Aspergillus nidulans

A rapidly growing fungus that produces a dark green colony within ten days, when incubated at 25oC (77oF). It is very common worldwide especially in the subtropical and tropical regions. It can be isolated from air, soil, sand beaches, mangrove swamp, brackish soil, sewage sludge, compost, foodstuffs, animal dung, bird feathers, and bees. It can produce the mycotoxin sterigmatocystin. In man, it occurs primarily as the causal agent of mycetomas and rarely as a cause of pulmonary aspergillosis. It is a animal pathogen, causing aspergillosis in horses and poultry.
