| genetic diversity of environmental aspergillus flavus strains in the state of são paulo, brazil by random amplified polymorphic dna. | aspergillus flavus is a very important toxigenic fungus that produces aflatoxins, a group of extremely toxic substances to man and animals. toxigenic fungi can grow in feed crops, such as maize, peanuts, and soybeans, being thus of high concern for public health. there are toxigenic and non-toxigenic a. flavus variants, but the necessary conditions for expressing the toxigenic potential are not fully understood. therefore, we have studied total-dna polymorphism from toxigenic and non toxigenic a ... | 2007 | 17923996 |
