At present it is widely accepted that the damages of the nasal turbinate bones and mucus caused by Bordetella bronchiseptica laid the foundation for the invasion toxigenic Pasteurella multocida. The mixture of Bordetella bronchiseptica and toxigenic Pasteurella multocida, together with some other factors, is the main cause of natural AR.

经过多年研究，现在大多数学者认为，支气管败血波氏杆菌能引起一定程度的鼻粘膜和鼻甲骨损害，但这些病变的严重后果是为正常猪鼻腔不能定居的产毒素多杀巴氏杆菌建立感染铺平道路，Bb和T+Pm的混合感染加上非传染因素交织在一起，是在自然条件下临床型AR的发生原因。
