不致病的

The role of migratory birds in the spread of highly pathogenic avian influenza is not fully understood.

候鸟在高致病性禽流感病毒的传播中所起的作用还不完全清楚。

The damage of hepatic kupffer cells function and intestine mucosae protective screen function caused cooperatively by ischemia, hypoxia, microcirculatory disarrangement, inflammatory mediators (O〓, OH〓 etc) and cytokines (TNF-α, IL-1, IFN-γetc), the functional damage easily results in bacterial translocation and endotoxemia, as the damage mitigates the clearance of bacteria and toxin.

缺血、缺氧、微循环障碍、炎症介质及细胞因子（TNF-α、IL-1、IFN-γ等）共同作用，使肝脏Kuppfer细胞和肠粘膜屏障功能受损，对内毒素清除能力减弱致内毒素血症，是肝功能衰竭的重要病生环节，亦是继发多脏器衰竭的始动因素，但ALF致病确切机制目前尚不十分清楚。

To ensure the system is not re-infected with pathogenic micro-organism, the filling water must be reliablydisinfected by AQUADES-UV technology!

要确保那系统不会再受到致病微生物的感染，所有盛水必须利用有可靠性的AQUADES-UV 紫外线技科来消毒。

While it does not seem to be highly pathogenic, human to human transmission has been observed.

尽管似乎不是高致病性的，但仍发生了人与人之间的传染。

Phenotype-genotype analysis showed that both the penetrance and severity of phenotype correlate with expansion size.

HOXD13蛋白N端功能、多聚丙氨酸的作用及多聚丙氨酸延展突变的致病机制尚不十分清楚。

Objective To analyze the clinical manifestations and antibiotic susceptibilities of Acinetobacter infection of the lower respiratory tract in the elderly patients with chronic pulmonary heart disease.

目的 了解老年慢性肺心病患者下呼吸道不动杆菌感染的致病特点和对抗生素的敏感性。

Anti-bacteria and anti-virus: Modern science believes that the acacatechin can resist a lot of malignant bacteria in human body such as the Clostridium botulinum, while avoid harming the reproduction of probiotics we need in our intestine such as the lactic acid bacteria. Therefore, it can adjust the intestine.

抗菌及抗病毒功效：近代科学研究认为儿茶素类对委很多引起人体致病细菌，例如肉毒杆菌有抑制效果；另一方面又不伤害肠内有益菌群的繁衍，例如乳酸菌，因此有整肠的功效。

This may partially attribute to packaging an inclusion within the hydrophobic exosporium so as to keep the inclusion in the water where target larvae maybe actively feeding.

可能是因为芽胞在昆虫肠道内再次萌发，产生了其他致病因子，如肠毒素、溶血素等，与杀虫晶体蛋白协同作用；也可能是因为伴胞晶体受到疏水的芽胞外壁层保护而能在水中等一般伴胞晶体不容易存在的地方被易感昆虫摄食。

However, the mechanisms by which H. pylori mediates pathogenesis are still unclear.

然而，目前对於胃幽门螺旋杆菌的致病机转尚不清楚。

Until now, whether PCV2 replicates in immune system and the pathogenesis of PMWS are still not well understood.

截至目前为止，PCV2是否会於免疫系统内复制以及PMWS的致病机制仍不甚清楚。
