The antigenic relationships between 17 Australian infectious bronchitis viruses, including six vaccine viruses, were studied by a neutralisation test using a plaque reduction method in chick embryo kidney cell monolayers. The 17 viruses formed nine distinct subtypes. Antiserum to each subtype had a high titre to viruses of the same subtype and a lower titre to viruses of different subtypes. The heterologous titres of sera varied widely.
采用蚀斑减少法,在鸡胚肾细胞单层上进行中和试验,研究了17株澳大利亚传染性支气管炎病毒(包括6株疫苗病毒)之间的抗原关系。这17株病毒形成了9个不同的亚型。针对每个亚型的抗血清对同一亚型的病毒具有高滴度,而对不同亚型的病毒具有较低滴度。血清的异源滴度差异很大。
