细菌毒素的

This toxin is a combination of three proteins produced by a bacterium.

这种毒素是由一种细菌产生的三种蛋白质合成的。

RTX is domain of bacterial toxins, which has not been found in cysteine proteases in plant.

RTX结构域是细菌毒素家族蛋白所具有的一个功能域，在目前发现的植物半胱氨酸蛋白酶氨基酸均不含有RTX结构域。

"Diverticulitis:Inflammation of a diverticulum or of diverticula in the intestinal tract, causing fecal stagnation and pain."

肠毒素由只限于肠结胸的细菌而产生的毒素，引起呕吐和腹泻并导致食物中毒

The new findings appear to represent the first known case in which spore formation—also known as vegetative reproduction—depends on the presence of ano the r organism.

研究小组之前的工作曾显示，这种细菌在真菌对水稻幼苗表现出来的毒素方面起到了关键的作用：细菌产生了一种造成幼苗枯萎的植物毒素。

But we have seldom found the reports about it in China; So writer summarized some literature more than twenty years; name,classification and family of hemolysin have been written, especially three of representative species:α-toxin, Streptolysin O and HlyA; Nowaday, A relationship between the hemolysin and pathopoiesis of bacterium is obvious.

另外，细菌溶血素的英文命名并不统一，检索时容易造成漏检或误检；通过查阅大量英文文献资料，归纳汇总近20年报道的溶血素研究进程；该文详细列出了细菌溶血素名称、分类以及各溶血素家族列表。并且分别介绍了其中三种典型的穿孔毒素：葡萄球菌α-毒素、链球菌溶血素-O、埃希氏大肠杆菌溶血素HlyA。

The author in recent years used the traditional Chinese medicine phlegm hot clear treatment acute pneumonia,the research indicated that,the refrigeration antidote in vitro bacteriostasis,the sterilization,the neutral bacteriotoxin and the anti-viral function effective concentration was in vivo achieves with difficulty,its treatment function was the anti-infection,the anti-inflammation,the disintoxicating,the promotion organism immunity function common result.

笔者近年来采用中成药痰热清治疗急性肺炎，研究表明，清热解毒药在体外的抑菌、杀菌、中和细菌毒素和抗病毒作用的有效浓度是体内难以达到的，其治疗作用是抗感染、抗炎、解毒、促进机体免疫功能的共同结果。

One kind, the antitoxins, neutralize s poisons produced by certain bacteria.

其中一种为抗毒素，可中和某些细菌产生的毒素。

The main virulence factors are CPS, LPS, OMP, TBP, adhesion factors, Apx, Urease and so on. A. pleuropneumoniae produces proteinaceous cytotoxins that is the main virulence factors, ApxⅠ, ApxⅡ, ApxⅢand ApxⅣ. ApxⅡis expressed by all serotypes of A.

Apx毒素是APP最主要的毒力因子，现证明不同血清型的菌株可产生4种Apx，ApxⅡ除血清型10和14以外，其它血清型都分泌；任何血清型都能在体内分泌毒素蛋白ApxⅣ，但体外培养的细菌却不能分泌该毒素。

The toxins produced by the staph bacteria may result in kidney failure.

所产生的毒素的葡萄球菌细菌可能会导致肾功能衰竭。

By suspending cell culture from the callus of P. thugbergii and by fluorescent observation, a new method, which is easy and sensitive to observe cell activity and to test the phytotoxicity of various bacteria, was used. This method can be utilized to study the bacterial toxins. Cultured filtrates of some strains of the nematode-carrying bacteria were bioassayed for their toxicity to suspending cultured cells from P. thugbergii callus. Strong toxic effects were observed by the filtrates of Pseudomonas spp., P. fluorescence, and Sphingomonas spp., these bacteria species are coincide with those in the early stage of pine wilt disease.

本试验使用了黑松愈伤组织的细胞悬浮培养方法，用荧光方法观察各种细菌对植物细胞的毒性测定，这种方法具对细胞的活性观察容易、灵敏度高等特点，证明可用于细菌的毒素研究；对松材线虫携带的细菌的部分菌株，用其培养滤液对黑松愈伤组织的悬浮培养细胞的生物测定初步证明，松材线虫携带的细菌中以假单胞菌、荧光假单胞菌和少动鞘氨醇单胞菌的滤液对黑松细胞具有较强的毒性，这与松树发病早期出现的细菌种类相一致。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
