AB - The present report documents a case of acute aspergillosis
and bacillosis in a canary in which the bacillus and fungal colonization was
confined to the trachea and lung. A male canary was presented to clinic with
a history of the presence of watery diarrhea and swelling in the left intertarsal
joint without weight bearing. Supportive care was attempted but the bird did
not improve and 48 h after beginning of respiratory signs, the bird died. At
necropsy, symmetric necrotic zone were seen in the junction of syrinx to lung.
The trachea was edematous and congested. The intestine was edematous and dilated.
Histopathologic examination of lungs and trachea revealed infiltrative reactions
of aspergillosis. Fungal hyphae with dichotomous divisions characteristic of
aspergilli were clearly demonstrated in the trachea and lung by PAS and H&E
stains. The pinkish amorphous material in the spleen was demonstrated to be
amyloid with Congo red stain. Isospora life stages in the enterocytes were detected.
