title: The pathological features of an interstitial pneumonia of goats.
abstract: An interstitial pneumonia in goats which predominantly affects the caudal lung lobes is described. It is characterized microscopically by hypertrophy of type 2 pneumocytes, the presence of an abundant eosinophilic, PAS-positive material within alveolar spaces, and a diffuse and focal lymphoid infiltration of alveolar septa. The material present within alveolar spaces is considered to be composed of surfactant and fibrin. Although the aetiology is not known the gross and microscopic appearance suggests that a retro-virus may be involved.
