- Details on test system and experimental conditions:
- Experiment 1: Standard plate test
Test tubes containing 2 ml soft agar kept in a water bath at 42-45°C, and remaining components added in the following order:
0.1 ml test solution or vehicle
0.1 ml bacterial suspension
0.5 ml S-9 mix (in tests with metabolic activation) or 0.5 ml phosphate buffer (in tests without metabolic activation).
After mixing, the samples are poured onto Vogel-Bonner agar plates (S. Typhimurium) or minimal agar plates (E.Coli).
Experiment 2: Preincubation assay
0.1 mL test solution or vehicle, 0.1 mL bacterial suspension and 0.5 mL S9 mix (with metabolic activation) or phosphate buffer (without metabolic activation) are incubated at 37°C for the duration of about 20 minutes using a shaker. Subsequently, 2 mL of soft agar is added and, after mixing, the samples are poured onto the agar plates within approx. 30 seconds.
Experiment 1 & 2:
In each experiment 3 test plates per dose or per control used; after incubation at 37°C for 48-72 hours in the dark, the bacterial colonies (his+ revertants or Trp + revertants) are counted.
Positive control:
with metabolic activation: 2.5 μg/plate 2-aminoanthracene for each Salmonella strain and 60µg/plate for E. coli WP2 uvrA;
without metabolic activation: 5 μg/plate N-methyl-N'-nitro-N-nitrosoguanidine for TA 100 and TA 1535, 10 μg/plate 4-nitro-o-phenylendiamine for TA 98, 100 μg 9-aminoacridine chloride monohydrate for TA 1537 and 10 μg/plate methyl-N- nitro-N-nitrosoguanidine for E. Coli WP2 uvrA, all positive substances were dissolved in DMSO.
The titer was determined and in regularly measurements the strain characteristics were checked. Sterility control performed. - Evaluation criteria:
- Acceptance criteria
Generally, the experiment is considered valid if the following criteria are met:
• The number of revertant colonies in the negative controls was within the normal range of the historical control data for each tester strain.
• The sterility controls revealed no indication of bacterial contamination.
• The positive control articles both with and without S-9 mix induced a significant increase in the number of revertant colonies within the range of the historical control data or above.
• The titer of viable bacteria was > 10^8/ml.
Assessment criteria
The test chemical is considered positive in this assay if the following criteria are met:
• A dose-related and reproducible increase in the number of revertant colonies, i .e. about doubling of the spontaneous mutation rate in at least one tester strain either without S-9 mix or after adding a metabolizing system.
A test substance is generally considered nonmutagenic in this test if:
• The number of revertants for all tester strains were within the historical negative control range under all experimental conditions in two experiments carried out independently of each other. - Statistics:
- Mean and standard deviation. No further data.
