Pulmonary aspergillosis (K&E) (parrot C). Tissue from an individually housed and recently purchased, 6 month old African grey parrot found dead in the cage. Necropsy examination revealed focal necrosis of the left lung. This section stained by haematoxylin and eosin reveals septate fungal hyphae within the lung parenchyma. Similar hyphae were located in the walls and lumen of parabronchi, and within the walls of pulmonary blood vessels.
