The frequency of occurrence and four principal kinds aflatoxin concentration in maize seeds grown Burkina Faso was investigated. Ten (10) samples collected, were analyzed by high performance liquid chromatography (HPLC) with post-column derivatisation after immunoaffinity column cleanup. Eight strains Aspergillus section Flavi previously isolated from these cultivated on “Aspergillus flav...

aflatoxins are secondary toxic metabolites produced by some aspergillus spp. particularly, aspergillus flavus and a. parasiticus that contaminate food and feed. the objective of this study was to evaluate the contamination of feedstuffs with aspergillus spp. and detect genes involved in the aflatoxin biosynthesis pathway of a. flavus and a. parasiticus isolates. a total of 110 cow feed samples ...
