Sheep pulmonary adenomatosis (Jaagsiekte) in Libya : gross and histopathological evidence

Abstract

Gross and histopathological features indicative of sheep pulmonary adenomatosis (SPA) were detected in the right lung of an old female Beriberi sheep suffering from persistent respiratory distress. These were mainly dominated by multifocal papillomatous proliferation of the alveolar epithelium associated with abundant alveolar macrophage infiltrates. Four similar cases were further spotted in a ten-year histopathological survey of the disease in Tripoli area.
