An outbreak of porcine epidemic diarrhea virus (PEDV) in the South of Portugal in January 2015 and the spread of PEDV northwards in the territory are described. Comparative analysis of the amplified sequences showed a very high (99.0%) identity with the PEDV variant most recently reported in the United States and also show complete (100%) identity to the strains recently reported in Germany, supporting the hypothesis that a unique strain is currently circulating in Europe. The origin of this PEDV variant still needs to be elucidated and further studies in the remaining European countries may contribute to the knowledge.
描述了2015年1月在葡萄牙南部爆发的猪流行性腹泻病毒（PEDV）疫情以及该病毒在该国境内向北传播的情况。对扩增序列的比较分析表明，其与美国最近报道的PEDV变体具有非常高的（99.0%）同源性，并且与德国最近报道的毒株也具有完全（100%）同源性，这支持了目前在欧洲流行的是单一毒株这一假设。这种PEDV变体的起源仍有待阐明，在欧洲其他国家开展的进一步研究可能会有助于了解这方面的情况。
