Fungus Aspergillus flavus
False-colour scanning electron micrograph (SEM) of the fungus Aspergillus flavus,a causative agent of liver cancer and aspergillosis. Here,a fungal thread of the vegetative mycelium has developed at its tip a spore-producing fruiting body. Found in soil and decaying vegetation,this fungus produces aflatoxin,a virulent toxin which may contaminate stored food (particularly carbohydrates). It is a toxin known to induce liver cancer. A.flavus also is one of the Aspergillus species which causes aspergillosis,more commonly in the tropics. This is a respiratory infection in people with weakened lungs,or lowered resistance,and may be fatal. Magnification: x300 at 6x7cm size
