摘要
2010年底至今,华南地区暴发了严重的高死亡率猪流行性腹泻病(PED),为了解该地区发病猪场PEDV的感染情况,应用PED胶体金检测试剂盒和RT-PCR检测方法测定了不同地区60家发病猪场的粪便样品。结果显示,60个猪场中,PEDV阳性率为100%,不同规模猪场平均死亡率为76.87%;该病一年四季均可发生,但冬春季节高发;采取免疫组织灭活苗和返饲方法在一定程度上能够有效控制PED的发生和流行。
Since the end of 2010, porcine epidemic diarrhea （PED） outbreak in south China, characterized by high mortality rates. In order to get the information of porcine epidemic diarrhea virus （PEDV）infection in this region, we tested fecal samples from 60 farms by PED detection kit and RT-PCR assay. The results showed that all the farms had PEDV positive and average mortality rate was 76.87% in different farms; PED could occur year round, but it was high incidence in winter and spring; Inactivated vaccine immunization and back feeding method could effectively control the incidence and prevalence of porcine epidemic diarrhea disease in the certain extent.
