Forty-four haemagglutinating viruses were isolated from the pooled tracheal/cloacal swabs of the dead birds from 170 consignments of caged birds arriving at Heathrow Airport over a period of 6 months. Two isolates were identified as Newcastle disease virus but the remaining 42 were all identified as influenza viruses with Hav 7 Neq 2 antigens. All the consignments from which influenza viruses were isolated originated in India but had widespread destinations. The NDV isolates were from birds originating in central America and destined for Japan.
在6个月的时间里,从抵达希思罗机场的170批笼养鸟的死鸟气管/泄殖腔拭子混合样本中分离出44种血凝病毒。其中两株被鉴定为新城疫病毒,其余42株均被鉴定为具有Hav 7 Neq 2抗原的流感病毒。所有分离出流感病毒的批次均原产于印度,但目的地广泛。新城疫病毒分离株来自原产于中美洲、目的地为日本的鸟类。
