| Virulence Factors:
| Usually produces only flatoxin B1 and B2, which are important mycotoxins. May also produce some other mycotoxins, such as cyclopiazonic acid, gliotoxin, kojic acid and sterigmatocystin. However, All strains of A. flavus does not produce all mycotoxins and there are strains that do not produce mycotoxins at all. |
