摘要
猪繁殖与呼吸综合征病毒,引起猪繁殖与呼吸综合征,俗称"猪蓝耳病",是目前持续危害我国养猪业的病原之一。该病毒毒株极具多样性,1995年进入我国后,基因组和致病力不断进化,2006年高致病力毒株引起猪繁殖与呼吸综合征疫情大暴发,造成巨大损失,疫情平息后仍呈地方性流行,时至今日,中低毒力毒株引起的免疫抑制以及高毒力毒株引起的猪只死亡,已是我国猪场面临的巨大难题。对猪繁殖与呼吸综合征病毒在我国的流行与进化进行归纳综述,旨在通过探讨病毒的流行规律,为生产中猪繁殖与呼吸综合征的预防与控制提供参考。
Porcine reproductive and respiratory syndrome virus (PRRSV), causes porcine reproductive and respiratory syndrome, commonly known as "Blue ear disease", is one of the continuously harmful pathogens of swine industry in China. PRRSV diverse greatly between different prototypes. After intruding into China in 1995, the genome and pathogenicity of PRRSV kept evolving and resulted in the "high pathogenic PRRSV" outbreak, which happened in 2006 and cause huge lose. PRRS remained endemic after the outbreak, andtill now, immune suppression caused by the lower virulent PRRSV strains and mortality caused by the higher virulent PRRSV strains have become a great challenge to the pig farms of China. Through discussing the epidemic rules of PRRSV, prevalence and evolution of PRRSV in China were summarized, to provide reference for prevention and control of PRRS in pig production.
