- Remarks:
- For details on positive control substances, see table 1
- Details on test system and experimental conditions:
- Two individual experiments were performed. The dose range-finding study with tester strains TA100 and TA1537 was reported as part of the first experiment. The first experiment was a direct plate assay. The second experiment was a pre-incubation assay and was performed to obtain more information about the possible mutagenicity of the test item.
METHOD OF APPLICATION: in agar (plate incorporation)
DURATION
- Preincubation period (second experiment): 30 ± 2 minutes at 70 rpm at 37 ± 1°C
- Exposure duration: 48 ± 4 h (in the dark at 37.0 ± 1.0 °C)
NUMBER OF REPLICATIONS:
- Doses of the test substance were tested in triplicate in each strain.
METHODS: The following solutions were successively added to 3 mL molten top agar: 0.1 mL of a fresh bacterial culture (10^9 cells/ml) of one of the tester strains, 0.1 mL of a dilution of the test item in Milli-Q water or control solution and either 0.5 mL S9-mix (in case of activation assays) or 0.5 mL 0.1 M phosphate buffer (in case of non-activation assays). The ingredients were mixed on a Vortex and the content of the top agar tube was poured onto a selective agar plate. After solidification of the top agar, the plates were inverted and incubated in the dark at 37.0 ± 1.0°C for 48 ± 4 h. In the pre-incubation assay (second experiment) this procedure was preceeded by pre-incubation of the solutions.
DETERMINATION OF CYTOTOXICITY
- Method: the reduction of the bacterial background lawn, the increase in the size of the microcolonies and the reduction of the revertant colonies.
- Other: precipitation of the test item was recorded
COLONY COUNTING:
- The revertant colonies were counted automatically with the Sorcerer Colony Counter. Plates with sufficient test item precipitate to interfere with automated colony counting were counted manually. Evidence of test item precipitate on the plates and the condition of the bacterial background lawn were evaluated when considered necessary, macroscopically and/or microscopically by using a dissecting microscope. - Evaluation criteria:
- DECISION CRITERIA:
A test item is considered negative (not mutagenic) in the test if:
a) The total number of revertants in the tester strain TA100 or WP2uvrA is not greater than two times the concurrent vehicle control, and the total number of revertants in tester strains TA1535, TA1537 or TA98 is not greater than three times the concurrent vehicle control.
b) The negative response should be reproducible in at least one follow-up experiment.
A test item is considered positive (mutagenic) in the test if:
a) The total number of revertants in the tester strain TA100 or WP2uvrA is greater than two times the concurrent vehicle control, or the total number of revertants in tester strains TA1535, TA1537, TA98 is greater than three times the concurrent vehicle control.
b) In case a follow up experiment is performed when a positive response is observed in one of the tester strains, the positive response should be reproducible in at least one follow up experiment.
In addition to the criteria stated above, any increase in the total number of revertants should be evaluated for its biological relevance including a comparison of the results with the historical control data range.
ACCEPTABILITY CRITERIA:
a) The vehicle control and positive control plates from each tester strain (with or without S9-mix) must exhibit a characteristic number of revertant colonies when compared against relevant historical control data generated at Charles River Den Bosch.
b) The selected dose-range should include a clearly toxic concentration or should exhibit limited solubility as demonstrated by the preliminary toxicity range-finding test or should extend to 5 mg/plate.
c) No more than 5% of the plates are lost through contamination or some other unforeseen event. If the results are considered invalid due to contamination, the experiment will be repeated.
