[Effect of aflatoxin B1, of some of its metabolites and of culture extracts from "Aspergillus parasiticus" on virulent bacteriophages (author's transl)].
Aflatoxin B1 has different effects on bacteriophages: it inhibits some virulent strains and induces lysogenic bacteria. In this experiments we have used several classes of phages of enterobacteria, streptococci, staphylococci and Bacillus. We have tested different substances: cristallized aflatoxin B1, metabolites of the same mycotoxin and culture extracts from a toxinogenic strain of Aspergillus parasiticus. The inhibitory effects observed are different for each strain, and for a given phage the substances do not show the same action.
