Applicant's summary and conclusion
- Conclusions:
- The test item B 1061 did not show mutagenic effects in both experiments. The number of revertant colonies was not increased in comparison with
the spontaneous revertants (solvent only). Cytotoxicity of the test item was not detected. The background lawn was visible and the number of rever- tants was not significantly decreased.
Therefore it can be stated, that under the test conditions, the test item B 1061 is not mutagenic in the Bacterial Reverse Mutation Test using
Salmonella typhimurium, strains TA 97a, TA 98, TA 100, TA 102 and TA 1535. - Executive summary:
Two valid experiments were performed.
First experiment: Five concentrations of the test item B 1061, dissolved in DMSO (ranging from 5020 to 50 µg/plate) were used. Five genetically manipulated strains of Salmonella typhimurium (TA 97a, TA 98, TA 100, TA 102, TA 1535) were exposed to the test item both in the presence and in the absence of a metabolic activation system (S9) for 48 hours, using the plate incorporation method.
None of the concentrations caused a significant increase in the number of revertant colonies in the tested strains. The test item didn't show any mutagenic effects in the first experiment.
No signs of toxicity towards the bacteria could be observed.
The sterility control and the determination of the titre didn't show any inconsistencies. The determined values for the spontaneous revertants of the negative controls were in the normal range. All positive controls showed mutagenic effects with and without metabolic activation.
Second experiment: To verify the results of the first experiment, a second experiment was performed, using three concentrations of the test item (ranging from 5051 to 1263 µg/plate) and a modification in study performance (pre-incubation method).
The test item B 1061 didn't show mutagenic effects in the second experiment, either.
No signs of toxicity towards the bacteria could be observed.
The sterility control and the determination of the titre didn't show any inconsistencies. The determined values for the spontaneous revertants of the negative controls were in the normal range. All positive controls showed mutagenic effects with and without metabolic activation.
Under the conditions of the test, the test item B 1061 didn't show mutagenic effects towards Salmonella typhimurium, strains TA 97a, TA 98, TA 100, TA 102 and TA 1535. Therefore, no concentration-effect relationship could be determined.
The test item B 1061 is considered as "not mutagenic under the conditions of the test".
