的毒性因子，对决定病原菌的致病性有很重要作用。

All of the hygromycin B-resistant transformants tested were mitotically stable after several subcultures onto complete medium without hygromycin.

用大麦叶片离体接种的方法快速测定部分稻瘟病菌转化子的致病性，发现一个致病缺陷突变体：Al-412。

Preliminary location of the nosogenic gene was carried out successfully. It is the foundation of clone of the nosogenic genes and might be widely used for gene diagnosis in the fijture.

成功地对致病基因进行了初步定位，为进一步克隆致病基因，进而实现临床上疾病的基因诊断奠定了基础。

Objective To find out the related mechanism, characters, factors and rules of psychological stress- emotions pathopoiesis with scientific methods, provide new foundation to the research of psychological stress- seven emotions pathopoiesis.

目的用科学的方法探索心理应激—情志致病产生的相关机理、相关特征、相关因素，相关规律，为心理应激—中医七情致病的研究提供新的依据。

Specific pathogen free chicken ; Escherichia coli ; mildly pathogenic avian influenza virus ; synergistic pathopoiesis effects ; immunosuppression

SPF鸡；大肠杆菌；低致病性禽流感病毒；协同致病；免疫抑制

The endotoxin also named as lipopolysaccharide in the outer membrane of Gram-negative bacteria is the primary constituent of pathopoiesis. LPS which has extensive biological activity can induce severe inflammation in cascade and lead to sepsis、systemic inflammatory response syndromes、multiple system organ failure.

细菌壁外膜的内毒素又称脂多糖(lipopolysaccharide，LPS)是其主要致病成分，具有广泛的生物活性，能引起严重的炎症级联反应，是导致脓毒症、系统性炎症反应综合征、多脏器功能衰竭的主要致病因子。
