In infectious bronchitis (IB) virus infection of the chicken the upper and lower respiratory tracts were damaged, but infectious laryngotracheitis (ILT) virus caused lesions only in the upper respiratory tract. Secondary infection with Escherichia coli was apparent in the trachea of birds inoculated with either virus but was more striking in those given IB virus. Serum alpha 1-acid glycoprotein, an acute-phase protein, occurred in higher concentrations in chickens inoculated with IB virus than in those given ILT virus.
在鸡的传染性支气管炎（IB）病毒感染中，上、下呼吸道均受到损害，但传染性喉气管炎（ILT）病毒仅在上呼吸道引起病变。接种任一病毒的鸡的气管中均明显存在大肠杆菌继发感染，但在接种IB病毒的鸡中更为显著。血清α1-酸性糖蛋白作为一种急性期蛋白，在接种IB病毒的鸡中的浓度高于接种ILT病毒的鸡。
