Abstract
In 2011, porcine epidemic diarrhea virus (PEDV) infection rates rose substantially in vaccinated swine herds. To determine the distribution profile of PEDV outbreak strains, we sequenced the full-length spike gene from samples from 9 farms where animals exhibited severe diarrhea and mortality rates were high. Three new PEDV variants were identified.
摘要
2011 年，猪流行性腹泻病毒（PEDV）在接种疫苗的猪群中的感染率大幅上升。为了确定 PEDV 爆发毒株的分布情况，我们对 9 个农场的样本进行了全长刺突基因测序，这些农场的动物表现出严重的腹泻和高死亡率。鉴定出了三种新的 PEDV 变体。
