Widespread deaths of American Crows (Corvus brachyrhynchos)were associated with the 1999 outbreak of West Nile (WN) virus in the New York City region. We compared six organs from 20 crow carcasses as targets for WN virus detection. Half the carcasses had at least one positive test result for WN virus infection. The brain was the most sensitive test organ; it was the only positive organ for three of the positive crows. The sensitivity of crow organs as targets for WN virus detection makes crow death useful for WN virus surveillance.
美国乌鸦(短嘴鸦)的大量死亡与1999年纽约市地区西尼罗河(WN)病毒的爆发有关。我们比较了20只乌鸦尸体的六个器官,作为检测WN病毒的目标。一半的尸体对WN病毒感染至少有一项阳性检测结果。大脑是最敏感的检测器官;它是三只阳性乌鸦唯一呈阳性的器官。乌鸦器官作为WN病毒检测目标的敏感性使得乌鸦死亡对WN病毒监测很有用。
