摘要

本研究自美國愛荷華州內兩個火雞屠宰場，按照系統採樣的方式由7個火雞場共取得305個血樣，以血球凝集抑制試驗檢測新城雞瘟抗體並計算盛行率，7個火雞場中只有一場使用新城雞瘟疫苗免疫，該場之幾何平均抗體力價（以Log 2轉換後再取算術平均）是6.97。6場未免疫的火雞場中有2場出現陽性反應，以Log 2轉換後之幾何平均抗體力價分別為7.78及4.95，以上3個陽性火雞場之新城雞瘟血清抗體盛行率都是100%，剩下4 個陰性場之抽樣血清抗體力價全部低於1:8。本文並將說明感染新城雞瘟病毒的火雞與人類感染該病毒之關連。

Seven flocks of market turkeys were tested for hemagglutination-inhibiting (HI) antibodies against Newcastle disease virus (NDV). Systematic sampling of turkey blood samples (n=305) was done at two turkey packing plants located in the State of Iowa U.S.A. to determine the prevalence of NDV positive reactors. Only one of the seven flocks had been vaccinated against NDV. The geometric mean HI titer (log 2 transformation) for the vaccinated flock was 6.97. Two unvaccinated flocks were seropositive to NDV infections with geometric mean HI titers of 7.78 and 4.95. These 3 NDV positive flocks all had a seroprevalence rate of 100%. The remaining 4 unvaccinated flocks all had HI titers less than 1:8 which was interpreted as NDV free flocks. The implication for human infection from NDV-infected turkeys is stressed.
