猪流感病毒血凝素基因的研究进展

猪流感是由猪流感病毒引起的一种急性、热性、高度接触传染性呼吸道疾病，可继发和并发多种细菌病和病毒病，已日益成为危害世界猪群的主要传染病之一。猪流感病毒血凝素基因作为流感病毒表面最主要的抗原基因，其表达蛋白具有丰富的生物学作用，对流感病毒的致病性起着主导作用。作者主要对猪流感病毒血凝素基因的研究进行了综述，为进一步防治猪流感及开发新型疫苗提供帮助。

Progress on Hemagglutinin Gene Research of Swine Influenza Virus

Swine influenza, which is an acute, hermotropic, highly infectious viral respiratory disease of pigs, is caused by swine influenza virus. It can produce different kinds of bacterial or viral disease which is secondary and concurrency, so it is becoming one of the most hazardous dieases in the livestock husbandry gradually. The hemagglutinin gene, main antigen of swine influenza virus on the surface, is of crucial importance to the pathogenic of SIV, and the hemagglutinin protein also has rich biological effects. The research of swine influenza virus hemagglutinin gene will provide help to prevent swine influenza and offer ideas to develop new typies of vaccines.
