- Details on test system and experimental conditions:
- Eight hours before the start of each experiment, the nutrient broth was inoculated. For the incubation of strains TA97a, TA98, TA100, TA102; ampicilline was added to the nutrient broth (25 mg/L), for the incubation of strain TA102, tetracycline was added (2 mg/L) in addition to ampicilline. TA1535 was incubated without the addition of antibiotics. The flasks were incubated at 37 ± 1°C for 8h. On the day of the test, the overnight cultures were checked for growth. The incubation time was 48h at 37 ± 1°C. The plate incorporation method was used in this experiment (cfr "Any other information on materials and methods incl. tables").
- Rationale for test conditions:
- Pre-test results
- Evaluation criteria:
- The colonies were counted visually, the numbers were recorded. A spreadsheet software was used to calculate mean values and standard deviations of each treatment, solvent control and positive control. The increase factor f(I) of revertant induction (mean revertants divided by mean spontaneous revertants) and the absolute number of revertants (“Rev. abs.”, mean revertants less mean spontaneous revertants) were also calculated. A test substance is considered to have mutagenic potential, if a significant, reproducible increase of revertant colonies per plate (increase factor ≥ 2) in at least 1 strain can be observed. A concentration-related increase over the range tested can also be taken as a sign of mutagenic activity.

- Additional information on results:
- First Experiment:
5 concentrations of the test substance, dissolved in DMSO (ranging from 5 to 500 µg/plate) were used. Five genetically changed strains of Salmonella typhimurium (TA97a, TA98, TA100, TA102 (genetically manipulated) and TA1535) were exposed to the test substance both in the presence and in the absence of a metabolic activation system (S9-mix, rat liver S9-mix induced by Aroclor 1254) for 48h, 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 substance did not show any mutagenic effects in the first experiment. The test substance showed no precipitates on the plates in all tested concentrations. No signs of toxicity towards the bacteria could be observed. The sterility control and the determination of the titre did not 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 7 concentrations of the test substance (ranging from 8 to 500 µg/plate) and a modification in study performance (pre-incubation method). The test substance did not show mutagenic effects in the second experiment, either. The test substance showed no precipitates on the plates in all tested concentrations. No signs of toxicity towards the bacteria could be observed. The sterility control and the determination of the titre did not 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.
The study was considered valid.
In conclusion, the test substance did not show mutagenic effects towards Salmonella typhimurium, strains TA97a, TA98, TA100, TA102 and TA1535. Therefore, no concentration-effect relationship could be determined. The test substance was considered as “not mutagenic under the conditions of the test”.
Applicant's summary and conclusion
- Conclusions:
- Under the study conditions, the test substance was considered as not mutagenic (reverse mutation assay).
- Executive summary:
An in vitro reverse mutation assay was conducted to determine the mutagenic potential of the test substance according to OECD Guideline 471 and EU Method B.13/14, in compliance with GLP. Two experiments were performed. In the first experiment, 5 concentrations of the test substance, dissolved in DMSO (ranging from 5 to 500 µg/plate) were used. 5 strains of Salmonella typhimurium (TA97a, TA98, TA100, TA102 (genetically manipulated) and TA1535) were exposed to the test substance both in the presence and in the absence of a Aroclor induced rat liver S9-mix metabolic activation system for 48 h, 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 substance showed no precipitates on the plates in all tested concentrations. To verify the results of the first experiment, a second experiment was performed, using 7 concentrations of the test substance (ranging from 8 to 500 µg/plate) and a modification in study performance (pre-incubation method). The test substance did not show mutagenic effects in the second experiment, either. The test substance also showed no precipitates on the plates in all tested concentrations. Further, in both the experiments, no signs of toxicity towards the bacteria could be observed. The sterility control and the determination of the titre did not show any inconsistencies. The determined values for the spontaneous revertants of the negative controls were also in the normal range. All positive controls showed mutagenic effects with and without metabolic activation. The study was therefore considered valid.Therefore, the test substance was considered to be non-mutagenic under the conditions of the reverse mutation assay(Geitlinger, 2015)
