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.
從明尼蘇達州南部和愛荷華州北部的六個豬場提取的動物樣品和環(huán)境樣品中檢測出三種孤立的甲型流感病毒(IAV)菌株，研究人員懷疑那邊有流感爆發(fā)。根據(jù)公共科學圖書館期刊(PLoS One)的研究，由于被確診區(qū)域的農場獸醫(yī)約摸感染流感，美國研究者從農場提取唾液、豬圈及室內空氣樣本。有五個人被確診感染甲型流感病毒(IAV)，其中有48%的唾液樣本，38%的豬圈樣本和43%的室內空氣樣本通過聚合酶鏈反應檢測出含有甲型流感病毒。
