摘要: 猪流行性腹泻(Porcine epidemic diarrhea,PED)是一种由猪流行性腹泻病毒(Porcine epidemic diarrhea virus,PEDV)引起的一种猪急性、高度接触性的肠道传染病,由于其高发病率和高致死率,给全球养猪业造成了巨大的经济损失。接种疫苗是当前预防PED最经济和有效的措施,但由于PEDV变异株的不断出现,疫苗的免疫保护效果不佳。因此,急需研发更加安全、高效的疫苗来预防PED。综述了PEDV的病原学特性、致病机制以及PEDV疫苗研究的最新进展,并对PEDV新型高效疫苗的研究策略进行展望,以期为临床上有效防控PED提供参考。

Abstract: Porcine epidemic diarrhea(PED)caused by porcine epidemic diarrhea virus(PEDV)is an acute and highly contagious enteric disease of pigs,which leads to high morbidity and mortality in the suckling piglets,thereby bringing huge economic losses to the global pig industry.Vaccination is currently the most economical and effective measure for the prevention of PED,but due to the continuous emergence of PEDV variants,the immune protection of the vaccine is not effective.Therefore,the development of safer and more effective vaccines for preventing PED is urgently needed. Here we mainly reviewed the pathogenic characteristics,the pathogenic mechanism of PEDV,and the latest progress in PEDV vaccine research. Futhermore,the research strategy of a novel and effective PEDV vaccine was also prospected,to provide a reference for effective prevention and control of PED in clinical settings.
