Constituent 1
Method
- Target gene:
- All these strains contain mutations in the histidine operon, thereby imposing a requirement for histidine in the growth medium.
S. typhimurium TA 1535 his G46 rfa -Δ uvr B -is derived from the his G46 strain but is a deep rough * excision repair deficient ** strain which is highly sensitive to base-pair substitution mutagens.
S. typhimurium TA 1537 his C3076 rfa -Δ uvr B -is a strain derived from a his C3076 mutant and carries deep rough and excision repair deficiency mutations. This strain is highly sensitive to frameshift mutagens.
S. typhimurium strain TA 1538 his D30S2 rfa -Δ uvr B-is a strain derived from a his D3052 mutant, and also carries deep rough and excision repair deficiency mutations. This strain is highly sensitive to frameshift mutagens.
S. typhimurium TA 98 his D3052 rfa - Δ uvr B - R + is also derived from a his 03052 mutant, but in addition to the deep rough and excision repair deficiency mutations it also carries a resistance transfer factor. This additional factor makes TA 98 very sensitive to the weaker frame-shift mutagens.
S. typhimurium TA 100 his G46 rfa -Δ uvr B -R + derived from the his G46 strain and carries the deep rough and excision repair deficiency mutations and also a resistance transfer factor. This additional factor makes TA 100 particularly sensitive to basepair substitution mutagens.
*All the five strains described above carry a mutation known as deep rough which affects the cell membrane so that the normal lipopolysaccharide cell coat is defective. These strains therefore allow a greater permeability of test agents across this membrane and into the cell.
** In bacteria almost all the primary dramage caused to DNA bya mutagen is repaired by excision and recombinatim repair systems so that normalIy only a small percentage of the potential mutagenic damage is expressed. The five tester strains used here lack this excision repair thus making them more sensitive to mutagens.

DURATION

NUMBER OF REPLICATIONS: the mutation assay was performed in triplicate and an independent repeat was also done.
NUMBER OF CELLS EVALUATED: colonies of 0.1 mm or more in diameter were counted with a Biotran III automated counter (New Brunswick Inc., N.J., U.S.A.) at maximum sensitivity.
DETERMINATION OF CYTOTOXICITY
- Method: number of colonies and the background lawn was detemined - Evaluation criteria:
- A positive mutagenic response is recorded if there is:
i) for S. typhimurium strains TA 1535, TA 1537, TA 1538 and TA 98, at least a doubling of the mean concurrent control values at some
concentration of the test substances and for S. typhimurium strain TA 100, a 1.5-fold increase over the control value.
ii) a dose related response, although at high dose levels this relationship may be inverted because of, for example, (1) toxicity
to the bacteria generally, (2) specific toxicity to the mutants and (3) inhibition of foreign compound metabolising enzymes where
mutagens require metabolic activation by the liver.
iii) a reproducible effect in independent tests. - Statistics:
- not applicable

- not examined
- Positive controls validity:
- valid
- Additional information on results:
- Inadequate responses were obtained with 2-aminoanthracene with strains TA 1537 and TA 100 in the first test, so it was decided to retest
Berolamine 715 with these strains in the presence of S-9 mix (Test 3). The results of this test confirmed that the test substance was not
mutagenic in these strains in the presence of S-9 mix. - Remarks on result:
- other: all strains/cell types tested
- Remarks:
- Migrated from field 'Test system'.
Any other information on results incl. tables
With this test it is not possible to identify certain oxidising mutagens, cross-linking agents and hydrazines. Such substances may be detected by E.coli WP2 strains or S. typhimurium TA102 which have an AT base pair at the primary reversion site in stead of GC base pairs which the strains tested in this study have. Although structure does not give rise for this specific concern.
2-Aminoanthracene was used as the sole indicator of the efficacy of the S9-mix.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
In the Ames test the test substance was not mutagenic in any of the 5 strains used in this study either in the presence or absence of S-9 mix. - Executive summary:
In the Ames test the test substance was not mutagenic in any of the 5 strains used in this study either in the presence or absence of S-9
mix. Toxicity to the background lawn of bacteria was recorded at concentrations above 100 µg/plate.With this test it is not possible to identify certain oxidising mutagens, cross-linking agents and hydrazines. Such substances may be detected by E.coli WP2 strains or S. typhimurium TA102 which have an AT base pair at the primary reversion site in stead of GC base pairs in the strains tested in this study.
