| 中文摘要: |
| 猪伪狂犬病是一种由伪狂犬病病毒（Pseudorabies virus，PRV）感染引起的急性高度接触性传染病，可造成不同日龄的猪发病，给养猪业造成了严重的经济损失。预防、控制甚至消灭猪伪狂犬病的主要措施之一是疫苗免疫接种。通过基因重组技术对 PRV 关键毒力基因进行改造，敲除毒力基因或插入免疫增强基因，是降低 PRV 毒力或提高病毒免疫保护效果的有效方法之一，也是研制安全高效 PRV 基因工程疫苗的重要手段。从基因同源重组、Cre/lox P 位点特异性重组、细菌人工染色体和 CRISPR 基因编辑等不同基因重组技术应用方面对猪PRV 基因工程疫苗的研制进行综述，为 PRV 重组疫苗的进一步深入研究提供参考。 |
| 英文摘要: |
| Porcine pseudorabies is an acute and highly contagious disease caused by pseudorabies virus (PRV) infection, which can cause disease in pigs of different ages and serious economic losses to the pig industry. One of the main measures to prevent, control and even eradicate porcine pseudorabies is vaccination. It is one of the effective methods to reduce the virulence of PRV or improve the immune protection effect of virus by transforming the key virulence genes of PRV, knocking out the virulence genes or inserting the immune enhancement genes through gene recombination technology,
and it is also an important means to develop a safe and efficient genetic engineering vaccine of PRV. The development of porcine PRV genetic engineering vaccine was reviewed from the application of different gene recombination technologies, such as homologous recombination, Cre/loxP site-specific recombination, bacterial artificial chromosome and CRISPR gene editing, with a view to provide references for further study of PRV recombinant vaccine. |
