Fifteen british field strains of IBV were compared using cross serum neutralization tests in embryonated eggs with seven standard reference strains of IBV. While the British field strains were considered to form a relatively homogeneous group considerable antigenic variation did occur. It was considered that it was not feasible at this time to describe accurately a serotype classification for IBV, similar to that described for other virus groups.
使用鸡胚中的交叉血清中和试验,将15株英国传染性支气管炎病毒(IBV)野毒株与7株IBV标准参考毒株进行了比较。虽然英国野毒株被认为形成了一个相对同质的群体,但确实出现了相当大的抗原变异。目前认为,准确描述IBV的血清型分类是不可行的,这与其他病毒组的描述不同。
