牛过敏性肺炎：与发霉干草相关的急性暴发。

Can J Comp Med. 1978 Jan;42(1):10-5.

An outbreak of acute bovine atypical interstitial pneumonia is reported in association with feeding mouldy hay. Results of serological investigation and of provocation challenge indicated a hypersensitivity pneumonitis due to allergens of Micropolyspora faeni. Macroscopic and microscopic pulmonary changes were predominantly those of oedema and emphysema. These lesions were contrasted with more chronic changes reported in allergic pneumonitis of housed cattle.

据报道，一起急性牛非典型间质性肺炎疫情与喂食发霉干草有关。血清学调查和激发试验结果表明，这是由嗜热放线菌过敏原引起的过敏性肺炎。大体和显微镜下的肺部变化主要是水肿和肺气肿。这些病变与圈养牛过敏性肺炎中报道的更慢性的变化形成对比。
