Additional information on results:
Observations:
Positive, concentration-related results were observed in TA 1537, TA 1538 and TA 98 (with and without metabolic activation) and in TA 100 (with activation). For each strain the positive effect was much greater with activation.
Negative results were observed for TA 1535 (with and without metabolic activation) and TA 100 (without activation).
