大肠杆菌

A type 3 fimbriae display system in Escherichia coli was subsequently constructed to determine the effect of MrkD allelic variation on the fimbrial activity.

接著，我们以大肠杆菌JM109为表现载体构筑了表现第三型纤毛的重组质体，分别带有mrkDV1，mrkDV2，mrkDV3和mrkDV4基因型。

LT and ST are the main enterotoxins of enterotoxigenic \$Escherichia coli \$found in clinical isolates, and CS3 (the common antigen in the CFA/Ⅱ family of fimbrial antigens) is one of the most prevalent antigens of colonization factors.

不耐热肠毒素和耐热肠毒素是产肠毒素大肠杆菌的主要致病因素，CS3为该菌的优势定居因子，是定居因子CFA/II菌毛抗原的共有抗原组分。

The 7.4 kb DNA fragment containing the S. Choleraesuis std fimbrial gene cluster was PCR amplified and cloned into the pCR-XL-TOPO vector. The open reading frames of the std fimbrial gene cluster were analyzed. The resulting recombinant DNA was transformed into Escherichia coli HB101 strain.

本实验室藉由PCR方式，增幅7.4 kb的std线毛基因组，将其选殖至pCR-XL-TOPO质体DNA，委外定序后，分析std线毛基因组之开放性读框，进而将此重组DNA送入大肠杆菌HB101，并藉由RT-PCR及西方点墨试验观察到S。

The dominant bacteria are Sphlingomonas paucimobilis, Chryseomonas luteola, Enterobacter doacoe etc.; and some pathogenic bacteria of animal and mankind such as Aeromonas salmonicida、Flavobacterium meningosepticum also appear....

在潮间带生物体内和表层海水中各类细菌数量均较高，其中潮间带生物体内细菌总数平均为8×105个/g、粪大肠杆菌数平均为9×102个／g、弧菌数平均为1.5×105个／g，不同的潮间带生物中，细菌数量相差很大。

Blood samples were obtained on 0,2,4,6 and 8 days after admission. Dynamic changes of immunological parameters including serum IgA,IgG,IgM,complements (C3,C4) levels were determined in each group at various intervals following trauma. Phagocytosis of monocytes was also measured by use of phagotest kits after blood cells were incubated with fluorescin isothiocyanate-labeled E.

分别在入院时及入院后2、4、6和8 d留取外周静脉血，检测血清免疫球蛋白(IgA、IgG、IgM)与补体(C3、C4)水平的动态变化，全血细胞与用异硫氰酸荧光素标记的大肠杆菌共孵育后检测单核细胞噬菌能力。

The fusion expression vector and the non-fusion expression vector were constructed by the open reading frame of annfaf expressed specifically in strawberry Fragaria ananassa Duch.

将草莓？穴Fragaria ananassa Duch。？雪果实中特异表达的膜联蛋白基因annfaf的cDNA连接重组到pET-30a质粒中，构建了融合和非融合蛋白表达载体。annfaf 基因转化大肠杆菌E。

An expression vector was constructed with a safe marker gene, 6-phosphomannose isomerase, and an insect-resistant gene, Galanthus nivalis agglutinin, was used in rice genetic transformation in the present study.

采用农杆菌介导法将来源于大肠杆菌的6-磷酸甘露糖异构酶安全选择标记基因和雪花莲凝集素抗虫基因构建于同一表达载体上进行遗传转化，获得带有安全标记基因的抗褐飞虱转基因植株。

Bacteria and other organisms such as Escherichia coli, Salmonella or Giardia lamblia can also be a cause.

细菌和其他生物体，如大肠杆菌，沙门氏杆菌或贾第鞭毛虫也可以成为事业。

Frontier will remove pathogens and contaminants down to 2 microns in size including Giardia, Cryptosporidium and E.

可去除大小超过2微米的广泛传播的病原微生物和污染物如贾第鞭毛虫、隐孢子虫和大肠杆菌等细菌。

Frontier will remove pathogens and contaminants down to 2 microns in size including Giardia, Cryptosporidium and E.Coli*.

可去除大小超过2微米的广泛传播的病原微生物和污染物如贾第鞭毛虫、隐孢子虫和大肠杆菌等细菌。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
