摘要
猪流行性腹泻(Porcine Epidemic Diarrhea,PED)是一种由猪流行性腹泻病毒(PorcineEpidemicDiarrheaVirus,PEDV)引起的一种急性接触性肠道传染病。该病毒主要通过粪-口途径传播,猪感染后会引起严重的腹泻、呕吐和脱水,致死率极高,可达100%。即使有仔猪能够侥幸存活,相比健康仔猪,幸存仔猪的日增重等生长性能远远达不到生猪养殖生产指标,只能淘汰处理,给养猪业造成了巨大的经济损失。自20世纪80年代初在欧洲首次发现以来,猪流行性腹泻已经成为全球猪业面临的重要问题之一。该文旨在综述猪流行性腹泻的病原特征、流行特征、致病机制、疫苗研发等方面进行综述,以期为养猪业提供参考。
Porcine Epidemic Diarrhea(PED)is an acute contact intestinal infectious disease caused by Porcine Epidemic Diarrhea Virus(PEDV)in pigs.The virus is mainly transmitted through fecal oral routes,and infected pigs can cause severe diarrhea,vomiting,and dehydration,with a high mortality rate of up to 100%.Even if there are piglets that can survive with luck,compared to healthy piglets,the daily weight gain and other growth performance of surviving piglets are far from meeting the production indicators of live pig farming,and can only be eliminated,causing huge economic losses to the pig farming industry.Since itsfirst discovery in Europe in the early 1980s,PED has become one of the important issues facing the global pig industry.This article aims to review the pathogenic characteristics,epidemic characteristics,pathogenic mechanisms,vaccine development,and other aspects of porcine epidemic diarrhea,in order to provide reference for the pig industry.
