Pasteurella haemolytica was isolated from internal organs of laying hens and pullets of four flocks in which five incidents of increased mortality had occurred. There was inflammation of the trachea in all cases, and infectious laryngotracheitis virus was identified in three of the incidents. Rapid response to antimicrobial therapy was seen in two out of three outbreaks in the pullets. P. haemolytica was regarded as a significant secondary invader in these cases.
从四个鸡群的产蛋母鸡和小母鸡的内脏中分离出溶血巴斯德氏菌，这些鸡群发生了五起死亡率增加的事件。所有病例均有气管炎症，其中三起事件中鉴定出传染性喉气管炎病毒。在小母鸡的三起疫情中，有两起对抗菌治疗反应迅速。在这些病例中，溶血巴斯德氏菌被视为重要的继发性入侵者。
