Infectious bursal disease virus (IBDV) is an immunosuppressive pathogen of poultry causing great economic losses to the poultry industry. In this study, the IBDV antibodies were detected in captured free-living wild birds in Zaria, Nigeria. One hundred and fifty free-living wild birds, comprising 30 birds each of 5 different species, were sampled over a period of 9 months. Blood samples were collected from each bird, and harvested sera were tested for IBDV antibodies using enzyme-linked immunosorbent assay. Results indicated IBDV seroprevalences in speckled pigeon (6.67%) and cattle egret (3.33%). In conclusion, the detection of IBDV antibodies in free-living wild birds in this study is indicative of previous natural exposure of these birds to the virus. These species of wild birds could therefore serve as carriers of these viruses and, consequently, transmit these viruses to chickens.
传染性囊病病毒（IBDV）是一种禽类免疫抑制性病原体，给家禽养殖业造成了巨大的经济损失。本研究在尼日利亚扎里亚捕获的自由生活野生鸟类中检测到了 IBDV 抗体。在 9 个月的时间里，采集了 150 只自由生活的野生鸟类，每个物种 30 只。从每只鸟身上采集血液样本，并使用酶联免疫吸附试验检测收获的血清中的 IBDV 抗体。结果表明，点斑鸽（6.67%）和牛背鹭（3.33%）存在 IBDV 血清阳性。总之，本研究中在自由生活的野生鸟类中检测到 IBDV 抗体表明这些鸟类之前曾自然感染过该病毒。这些野生鸟类因此可能成为这些病毒的携带者，并将这些病毒传播给鸡。
