Saggital section of kidney from a German shepherd dog with disseminated aspergillosis. There are granulomata within the medulla, and fungal material within the renal pelvis. Renal involvement in canine dissemianted aspergillosis is common, and the demonstration of fungal hyphae within urine sediment is a useful screening test.
Pigmentation of Aspergillus versicolor colonies ranged from pale green to greenish-beige, pink-green, dark green and brown. Reverse is usually reddish. The growth rate is usually slow. Cultured on Sabouraud dextrose agar with chloramphenicol.
