摘要
１９９６年９月份以来，青岛地区鸡群发生一种新病，通过鸡胚盲传５代—６代，电镜观察、动物回归和免疫保护试验、用气管环组织培养进行理化特性测定、毒价测定、中和试验，证明目前流行的以腺胃肿大为主要特征的传染病的病原是冠状病毒，因为引起腺胃的特征性的病理变化，将此病暂定名为腺胃型传染性支管炎，将青岛分离株定为ＱＸ株。
Outbreaks of a new disease occurred in chicken flocks in Qingdao areas since September 1996.Coronavirus was found to be the causative agent of the disease characterized mainly by glandular stomach swelling, based on 56 blind passages in chicken embryoes, electron microscope examination, animal regression and immune protection experiment,TOC culture and neutralization test. The disease was temporarily termed as glandular stomach type infectious bronchitis due to the characteristic lesions in the glandular stomach of the infected chickens and the isolate got in Qingdao area was designated as QX IBV.An oiladjuvant inactivated vaccine prepared from QX IBV yielded a protection rate of over 95% in field trials.
