An outbreak of severe respiratory disease in flocks of broiler chickens was associated with the isolation of a 'novel' strain of infectious bronchitis virus (IBV). The isolate, designated 624/I, was isolated from 9 of the 11 flocks sampled. The results of cross neutralisation and haemagglutination-inhibition tests showed isolate 624/I to be antigenically distinct from several European and American strains. In a serological survey carried out on affected flocks, specific antibodies to IBV strain 624/I and turkey rhinotracheitis (TRT) virus were detected.
肉鸡群中爆发的严重呼吸道疾病与一种“新型”传染性支气管炎病毒（IBV）毒株的分离有关。该毒株被命名为624/I，是从所采集的11个鸡群中的9个鸡群中分离出来的。交叉中和试验和血凝抑制试验结果表明，624/I毒株在抗原性上与几种欧美毒株不同。在对受影响鸡群进行的血清学调查中，检测到了针对IBV 624/I毒株和火鸡鼻气管炎（TRT）病毒的特异性抗体。
