The objective of this study was to determine evidence of previous West Nile virus (WNV) infection in northern California owls. Owl serum samples were collected from birds presenting to a veterinary medical teaching hospital between 2007 and 2014 and were screened for the presence of WNV antibodies by an indirect enzyme immunoassay (EIA). Only one of 71 samples (1.41%) tested was positive by EIA and confirmed by a plaque reduction neutralization test; it was the most recent sample collected. The reason for the low prevalence of WNV in these California owls despite a high prevalence in sympatric avian species in the same region is unknown and should be a topic for further research.
本研究的目的是确定北加利福尼亚猫头鹰先前感染西尼罗河病毒（WNV）的证据。从2007年至2014年就诊于一家兽医医学教学医院的鸟类中采集猫头鹰血清样本，并通过间接酶免疫测定法（EIA）筛查WNV抗体的存在。在检测的71个样本中，只有1个（1.41%）通过EIA检测呈阳性，并经蚀斑减少中和试验确认；它是采集的最新样本。尽管在同一地区的同域鸟类中WNV流行率很高，但这些加利福尼亚猫头鹰中WNV流行率低的原因尚不清楚，应作为进一步研究的课题。
