A survey for antibodies to West Nile virus (WNV; genus ,Flavivirus) was carried out by plaque-re-duction neutralization microtesting in 78 horses, 20 domestic chickens, and 97 wild birds belonging to 10 species from different areas in Poland. Specific antibodies were detected in five juvenile (hatching-year) birds collected in 2006: three white storks (Ciconia ciconia) in a wildlife rehabilitation center (5.4% of all examined storks; the antibody titers in each bird were 1:320, 1:160, and 1:20), one free-living mute swan (Cygnus olor; the titer was 1:20), and one hooded crow (Corvus corone cornix; the titer 1:20) in a wildlife rehabilitation center; thus the overall seropositivity to WNV was 5.2% among all the birds sampled. These data do not rule out the presence of WNV activity in Poland with 100% certainty, but they indicate a significant trace that demands verification. In addition, one black-headed gull (Larus ridibundus) had neutralizing antibodies for the Usutu Flavivirus, the first case recorded in Poland.
通过蚀斑减少中和微量试验，对来自波兰不同地区的78匹马、20只家鸡和属于10个物种的97只野生鸟类进行了西尼罗河病毒（WNV；黄病毒属）抗体检测。在2006年采集的5只幼鸟（当年孵化）中检测到特异性抗体：野生动物康复中心的3只白鹳（白鹳）（占所有检测鹳的5.4%；每只鸟的抗体滴度分别为1:320、1:160和1:20）、1只自由生活的疣鼻天鹅（疣鼻天鹅；滴度为1:20）和野生动物康复中心的1只秃鼻乌鸦（小嘴乌鸦；滴度为1:20）；因此，在所有采样鸟类中，对WNV的总体血清阳性率为5.2%。这些数据不能100%确定地排除波兰存在WNV活动的可能性，但它们表明了一个需要核实的重要线索。此外，1只黑头鸥（红嘴鸥）具有针对乌苏图黄病毒的中和抗体，这是波兰记录的首例。
