Aspergillus fumigatus. Coloured Scanning Electron Micrograph (SEM) of a fruiting body of the fungus Aspergillus fumigatus, which causes aspergillosis in humans. The round structures are spores, about to be released into the air. A. fumigatus grows in household dust and decaying vegetable matter. Al- though harmless to healthy people the fungus can cause complications in sufferers of tuberculosis or asthma, or in people with damaged immunity. Inhalation of the spores can cause infection of the lungs (aspergillosis), allergy, and invasive disease, where the fungus spreads to the brain, kidneys, liver and skin. Magnification unknown.
