The Platelia (Bio-Rad Laboratories) assay is approved by the US Food and Drug Administration (FDA) for In contrast, A. fumigatus is a human and animal pathogen and is the most common cause worldwide of human aspergillosis, an often-fatal disease that affects primarily immunocompromised individuals (Denning 1998). A. oryzae, A. sojae and A. niger are close relatives of A. flavus, but do not produce aflatoxins. Isolates belonging to the S group produce numerous sclerotia and fewer conidia than those of the L strain and respond differently to pH and growth and differentiation in light and dark environments.
