Bacterial pathogens play an important role in causing respiratory disease in domestic poultry species. In many cases, the bacterial component of a respiratory disease colonizes the respiratory system only after a primary viral or environmental insult. Colonization of the airsacs of a chicken by Escherichia coli following an infectious bronchitis virus infection is an example of secondary bacterial invasion. In other cases, the bacterial component of the respiratory disease is the primary initiating cause of the disease. Examples of primary bacterial respiratory disease are infectious coryza in chickens and fowl cholera in chickens and turkeys.
细菌性病原体在引起家禽呼吸道疾病方面起着重要作用。在许多情况下，呼吸道疾病的细菌成分只有在原发性病毒感染或环境损伤之后才会在呼吸系统中定植。传染性支气管炎病毒感染后大肠杆菌在鸡气囊中的定植就是继发性细菌感染的一个例子。在其他情况下，呼吸道疾病的细菌成分是该疾病的主要起始原因。原发性细菌性呼吸道疾病的例子有鸡的传染性鼻炎以及鸡和火鸡的禽霍乱。
