According to the sequence of rabbit defensin NP-1 and porcine defensin pBD-1 gene published in GenBank,We selected respectively prokaryon or eukaryotic expression vector to construct recombinant expression plasmid hoping for getting expression protein in E.coli or COS-7 cells, All these laid down a foundation in research of these two antibacterial peptides.

本文主要根据GenBank已公布的兔防御素NP-1基因和猪防御素pBD-1基因序列，分别选用原核或真核高效表达载体构建重组表达质粒，以期在大肠杆菌或COS-7细胞中得到高效表达，为进一步研究这两个抗菌肽奠定基础。

The enhancement of Immunity against diseases by oral administration of antibodies of avoid diarrhea have been reportes to be effective in prevening the infection of enterotoxic Escherichia coli and rotovirus. Suggestions have been made to fortify the immunity of young children by adding the immunoglobulins to the infant formula.

利用口服方式摄入免疫球蛋白以增强人体之免疫力已为多数学者所报导，研究发现可抑制肠毒型大肠杆菌与轮状病毒的感染，以避免下痢发生，建议在婴儿乳粉中添加免疫球蛋白以预防感染病菌。

Porringers, and Salmonella species have been detected in most spices.

For the E. coli lac operon, write the partial diploid genotype for a strain that will produceβ-galactosidase constitutively and permease by induction.

以大肠杆菌的乳糖操纵元为例，请写出一菌株的部分二倍体基因型：β-半乳糖苷酶是组成型表达的，透过酶是诱导表达的。

Glutamine-binding protein is one of the ligand-specific periplasmic binding proteins in the Escherichia coli permease systems, predicted to play an important role in transferring Gln from the pe-riplasmic space to the cytoplasmic space.

谷氨酰胺结合蛋白(Glutamine-binding protein， GlnBp)是大肠杆菌透性酶系统中一个细胞外液底物专一性结合蛋白，对于细胞外液中谷氨酰胺的运输和传递至关重要。

Three plasmids named pBSGt pBSGd and pBSGk were constructed respectively with two plasmids named pEGH and pBS305. The plasmid pEGH contained gfp gene and pBS305 is an E. coli -Rhodococcus shuttle vector. These constructed plasmids can be used to detect the efficiency of promoter.

以带有报告基因gfp的质粒pEGH和大肠杆菌-红球菌穿梭载体pBS305为出发质粒，构建了三个带有不同启动子的表达质粒pBSGt、pBSGd和pBSGk，电击转化红平红球菌LY822。
