Aspergillus fumigatus is the most common species in the Aspergillus group identified in human infection. It grows almost anywhere and on any type of substance; however, it’s particularly common in soil and decaying organic material. Other places to find A. fumigatus is in compost piles and cereals.
Blue-green to grey in colour, A. fumigatus has a wool or cotton-like texture. With a rapid growth rate, it grows well at 35°C.
Both allergenic and a major human pathogen, A. fumigatus has been reported to produce a number of mycotoxins that can cause both allergic and invasive disease. It is also the most common cause of aspergillosis in both humans and animals.
