在埃塞俄比亚Debre Zeit的埃塞俄比亚农业研究所（EIAR）经营的一个养鸡场进行了一项家禽呼吸道传染病调查。从117只随机选择的鸡中采集口咽拭子，并从其中73只鸡的子集中采集血液。采用血清学和分子生物学相结合的方法进行病原体检测。在埃塞俄比亚首次发现鸡传染性支气管炎病毒变异株（793 B基因型）、禽偏肺病毒B亚型和滑液支原体。还发现存在鸡毒支原体;然而，通过PCR未检出传染性喉气管炎病毒。PCR未检测到纽卡斯尔病病毒（NDV），但抗NDV HI抗体滴度的变化水平表明可能暴露于强毒株或疫苗接种不良，或两者兼而有之。对于埃塞俄比亚新兴的密集型产业，这项研究强调了几种可能影响家禽福利和生产力的传染性呼吸道病原体。
A survey was conducted into respiratory infectious diseases of poultry on a chicken breeder farm run by the Ethiopian Institute of Agricultural Research (EIAR), located in Debre Zeit, Ethiopia. Oropharyngeal swabs were collected from 117 randomly selected birds, and blood was taken from a subset of 73 of these birds. A combination of serological and molecular methods was used for detection of pathogens. For the first time in Ethiopia, we report the detection of variant infectious bronchitis virus (793B genotype), avian metapneumovirus subtype B and Mycoplasma synoviae in poultry. Mycoplasma gallisepticum was also found to be present; however, infectious laryngotracheitis virus was not detected by PCR. Newcastle disease virus (NDV) was not detected by PCR, but variable levels of anti-NDV HI antibody titres shows possible exposure to virulent strains or poor vaccine take, or both. For the burgeoning-intensive industry in Ethiopia, this study highlights several circulating infectious respiratory pathogens that can impact on poultry welfare and productivity.
