查询词典 pathogenicity

Precocious Shanxi strain ( E.tenella SX010323) was developed via the method founded by Jeffers, and the corresponding endogenous development stages, pathogenicity, reproductive potential, immunogenicity and stability were observed and detected.

运用Jeffers建立的早熟系选育方法对柔嫩艾美耳球虫山西株( E.tenella SX010323)进行早熟选育，并对其内生发育、致病性、繁殖力、免疫原性、稳定性进行观察和检测。

An h-VRSA strain isolated from clinical specimen was induced to increase its resistance to vancomycin in vitro. The coagulase, lecithinase, hemolysin of this resistant strain and its pathogenicity to laboratory animals were examined in comparison with that of the standard S. aureus ATCC29213 strain.

使用万古霉素体外诱导方法将h-VRSA在体外逐渐诱导为VISA，通过对侵袭性酶、毒素的检测及动物致病性观察，并与金黄色葡萄球菌标准菌株比较，了解其致病性的变化规律。

The results showed that when the proportion of the resistant subpopulation within the h-VRSA was low, te level of the toxic factor and its pathogenicity to animals had no difference from that of the standard strain. If proportion of the resistant subpopulation increased the level of coagulase and lecithinase changing from positive from negative and the ring of hemolysis disappeared. The speed of proliferation of the organisms in the animal slowed down and the LD50 increased.

结果 当试验菌株中耐药亚群的比例较少时，其毒力因子及动物致病性检测结果与金葡菌标准菌株无显著差异；随着试验菌株中耐药亚群的比例增加，表现为血浆凝固酶、卵磷脂酶由阳性转为阴性，血琼脂平板上溶血环消失，细菌在动物体内增殖速度减慢，对动物的半数致死量(LD50)增加。

The result is identical basally with past one about pathogenicity mensuration.

该分类结果与以往的致病性测定小种划分基本一致。

The life cycle and pathogenicity of E.stigmosa were observed chronologically. There might be only one merogony stage in the life cycle of E.stigmosa. Each meront contained 3-5 merozoites.

结果，在内生性发育过程中，多斑艾美球虫可能仅有1个世代的裂殖生殖阶段，每个裂殖体含3～5个裂殖子。

And it also showed that the inheritance of the growth-rate and pathogenicity to cotton seedlings of XC-6 could not be inherited steadily in zoospore progenies and oospore progeny, but the colony morphology and homothallic character of XC-6 could inherited steadily in both asexual and sexual progenies, which suggested that the inheritance and variation of the above characters might be related to long-selfing and hybridization in species.

同时，XC-6生长速率、对棉苗的致病力、菌落形态及同宗配合遗传和变异特性研究表明，其生长速率和对棉苗的致病力性状在单游动孢子后代和自交后代均不能稳定遗传，但菌落形态和同宗配合特性在单游动孢子后代和自交后代均能稳定遗传，提示上述性状在单游动孢子后代和自交后代的遗传和变异特性可能与菌株长期自交和种内杂交有关。

And it also showed that the inheritance of the growth-rate and pathogenicity to cotton seedlings of XC-6 could not be inherited steadily in zoospore progenies and oospore progeny, but the colonyKey words: Phytophthora boehmeriae, Biological character, Inheritance

同时，XC-6生长速率、对棉苗的致病力、菌落形态及同宗配合遗传和变异特性研究表明，其生长速率和对棉苗的致病力性状在单游动孢子后代和自交后代均不能稳定遗传，但菌落形态和同宗配合特性在单游动孢子后代和自交后代均能稳定遗传，提示上述性状在单游动孢子后代和自交后代的遗传和变异特性可能与菌株长期自交和种内杂交有关。

They affect the development of organismal characters such as sex determination,the functional determination of centromeres,the development of Drasophila's eys,the prion pathogenicity and cancer formation greatly.

它对生物体的性状发育如性别决定、着丝粒的功能决定、果蝇复眼发育、朊病毒致病性的获得及癌的发生等等方面有着重要的影响。

Evansi/HGPRT- could proliferate in the medium without HT and its pathogenicity to mice declined with the parasitemia and death of the inoculated mice to be delayed double than the control group.

生物学试验表明，HGPRT缺陷株在无HT的培养液中生长良好，对小鼠致病力有下隆的趋势，虫血症和小鼠死亡时间比对照组延长1倍多。

A series of interactions such as nematode pathogenicity, host susceptibility and host resistance could form due to parasitism.

寄生过程引起的根结线虫与寄主植物之间的一系列互作反应，包括根结线虫对寄主植物的致病现象，寄主植物的感病反应和抗病反应。

Pradeep Indulkar, a senior official at the Maharashtra state Home Ministry say 101 human were killed and 287 injured.

马哈拉施特拉邦内政部高级官员Pradeep Indulkar称，有101人在冲突中丧生，287人受伤。

Mark Frei, a senior vice president of West, says 80% of West's homeagents have some college education, compared with 30% of those whowork in office-based call centers.

Frei说，该公司80%在家办公的人员都拥有本科学位，而在公司电话中心工作的人中只有30%拥有本科学位。
