  • Title: Nephrotoxicity of Penicillium aurantiogriseum and P. commune from an endemic nephropathy area of Yugoslavia.
    Author: Macgeorge KM, Mantle PG.
    Journal: Mycopathologia; 1990 Dec; 112(3):139-45. PubMed ID: 2089255.
    Abstract:
    Seven out of nine Penicillium isolates from mouldy maize in Yugoslavia have been differentiated into the adjacent species P. aurantiogriseum and P. commune. Nephrotoxicity of cultured mycelia in the rat has been demonstrated for all isolates of both species and was correlated usefully, though indirectly, with the production of benzodiazepine secondary metabolites, notably auranthine. Shredded wheat (22 g) moulded by an example of each species and fed to a rat over 4 days elicited renal pathology in the P3 segment of proximal tubules, involving frequent pyknosis and extensive mitosis typical of this as yet uncharacterised toxin. The effect was attributed in P. aurantiogriseum at least partly to the spores. Prominent pathology was elicited by only 1g of spores given over 4 days.
