Abstract

Classification of pneumonias takes on many characteristics, each of which seem to add to the confusion in diagnosing respiratory problems. Pierson divides respiratory feedlot yearling deaths into three groups: bronchial, interstitial, and metastatic. He then describes each entity of that group. He classifies pulmonary emphysema of weaned calves as an interstitial pneumonia. Other respiratory entities in this group with confusing morphological terms are: bovine pulmonary emphysema; acute bovine pulmonary emphysema, or ABPE; St. George disease; fog fever; atypical interstitial pneumonia, which is currently the most popular; pulmonary adenomatosis; silo filler's disease; cow asthma; hypersensitive pneumonitis; extrinsic allergic alveolitis; "Urner pneumonie"; bovine farmer's lung; acute alveolar emphysema and edema; panters; and lungers.
