Method
Species / strainopen allclose all
- Species / strain / cell type:
- S. typhimurium TA 1535, TA 1537, TA 98, TA 100 and E. coli WP2
- Species / strain / cell type:
- S. typhimurium TA 1538
- Metabolic activation:
- with and without
- Metabolic activation system:
- S9 fraction of liver from rats induced with Aroclor 1254
- Test concentrations with justification for top dose:
- 5, 10, 50, 100, 500, 1000 and 5000 µg/0.1 ml. The top dose is the highest dose recommeneded by test guidelines.
- Vehicle / solvent:
- DMSO
Controls
- Untreated negative controls:
- no
- Negative solvent / vehicle controls:
- yes
- True negative controls:
- no
- Positive controls:
- yes
- Positive control substance:
- 9-aminoacridine
- 2-nitrofluorene
- N-ethyl-N-nitro-N-nitrosoguanidine
- other: 2-aminoanthracene
- Details on test system and experimental conditions:
- Each Petri dish contained: 1) approx. 20 ml of minimum agar (Agar, Difco Laboratories, Detroit, Michigan, U.S.A., plus salts (Vogel-Bonner Medium E) and glucose), 2) 0.1 ml of the solution of the test substance or the vehicle and 0.1 ml of a bacterial culture (in nutrient broth, Difco Laboratories, Detroit, Michigan, U.S.A., 0.8% plus 0.5% NaCl) in 2.0 ml of soft agar. The soft agar was composed of: 100 ml of 0.6% agar solution with 0.6% NaCl and 10 ml of a solution of 1-histidine, 0.5 mM (Fluka, Buchs, Switzerland) and +biotin 0.5 mM (Fluka, Buchs, Switzerland). In the experiments in which the substance was metabolically activated, 0.5 ml of an activation mixture was added also.
In the experiments without and with the addition of microsomal activation mixture three Petri dishes were prepared per strain
and per group (i.e. per concentration or per control group).
The plates were incubated for about 48 hours at 37 C in darkness. - Rationale for test conditions:
- per referenced methods
- Evaluation criteria:
- The test substance is generally considered to be nonmutagenic if the colony count in relation to the negative control is not doubled at any concentration.
- Statistics:
- Arithmetic means were calculated for each test group.

Applicant's summary and conclusion
- Conclusions:
- Under these standard test conditions, there was no evidence of the induction of point mutations by TK 12 184 in S. typhimurium or E. coli at concentrations up to 5000 µg/plate with and without metabolic activation.
