　　US - Three separate strains of influenza A virus (IAV) have been detected in animal and environmental samples taken from six swine farms in southern Minnesota and northern Iowa with suspected flu outbreaks.According to the study in PLoS One, US researchers took oral fluid, pen railing, and indoor air samples from farms that were identified by area veterinarians as likely hit by flu.Five of the outbreaks were confirmed to be caused by IAV. Of those, 48 per cent (47/98) of oral fluid, 38 per cent (32/84) of pen railing, and 43 per cent (35/82) of indoor air samples tested positive for influenza A by polymerase chain reaction.

　　从明尼苏达州南部和爱荷华州北部的六个猪场提取的动物样品和环境样品中检测出三种孤立的甲型流感病毒(IAV)菌株，研究人员怀疑那边有流感爆发。根据公共科学图书馆期刊(PLoS One)的研究，由于被确诊区域的农场兽医约摸感染流感，美国研究者从农场提取唾液、猪圈及室内空气样本。有五个人被确诊感染甲型流感病毒(IAV)，其中有48%的唾液样本，38%的猪圈样本和43%的室内空气样本通过聚合酶链反应检测出含有甲型流感病毒。
