The mutagenicity of palmotoxin Bo and of aflatoxin M1 relative to that of aflatoxin B1, the potent mutagen, was studied in five Ames' Tester Strains of Salmonella typhimurium (TA-98, TA-100, TA-1535, TA-1537, TA-1538). Aflatoxins B1 and M1 are both highly mutagenic in a microsome-mediated system in TA-100. The prediction of the relative carcinogenicity of aflatoxin M1 to aflatoxin B1 posed by the mutation of TA-100 is probably more authentic than TA-87. The mutagenic potency of palmotoxin Bo is less than that of either aflatoxin B1 or M1. |
