致病

Among parasites, protozoa are usually more pathogenic than nematodes.

在寄生虫中，原虫的致病性往往比线虫的要高。

On the other hand, the vendors here prepare the food right in front of you, and everything is well-cooked.

这里的小吃现煮现吃，而且都熟到冒泡，这样其实更卫生，而且也没有会致病的怪细菌

Null mutant Δmnh6 produced appeared offwhite hyphae, showed reduction in growth, conidiation and appressorium formation, and also showed reduction in appressorium turgor pressure. And the hyphae were more readily wettable by a solution containing SDS and EDTA and more easily digested by fungal cell-wall-digesting enzymes. The appressoria produced by Δmnh6 mutants showed diminished host penetration and the infectious hyphae of Δmnh6 mutants showed reduced in planta growth. Targeted deletion of mnh6 resulted in the greatly reduced virulence capacity to barley and rice CO39 in infection assays.

突变子Δmnh6的菌落形态不同于野生型GUY11，菌落呈灰白色，菌丝稀疏，生长速度变慢，产孢菌丝细胞壁的溶剂疏水性消失，菌丝细胞壁容易被细胞壁降解酶降解，产孢减少，孢子形态变得细长，孢子的附着胞形成率降低，附着胞的膨压降低，附着胞对寄主植物表面的穿透能力减弱，侵入后生长速度减慢，喷雾接种后对大麦和水稻CO39的致病性消失。mnh6基因重新引入Δmnh6后，突变子的表型恢复。

Several hrp mutants, which losted their ability to trigger hypersensitive response on nonhost plant tobacco and to be pathogenic on rice, were produced from Xanthomonas oryzae pv.oryzicolaby chenmical mutagenesis.

化学诱变水稻条斑病细菌（Xanthomonas oryzae pv.oryzicola，Xooc），获得了在水稻上丧失致病性和在非寄主烟草上丧失激发过敏反应的hrp基因突变体。

To study the existence of transfusion transmitted virus in liver tissue taken from the people with no viral hepatitis and it's pathogenicity.

检测非病毒性肝炎人群肝组织中经输血传播病毒感染情况，探讨其致病性。

The results provide insight into the risk of SSIs in relation to previous transplantation, choledocho-jejunal reconstruction, and red blood cell transfusion, which could motivate new studies to aid in understanding the pathogenesis of SSIs in liver transplantation.

研究结果提供了SSI和移植病史、胆总管-空肠重建和红细胞输注之间的关系的新的视角，有助于推动肝移植术后致病机理的更深入的研究。

The results indicated that the mechanism of induced resistance to tomato bacterial wilt may be the changes in metabolism related to the resistance.

这表明青枯无致病力菌株产生诱导抗性的机制可能是植物本身的抗病代谢过程被激活了。

Tobacco tomato spotted wilt disease was found in many provinces.This disease is widely distributed in Yunnan production tobacco area and it causes above 60% losses in some area. The tomato spotted wilt disease is one of the most potentially dangerous disease of tabacco in the world. This paper reviewed the distribution,symptomology, causal agents, pathogenic mechanism, the composition and function of virus genome and epidemiology and management of the tobacco tomato spotted wilt disease.

目前该病在中国许多省均有发生的报道，在云南烟区广泛分布，在局部地区可造成60%以上的严重损失，烟草番茄斑萎病被认为是世界上对烟草最具潜在危险病害之一，较为系统全面的综述了烟草番茄斑萎病的发生与分布，病害症状学，病原物，致病机制，病毒基因组结构和功能以及病害的流行及控制等方面的研究进展。
