4. Conclusions
Based on several approaches, our study led us to draw the following
conclusions: Brazil nuts may harbor A. pseudonomius, a sibling species of
A. nomius. To date, the bestway of distinguishing these sibling species is
to analyze β-tubulin or calmodulin gene sequence. We also concluded
that A. pseudonomius strains might be able to produce both B and Gtype
aflatoxins
