Abstract

Two swine influenza (SI) H1N1 virus was isolated from a pig during a severe outbreak of respiratory disease in south China. The two H1N1 influenza viruses were classical SI virus. A/swine/Guangdong/L6/09 is classical SI virus of recent years, which is of the main SI virus in China. Howere, A/swine/Guangdong/L3/09 was closet to A/swine/Iowa/1931, which was the first isolated SI virus and had demonstrated significant pathogenicity in animal models. The results of phylogenetic analysis of A/swine/Guangdong/L3/09 showed a close relationship with the 1918 pandemic virus. The results suggested that the previous SI virus appeared again. Whether, it brought a new pandemic to pigs deserves more attention.

摘要

在中国南方一场严重的呼吸道疾病暴发期间,从一头猪身上分离出两株甲型H1N1猪流感(SI)病毒。这两株H1N1流感病毒均为经典猪流感病毒。A/猪/广东/L6/09是近年来的经典猪流感病毒,是中国主要的猪流感病毒之一。然而,A/猪/广东/L3/09与A/猪/爱荷华/1931最为接近,后者是最早分离出的猪流感病毒,且已在动物模型中显示出显著的致病性。对A/猪/广东/L3/09的系统发育分析结果显示,它与1918年大流行病毒关系密切。结果表明,先前的猪流感病毒再次出现。它是否会给猪带来新的大流行值得更多关注。
