West Nile virus (WNV) causes a mosquito-borne zoonotic disease of public health importance. The aim of this study was to determine the state of WNV infection in horses and detect the virus antigen in mosquitoes trapped in stables in Kaduna State Nigeria. The study was carried out in Kaduna State, Nigeria, and 368 horses were screened for the presence of antibodies against WNV using an IgG competitive enzyme-linked immunosorbent assay. Of the 368 samples tested, 331 (89.9%) were positive for WNV antibodies. Mosquitoes from the stables were tested for WNV antigen using a VectorTest kit, and of the 31 pools of adult mosquitoes tested, only 5 (16.1%) pools tested positive for WNV antigen. This finding showed that WNV infection has occurred in horses and that there is evidence of circulation of the virus by mosquitoes in Kaduna State, Nigeria.
西尼罗河病毒（WNV）引发一种具有公共卫生重要性的蚊媒人畜共患病。本研究的目的是确定尼日利亚卡杜纳州马匹的西尼罗河病毒感染状况，并检测在马厩中捕获的蚊子体内的病毒抗原。该研究在尼日利亚卡杜纳州开展，使用IgG竞争性酶联免疫吸附测定法对368匹马进行了西尼罗河病毒抗体检测。在检测的368份样本中，331份（89.9%）西尼罗河病毒抗体呈阳性。使用VectorTest试剂盒对来自马厩的蚊子进行西尼罗河病毒抗原检测，在检测的31组成年蚊子样本中，只有5组（16.1%）西尼罗河病毒抗原检测呈阳性。这一发现表明，尼日利亚卡杜纳州的马匹已发生西尼罗河病毒感染，且有证据表明该病毒通过蚊子在当地传播。
