title: Preliminary report on toxigenic fungal isolates of Aspergillus niger in market foods and foodstuffs.
abstract: 14 out of 22 fungal isolates of A. niger from market foods and foodstuffs were toxigenic to weanling rats. Approximately 2/3 of these cultures were highly toxigenic. Histopathologic changes were observed mostly in kidney with necrosis of the tubular epithelium and to a less extent in liver with centrolobular necrosis of the hepatic cells.
