An infectious-bronchitis-like virus was isolated from 6-week-old broiler chickens unvaccinated with infectious bronchitis virus (IBV). The isolate produced lesions in embryonating chicken eggs (ECE) and clinical signs in birds characteristic of IBV. Serum-neutralization and agar-gel diffusion tests demonstrated the serological relationship of this isolate to IBV.
从6周龄未接种传染性支气管炎病毒（IBV）的肉鸡中分离出一种类似传染性支气管炎的病毒。该分离株在鸡胚（ECE）中产生病变，并在禽类中引起具有IBV特征的临床症状。血清中和试验和琼脂凝胶扩散试验证明了该分离株与IBV的血清学关系。
