A Case of Pulmonary Blastomycosis in a Common Eland (Taurotragus Oryx)

Abstract

This case report describes for the first time pulmonary blastomycosis in a captive common eland (Taurotragus oryx). The animal has been in captivity for over 14 years and the clinical signs observed before death were non-specific. The carcass was examined grossly and histologically using special stains. There were yellowish, firm and gritty nodules of varying sizes (0.5–2 cm in diameter) on the pleura, in the lung, mediastinal lymph nodes and pericardium. The nodules showed pyogranulomatous inflammation and broad based budding yeast (PAS, Giemsa positive and ZN negative) consistent with Blastomyces dermatitidis. Regular screening of soil and environment including animals in captivity should be encouraged to avert possible spread of the mold in favorable conditions. Public awareness should be improved on fungal diseases.
