The fungus was originally classified as a subspecies of A. flavus called Aspergillus flavus subsp. parasiticus (Speare) due to its strong resemblance to A. flavus. Indeed, this fungus is very closely related to A. flavus [3] and is often misidentified as the latter. [3] However, the two species are separable based on morphological features. [3]
Aflatoxin B 1 is considered the most toxic and is produced by both Aspergillus flavus and Aspergillus parasiticus. Aflatoxin M 1 is present in the fermentation broth of Aspergillus parasiticus, but it and aflatoxin M 2 are also produced when an infected liver metabolizes aflatoxin B 1 and B 2. Aflatoxin B 1 and B 2 (AFB), produced by A. flavus ...
Aspergillus flavus is unique in that it is a thermotolerant fungus, so can survive at temperatures that other fungi cannot. [12] [13] A. flavus can contribute to the storage rots, especially when the plant material is stored at high moisture levels. A. flavus grows and thrives in hot and humid climates. [10]
Aflatoxin B 1 is an aflatoxin produced by Aspergillus flavus and A. parasiticus.It is a very potent carcinogen with a TD 50 3.2 μg/kg/day in rats. [4] This carcinogenic potency varies across species with some, such as rats and monkeys, seemingly much more susceptible than others.
In March 2010, Aspergillus covered 837 species of fungi. [5] Notable species placed in Aspergillus include: Aspergillus flavus is a notable plant pathogen impacting crop yields and a common cause of aspergillosis. Aspergillus fumigatus is the most common cause of aspergillosis in individuals with an immunodeficiency.
Aflatoxin is produced by two species of Aspergillus, A. flavus and A. parasiticus, which are known to affect plants including cereal grains, figs, nuts, and tobacco. [2] Cereal grains are one of the main ingredient in animal feed. The animals most at risk of having serious problems with aflatoxins are trout, ducklings, and pigs, while cattle ...

Aflatoxin M 1 is a chemical compound of the aflatoxin class, a group of mycotoxins produced by three species of Aspergillus – Aspergillus flavus, Aspergillus parasiticus, and the rare Aspergillus nomius – which contaminate plant and plant products. Aspergillus flavus produces only B-type aflatoxins.
