Emericella nidulans is a widespread soil fungus. Indoors it is found in carpet and mattress dust and decomposing wood.
Emericella nidulans has been reported as a
causative agent of aspergillosis in humans and animals.
Emericella nidulans poses inhalation and deep skin
(dermal) inoculation health risks to persons with weak immune
systems. It also poses health risks related to major barrier
breaks such as corneal perforation, major surgery, peritoneal
or venous catheter presence, and injection drug
use.
