禽流感爆发已导致数百万计家禽和猪死亡或被扑杀，给农民和生产者造成了数百万美元的损失。禽流感也是影响人类的致命疾病。特别的关注点是能够在疾病爆发之前识别病原体的技术。就禽流感而言，鸟类的羽毛、爪或喙的稳定同位素组成揭示迁徙鸟类开始旅程的地方。分子技术可以检测受感染鸟的粪便中是否存在禽流感等病毒，并可以查明受感染的鸟的种类。结合通过这些技术收集的信息，研究人员可以跟踪鸟类的迁徙，确定它们来自哪里，飞行的路径，以及哪些种类携带着病毒。这使得兽医服务在预测较高爆发风险地点方面先行一步。 http://www-naweb.iaea.org/nafa/resources-nafa/Avian-Influenza-LR.mp4 Subscribe! http://www.youtube.com/subscription_center?add_user=FAOoftheUN Follow #UNFAO on social media! * Facebook - https://www.facebook.com/UNFAO * Google+ - https://plus.google.com/+UNFAO * Instagram - https://instagram.com/unfao/ * LinkedIn - https://www.linkedin.com/company/fao * Twitter - http://www.twitter.com/faoknowledge © FAO: http://www.fao.org
