Twelve IBV isolants from diseased chickens in Maine were studied by serum-neutralization tests in chicken tracheal culture. Six isolants were neutralized by Mass-type antisera. The serum-neutralizing characteristics of six other isolants from vaccine breaks differed from any of the standard IBV viruses and appear to comprise three new strains, Maine 209, 212,and 246. The data provide additional evidence that strains of IBV responsible for disease probably vary from region to region and that the strains present must be known for a regional vaccination program to be effective.
通过在鸡气管培养物中进行血清中和试验，对缅因州患病鸡的12株传染性支气管炎病毒（IBV）分离株进行了研究。6株分离株被马萨诸塞型抗血清中和。另外6株来自疫苗接种失败病例的分离株的血清中和特性与任何标准IBV病毒都不同，似乎构成了三个新毒株，即缅因209、212和246。这些数据进一步证明，引起疾病的IBV毒株可能因地区而异，并且在制定有效的区域疫苗接种计划之前，必须了解当地存在的毒株。
