- Additional strain / cell type characteristics:
- other: All strains are uvrB-deficient (to reduce the repair of chemically induced lesions in the DNA) and are rfa In addition strainsTA98 and TAI00 contain the plasmid pKMIOl, which makes them more sensitive than their parent strains.

METHOD OF APPLICATION: in agar (plate incorporation)
DURATION
- Exposure duration: 12 hour
Other; The strains were checked periodically for relevant genetic markers and for rfa by crystal violet sensitivity; T A98 and T AI00 were checked for ampicillin resistance. - Rationale for test conditions:
- Not specified .
- Evaluation criteria:
- The numbers of Histidine-independent revertants for each Salmonella typhimurium strain were taken from the linear portion of dose-response curves after the background was subtracted. The range of spontaneous revertants was 25-55 for TA1535, 7-25 for TA1537, 10-30 for TA1538, 30-60 for TA98, and 100-180 for TA100.A positive response was defined as a reproducible, dose-related increase in the number of revertants. Usually, a chemical was mutagenic in more than one strain.
- Statistics:
- Mean ±standard deviation was observed.

Applicant's summary and conclusion
- Conclusions:
- Pararosaniline (467-62-9) was evaluated for its mutagenic potential in Salmonella typhimurium strains TA1535, TA1536, TA1537, TA1538, and TA98and TAI00 by bacterial reverse mutation assay. The test results were considered to be negative in the presence and absence of S9 mix.
- Executive summary:
Pararosaniline was assessed for its possible mutagenic potential. For this purpose bacterial reverse mutation assay was performed on Salmonella typhimurium strains TA1535, TA1536, TA1537, TA1538, TA98, and TAI00.The test material was exposed at the concentration of 0 and 250ug /plate byplate incorporation Method.The test material was exposed in the presence and absence of metabolic activation.The numbers of Histidine-independent revertants for each Salmonella typhimurium strain were taken from the linear portion of dose-response curves after the background was subtracted. The range ofspontaneousrevertantswere as per the control. No mutagenic effect was observed. Therefore Pararosaniline was considered to be non mutagenic in Salmonella typhimurium strains TA1535, TA1536, TA1537, TA1538, TA98 and TAI00. Hence the substance cannot be classified as gene mutant in vitro.
