用血凝抑制法对1986年分离的3株传染性支气管炎病毒分离株进行了血清学分型，发现它们与美国目前用于常规和特别许可疫苗的7株毒株(MASS 41、H52、H120、Conn 46、Fla 18288、JMK和Ark 99)以及其他13株参考毒株的血清学不同。最近的分离株来自蛋鸡群，它们有过鸡蛋产量下降和蛋壳质量问题的历史。其中两个分离株，分别来自缅因州和俄亥俄州，在血清学上与1983年来自美国宾夕法尼亚州蛋鸡替代品的IBV分离株有关。来自韩国的第三个分离株在血清学上不同于任何参考菌株和其他新分离株。
Three 1986 infectious bronchitis virus (IBV) isolates were serotyped by a hemagglutination-inhibition method and were found to be serologically different from the seven strains currently used in regular and specially licensed vaccines in the United States (Mass 41, H52, H120, Conn 46, Fla 18288, JMK, and Ark 99) and from 13 other reference IBV strains. The recent isolates were from layer flocks that had histories of egg production declines and shell-quality problems. Two of the isolates, one each from Maine and Ohio, were serologically related to a 1983 IBV isolate from layer replacements in Pennsylvania [USA). The third isolate from Korea, was serologically different from any of the reference strains and the other new isolates.
