摘要
2013年以来,猪流行性腹泻(Porcine Epidemic Diarrhea,PED)疫情在美洲和亚洲的部分国家和地区暴发流行,对疫情发生国家或地区的生猪生产和猪肉市场供给造成极大影响。对全球PED疫情进行时间序列分析,发现PED流行范围逐步扩大,毒力不断增强,全球病毒基因序列相似,饲料特别是猪血液制品贸易可能是该病跨国界传播的潜在途径。
Since 2013,Porcine Epidemic Diarrhea(PED)occurred in some countries and regions of America and Asia,and caused serious impact on swine production and market pork supply in these countries and regions. This ar-ticle analyzes time series of global PED epidemic,and the results show that PED epidemic range is enlarging,PEDV virulence is increasing,gene-sequence of global PEDV strains are similar,and feed(especially pig blood products) trade is possibly potential way of trans-boundary transmission of PED.
