Abstract

A four-year-old male elk (Cervus elaphus nelsoni) was diagnosed as pulmonary aspergillosis and renal oxalosis. Clinical signs were coughing, sneezing, respiratory distress, salivation, moderate anorexia, and progressive emaciation. Main gross lesions were fibrinopurulent tonsillitis, diffusely fibrinous pleuritis, and distinct lobar pneumonia with purple red in color. Most of the pulmonary lobes had numerous well demarcated 0.5 to 2 cm yellowish white discrete or confluent nodules that were surrounded by pale red zones. Histopathologically, the affected lungs were disseminated necrotizing pyogranulomas including fungal hypae, vasculitis, and diffusely fibronecrotic pleuritis. The renal lesions were composed of extensive tubular necrosis with large numbers of rosette-formation by birefringent oxalate crystals. Aspergillus fumigatus was isolated from lesions of the lungs. It seems to be a first report for pulmonary aspergillalis and renal oxalosis of a farmed elk in Korea.
