A. fumigatus neither infects plants nor is of any industrial value, instead it is a human pathogen that infects human lungs causing both invasive and noninvasive human aspergillosis, especially to those who are immunocompromised patients and can be fatal (Rankin 1953; Denning 1998). government site. This supports the idea that gene expansion in A. oryzae resulted from its domestication as a species better adapted for fermentation than is the typical A. flavus. After A. fumigatus, A. flavus is the second leading cause of invasive aspergillosis and it is the most common cause of superficial infection. official website and that any information you provide is encrypted Some pets may suffer liver damage without showing any signs in the early stages of aflatoxin poisoning and if they continue eating contaminated food, they may die suddenly.
