Abstract: | The mutagenic effects of fiteen mycotoxins on Salmonella typhimurium strains TA1535, TA1537 and TA1538 and Saccharomyces cerevisiae strain D-3 were tested. Only aflatoxin B1 and sterigmatocystin were mutagenic. Both were active against S. typhimurium strain TA1538 and S. cerevisiae strain D-3; however, both required activation by the hepatic S-9 enzyme preparation. A positive correlation between the other mycotoxins reported to be carcinogenic and the two in vitro test systems employed was not demonstrated in our hands. |
