Aspergillus flavus

March 25, 2014 John Ward

Aspergillus flavus is the second most common species (other than A. fumigatus) to be identified in human infection. In nature, it’s usually found growing in soil as well as dead plants and animals.

Initially, A. flavus appears yellow-green in colour, but with time, it turns a darker green. The texture is wool or cotton-like and sometimes granular.

A. flavus is allergenic and can be pathogenic to plants, humans and pets. The fungus can infect seeds of corn, peanuts, cotton and nut trees. It can cause aspergillosis as well as produce aflatoxin, a carcinogenic mycotoxin. It has also been reported to cause nasal sinus lesions and invasive disease.
