| 5. | Accurate diagnosis and effectiv veccination are main means for the prevention of porcine diarrha researh showed tha the outer capsid glycoprotein vp7 of prv particle is major protective anigen
病毒外膜的vp7糖蛋白是rv的主要免疫保护性抗原，由其刺激机体产生的抗体对中和病毒、消除感染起主要作用。 |
| 6. | Vaccination trials were carried out in spf chickens , protection index ( pi ) against md5 + rbib challenge induced by 106 pfu rfpv - gb - ha was 53 . 8 while pi against aiv challenge induced by 106 pfu rfpv - gb - ha was 69 . 5
综上所述，本论文尝试了不同禽病的主要保护性抗原基因在鸡痘病毒载体的联合表达，为探索基因工程联苗打下了基础。 |
| 7. | The high at content of the native gene is very difficult to express , we designed a new he gene by reverse the codon used for e . coli and yeast , then , the he gene was cloned into the expression vector pqe - 60
本研究尝试了其保护性抗原基因在大肠杆菌及酵母中的表达。天然bont a的hc片段基因中at含量高达76 ，其通过同义密码子置换人工合成hc段基因，将at含量降到57 。 |
| 8. | It has been showed that hepatitis b virus ( hbv ) surface antigen pres , an important protective antigen , possesses many biological functions , and thus is considered to be closely associated with establishment of hbv infection , hbv replication and assembly in hepatocytes
Hbv表面抗原前s区具有丰富的生物学功能和较强的免疫原性，前s区与hbv对肝细胞的感染、病毒复制及病毒颗粒的装配密切相关，是hbv重要的保护性抗原。 |
| 9. | The fusion ( f ) protein and hemagglutinin - neuraminidase ( hn ) are the major virulence factors of the virus to which the host responds well with protective antibody production . recombinant plasmids containing the f or hn gene can induce specific immune responses against ndv . however , dna vaccination by injection or gene gun routes is rather inconvenient and costly in field applications in scaled animal farms
融合蛋白( f )和血凝素-神经氨酸酶蛋白( hn )是ndv的主要宿主保护性抗原，以f基因和hn基因为免疫原研制的dna疫苗能诱导一定程度的免疫应答，但注射免疫或基因枪免疫途径因实际操作和成本等问题难以推广应用，而直接口服重组质粒dna免疫效果不理想。 |
| 10. | Classical swine fever ( csf ) is one of major contagious diseases in pig breeding industry . in order to gain massive diagnostic antigen csfv , and large scale of csfv specific major protective antigen protein ( e2 envelope glycoprotein ) in eucaryotic cells , which are prepared into subunit vaccine for effective prevention against csf
猪瘟是危害养猪业的主要传染病，为了得到大量的猪瘟病毒特异性诊断抗原，并试图在真核细胞中大量表达猪瘟病毒特有的免疫保护性抗原，即e2囊膜糖蛋白，为进一步制备猪瘟亚单位疫苗有效预防本病奠定基础。 |
