The etiological factors causing acute pneumonia in feedlot cattle are complex in terms of their interactions with the host to cause clinical disease or death. The most significant agent is Pasteurella hemolytica, but it may be acting relatively late in the overall sequence of events.It is necessary to develop an overall strategy to determine the pathogenesis of the disease in the field. Approaches to this objective are discussed, with the emphasis on the role of the epidemiologist.
在饲养场牛群中,导致急性肺炎的病因在与宿主相互作用从而引发临床疾病或死亡方面较为复杂。最重要的病原体是溶血巴斯德氏菌,但它可能在整个事件序列中作用相对较晚。有必要制定一个全面的策略来确定该疾病在实际中的发病机制。本文讨论了实现这一目标的方法,重点强调了流行病学家的作用。
