枯草芽孢杆菌NCD-2菌株是一株有效防治棉花黄萎病的细菌，它通过产生抑菌物质达到对大丽轮枝菌的抑制作用。

We study the dynamical behavior of the epidemiological model with pathogen mutation on small-world networks, and discuss the influence of the immunity duration $\tau_{R}$, the cross-immunity threshold $h_{thr}$, and system size $N$ on epidemic dynamics.

我们研究了一种病毒变异传播模型在小世界网络中的动态行为，讨论了免疫时间$\tau_{R}$，交叉免疫阈值$h_{thr}$和系统大小$N$对传播动力学的影响。

If only 10 of the select agents that might be stable in milk are considered, the cost of testing each dairy tanker truck load for each pathogen increases to $210,000,000, regardless of other chemical or nontraditional threat agents that might be of concern.

假如我们考虑把10种所选的药剂安放在牛奶中，并且排除药剂自身的化学与非传统威胁的顾虑，那么所用于检测每日运载病原体的大油车的费用将升至$210，000，000。

The disease is called the mad dog disease in ordinary Chinese language, for it is always caused by dogs' biting which carry the pathogen, and the patients with the disease always appear to be mad and finally dead in a short period.

这种病之所以被称为狂犬病是因为通常被携带病原体的狗咬伤，最后发展成为狂躁的精神症状，并在短期内死亡。

With the exception of healthcare professionals performing procedures that can be considered to be at risk of transmission and designated first aiders, there should be no obligation for an employee to inform his/her employer whether he/she is infected with a blood borne pathogen.

除了工作过程中被认为有传染风险的保健从业者和指定的第一助手，雇员没有义务告知其雇主是否他/她被血液病原体感染。

Ascospores require free moisture plus a food base such as senescent flower petals or damaged tissue to produce a small colony that can then infect the plant. The pathogen produces oxalic acid and numerous enzymes that break down and degrade plant tissue.

在自然湿度和衰老的花瓣、损坏的组织等良好的营养基础上，子蘘孢子产生小菌落，这些小菌落接着就能够浸染植株，病菌产生草酸和大量的能够分解和降解植物组织的酶。

Methods After Candida albicans were inoculated into the specific pathogen free mice, the total amount of Candidas in cecum and the amount of which attached to the mucosal membrane were counted at different interent intervals. The lymphocyte proliferation in Peyer's patch and in lamina proper was shown by BrdU incorporation, meanwhile B cells isotype switch in PP was investigated. IgA plasma cells were shown by immunohistochemical staining. Specific IgA antibodies to Candida albicans were measured with ELISA.

采用无特殊病原菌动物经口喂入白念菌，在不同时相处死后，观察肠内白念菌总数及肠粘膜表面白念菌粘附数量；取肠系膜淋巴结做白念菌选择培养，观察移位体内发生率；采用Brdu体内掺入显示局部粘膜淋巴细胞的增殖情况；流式细胞计数潘伊尔氏结细胞表面IgA阳性率；免疫组化染色后计数固有层中IgA浆细胞数量变化；ELISA法测定肠粘液中特异抗白念菌IgA含量。

The 59 pure cultural isolates, including 3 Fusarium oxysporum f.sp.cucumarinum, 26 other Fusarium isolates and 20 fungi, 6 bacteria, 7 actinomycetes from cucumber rhizosphere, have been detected by PCR-RFLP and Nested-PCR. It shows that PCR-RFLP is special for the pathogen of Cucurbits Fusarium Wilt, and Nested-PCR is special for Fusarium oxysporum f.sp.cucumarinum.

本论文应用PCR-RFLP和巢式PCR程序对3株黄瓜尖镰孢菌(Fusarium oxysporum f.sp.cucumarinum)、26株镰孢属部分真菌及分离自土壤的20株真菌、6株细菌和7株放线菌共59个菌株进行扩增，表明PCR-RFLP程序对瓜类枯萎病菌具有特异性，而巢式PCR对黄瓜尖镰孢菌具有特异性，巢式PCR程序检测黄瓜尖镰孢菌的特异性高于PCR-RFLP程序。

The primers and the detection programs have been used to detect the pathogens in the inoculated-diseased cucumber plants .The details are reported as follows: 1. By using the primers ITS1/ITS4, only Fusarium isolates could be amplified to produce a special fragment of 750bp. This product generated 480bp, 200bp and 100bp fragments after digested by restriction enzyme HinfⅠonly from the pathogen of Cucurbits Fusarium Wilt.

引物ITS1/ITS4只在镰孢属菌株上扩增到一条750bp分子片段，其他供试菌株无扩增条带产生，扩增产物经HinfⅠ酶解后，只有瓜类尖镰孢菌产生480bp、200bp和100bp 3条带，说明该PCR-RFLP程序对瓜类尖镰孢菌具有特异性；巢式PCR引物BIK1/BIK4和BIK2/BIK3只有在黄瓜尖镰孢菌菌株上扩增到一条800bp分子片段，其他菌株均无扩增条带产生，说明该巢式PCR程序对黄瓜尖镰孢菌具有特异性。

The pathogen must be susceptible to the eluted antibiotic.

病原体必须对所选抗生素敏感。

Do you know, i need you to come back

你知道吗，我需要你回来
