伪狂犬病防制策略及我国应采取的对策

伪狂犬病病毒（PRV）是α疱疹病毒属的一个成员，为伪狂犬病的病原，猪是伪狂犬病病毒的自然宿主，该病原一旦感染猪，则产生潜伏感染，其致死率随猪年龄的增加而降低。由于伪狂犬病的暴发引起畜牧业的巨大经济损失，许多国家都进行免疫接种预防该病，而该病在不同的国家地区危害不同，所造成的经济损失也不一样，另外各国的经济发展不平衡，因此对该病所采取的防制策略亦有所不同，文章综述了美国，日本，欧共体及其成员国之间对伪狂犬病采取的防制策略及取得的进展，并根据我国伪狂犬病的流行现状，提出了应采取的控制策略。

RESEARCH ADVANCES ON ERADICATION AND CONTROL PROGRAMMES AGAINST PSEUDORABIES AT HOME AND ABROAD

Pseudorabies virus(PRV),a member of the alphaherpesvirinae,is the causative agent of Aujeszky's disease.In pigs,the natural host of PRV,mortality decreases with increasing age,and upon primary infection a latent infection that can be reactivated is generally established.Since outbreaks of Aujesazky's disease cause important economics losses for livestock industry,many kinds of vaccines are widely used for vaccination of pigs and other animals.In the present paper,an overview is given about the pseudorabies eradication and control programs currently applies in the different countries or regions at abroad,together with the obtained results.According to the epidemic present status,the article points out the prophylactico therapeutic measures of pseudorabies taken in China.
