Following the introduction of West Nile virus (WNV) into North America in 1999, surveillance for WNV in migratory and resident birds was established in Tamaulipas State, northern México in December 2001. Overall, 796 birds representing 70 species and 10 orders were captured and assayed for antibodies to WNV. Nine birds had flavivirus-specific antibodies by epitope-blocking enzyme-linked immunosorbent assay; four were confirmed to have antibody to WNV by plaque reduction neutralization test. The WNV-infected birds were a house wren, mourning dove, verdin and Bewick's wren. The house wren is a migratory species; the other WNV-infected birds are presumably residents. The WNV-infected birds were all captured in March 2003. These data provide the first indirect evidence of WNV transmission among birds in northern México.
1999年西尼罗河病毒（WNV）传入北美后，2001年12月在墨西哥北部的塔毛利帕斯州建立了对候鸟和留鸟的WNV监测。总体而言，捕获了代表70个物种和10个目的796只鸟，并检测了它们针对WNV的抗体。通过表位阻断酶联免疫吸附试验，有9只鸟具有黄病毒特异性抗体；通过蚀斑减少中和试验，4只鸟被确认为具有WNV抗体。感染WNV的鸟类有一只家鹪鹩、一只哀鸽、一只棕煌蜂鸟和一只比威克氏鹪鹩。家鹪鹩是候鸟；其他感染WNV的鸟类据推测是留鸟。所有感染WNV的鸟类均于2003年3月捕获。这些数据提供了墨西哥北部鸟类之间WNV传播的首个间接证据。
