This study was designed to explore the role that red-winged blackbirds (Agelaius phoeniceus) may have played in disseminating West Nile virus (WNV) across the United States. Using enzyme-linked immunosorbent assays designed to detect WNV antibodies in avian species we were able to determine the WNV antibody prevalence in a cohort of red-winged blackbirds in central North Dakota in 2003 and 2004. The peak WNV antibody prevalence was 22.0% in August of 2003 and 18.3% in July of 2004. The results of this study suggest that red-winged blackbird migratory populations may be an important viral dispersal mechanism with the ability to spread arboviruses such as WNV across the United States.
本研究旨在探究红翅黑鹂(Agelaius phoeniceus)在美国传播西尼罗河病毒(WNV)过程中可能扮演的角色。通过使用旨在检测鸟类物种中WNV抗体的酶联免疫吸附测定法,我们得以确定2003年和2004年北达科他州中部一群红翅黑鹂的WNV抗体流行率。WNV抗体流行率峰值在2003年8月为22.0%,在2004年7月为18.3%。本研究结果表明,红翅黑鹂迁徙种群可能是一种重要的病毒传播机制,有能力在美国传播诸如WNV等虫媒病毒。
