Abstract

Wild birds have been reported to be reservoirs of viral diseases of poultry, and play an epidemiological role in their maintenance and spread. A serological survey was undertaken to determine the evidence of Newcastle disease virus (NDV) antibodies in wild birds in Zaria Kaduna State, Nigeria. A total of 150 apparently healthy wild birds comprising 30 each laughing dove, speckled pigeons, cattle egrets, village weavers and African silver bills were sampled. Sera collected were analysed for the presence of antibodies against NDV and avian paramyxovirus‑2 (APMV‑2) using the haemagglutination inhibition test. The results showed an overall seroprevalence of 4% (95% CI: 2.05‑10.1) to NDV. African silver bill showed a seroprevalence of 10.0% (95% CI: 2.61‑24.9) NDV antibodies while seroprevalence of 3.3% (95% CI: 0.16‑15.4) was recorded for cattle egrets, village weavers and laughing doves respectively. No statistically significant difference existed for NDV seroprevalence (P>0.05) among the different species of wild birds. All the 150 sera tested negative for APMV‑2 antibodies. The result of this study confirmed the exposure of wild birds to NDV in the study area. Continuous surveillance with isolation and characterization of NDV in the wild birds is therefore recommended for strategic planning for control.

尼日利亚卡杜纳州扎里亚野生鸟类新城疫病毒抗体的血清学证据。

据报道，野生鸟类是家禽病毒性疾病的储库，在疾病的维持和传播中发挥着流行病学的作用。为了确定尼日利亚扎里亚-卡杜纳州野鸟体内新城疫病毒（NDV）抗体的证据，我们开展了一项血清学调查。共对 150 只表面健康的野生鸟类进行了采样，其中包括笑鸽、斑鸠、牛鹭、乡村织女和非洲银嘴鸦各 30 只。采用血凝抑制试验对采集的血清进行分析，以检测是否存在 NDV 和禽副粘病毒-2（APMV-2）抗体。结果显示，NDV 的总体血清流行率为 4%（95% CI：2.05-10.1）。非洲银嘴鸥的 NDV 抗体血清流行率为 10.0%（95% CI：2.61-24.9），而牛鹭、村织鸽和笑鸽的 NDV 抗体血清流行率分别为 3.3%（95% CI：0.16-15.4）。不同种类野生鸟类的 NDV 血清流行率在统计学上无明显差异（P>0.05）。所有 150 份血清的 APMV-2 抗体检测结果均为阴性。这项研究结果证实，研究地区的野生鸟类接触过 NDV。因此，建议对野生鸟类中的 NDV 进行分离和特征描述，并进行持续监测，以制定战略控制计划。

期刊介绍： The journal was created as the Croce Azzurra in 1950. A quarterly peer-reviewed journal devoted to veterinary public health and other aspects of veterinary science and medicine, Veterinaria Italiana is published by the Istituto Zooprofilattico Sperimentale dell’Abruzzo e del Molise ‘G. Caporale’ (Istituto Zooprofilattico Sperimentale dell''Abruzzo e del Molise) in Teramo, Italy. The goal of the journal is to provide an international platform for veterinary public health information from Italy and other countries, particularly those in Eastern Europe and Africa, Asia and South America. Veterinarians and veterinary public health specialists are encouraged to share their knowledge and experience on this platform.
