Egypt has experienced outbreaks of avian influenza (AI) since 2006. A total of 3583 cloacal swabs were collected from chickens, ducks, geese and turkeys from commercial farms, backyards and local bird markets in Qena and Luxor governorates in South Egypt during 2009-2011. These samples were examined for the presence of AI virus (AIV) and positive samples were further subtyped for the H5 and H9 by real time RT-PCR. In this way, 202 (5.64%) samples were found to be AIV-positive of which 186 (92.08%) and 7 (3.46%) belonged to H5 and H9 subtypes, respectively. Higher infection rates were observed in backyard birds and birds from local bird markets in comparison to birds from commercial farms. In conclusion, the predominance of H5 infection indicates a need for continuous monitoring of AIV among avian species and the awareness against public health risk.
自2006年以来，埃及经历了禽流感（AI）疫情。2009年至2011年期间，从埃及南部基纳省和卢克索省的商业农场、后院及当地鸟类市场的鸡、鸭、鹅和火鸡中总共采集了3583份泄殖腔拭子。对这些样本进行禽流感病毒（AIV）检测，阳性样本通过实时逆转录聚合酶链反应进一步进行H5和H9亚型分型。通过这种方式，发现202份（5.64%）样本为AIV阳性，其中186份（92.08%）和7份（3.46%）分别属于H5和H9亚型。与商业农场的禽类相比，后院禽类和当地鸟类市场的禽类感染率更高。总之，H5感染的优势表明需要持续监测禽类中的AIV，并提高对公共卫生风险的认识。
