✦ Synopsis
The cytogenetic effects of fungal metabolites produced by 113 strains belonging to 36 fungal species and isolated from 5 substrates of commercial poultry feedstuffs were tested for their effect on the growing root meristems of Alliurii cepa.
The fungal metabolites of Paecilontyces canescens, Aspergillus ,fumigatus, Syncrphninstruni rucemosum, Aspergillus ferreiis and Mucor hienmlis strongly suppressed cell division. Metabolites from other strains had less effect on cell division but permitted the appearance of several abnormalities through different mitotic stages. In general, chromosomal aberrations were more obvious with metabolites of Aspergillus species, Mucor c ircinello ides and Cladosporium cladosporio ides.
The mutagenic effects produced by these fungal metabolites reflect the risk that might take place through the consumption of these contaminated feedstuffs.
