纽卡斯尔病（ND）和传染性支气管炎（IB）是影响鸟类呼吸道的两种主要病毒性疾病，其对非洲家禽的影响仍然知之甚少。在本研究中，我们旨在通过巢式PCR对22，000份禽拭子进行分子筛选，并通过2010年至2012年对近2000份禽血清进行血清学检测，评估象牙海岸的NDV和IBV流行情况。在研究期间，NDV和IBV血清阳性率分别达到22%和72%。我们发现14.7%的混合拭子PCR阳性NDV和14.6%的IBV。因此，这两种病原体都是象牙海岸的地方病。与NDV和IBV感染相关的经济损失仍需评估。家禽饲养场禽流感病毒监察呈阴性反应。研究将纽卡斯尔病和传染性支气管炎作为鉴别诊断疾病，纽卡斯尔病病毒血清阳性率远低于传染性支气管炎病毒。对传染性支气管炎的第一次研究表明，散养家禽的发病率很高。这两种病原体都是地方性的，造成经济损失，需要进行全面评估。
Newcastle disease (ND) and infectious bronchitis (IB) are two major viral diseases affecting the respiratory tracts of birds and whose impact on African poultry is still poorly known. In the present study we aimed at assessing NDV and IBV prevalences in Ivory-Coast by molecular screening of > 22,000 avian swabs by nested PCR and by serology testing of close to 2000 avian sera from 2010 through 2012. The NDV and IBV seroprevalences over the study period reached 22% and 72%, respectively. We found 14.7% pooled swabs positive by PCR for NDV and 14.6% for IBV. Both pathogens are therefore endemic in Ivory-Coast. Economic losses associated with NDV and IBV infections still need to be evaluated. Surveillance of avian influenza virus is found negative in backyard poultry farm. Study of Newcastle disease and infectious bronchitis as differential diagnosis diseases Newcastle disease virus seroprevalence is much lower than infectious bronchitis virus. First study of infectious bronchitis revealed high prevalence in backyard poultry. Both pathogens are endemic, cause economic losses and need to be fully evaluated.
