摘要: 试验旨在构建表达鸡新城疫病毒(NDV)HN基因的重组减毒鼠伤寒沙门氏菌SL1344ΔcrpΔasd(pYA3493-HN)。以pMD18-T-HN为模板,通过PCR扩增出NDV HN基因片段,定向插入原核表达载体pYA3493中,将重组表达质粒pYA3493-HN转入χ6097,再转入减毒鼠伤寒沙门氏菌SL1344ΔcrpΔasd,通过双酶切和PCR对质粒进行鉴定。结果表明,携带NDV HN基因片段的重组减毒鼠伤寒沙门氏菌SL1344ΔcrpΔasd(pYA3493-HN)构建成功。本研究结果为开发鸡新城疫的口服基因工程活载体疫苗奠定了基础。

Abstract: The study was aimed to construct prokaryotic expression vector of NDV HN gene using attenuated Salmonella typhimurium SL1344ΔcrpΔasd as a carrier. The HN gene was cloned from the plasmid pMD18-T-HN by polymerase chain reaction (PCR) and inserted into the vector pYA3493. Electricity transformation method was used in this recombinant plasmid pYA3493-HN transformating to recepted state Salmonella typhimurium SL1344ΔcrpΔasd. The recombinant plasmid pYA3493-HN was identified by digestion of endonuclease, PCR and sequencing. The results confirmed that recombinant attenuated Salmonella typhimurium vaccine SL1344ΔcrpΔasd(pYA3493-HN) was constructed successfully, which provided a foundation for research and development of NDV HN orally genetic engineering live vaccine.

Key words: Newcastle disease; HN gene; prokaryotic expression vector pYA3493; attenuated Salmonella typhimurium
