Bacterial Reverse Mutation Test (Ames) Multi-Domain Example (GT, TS, TX, RELREF)

The bacterial reverse mutation test uses amino acid-requiring strains of Salmonella typhimurium (S. typhimurium) and Escherichia coli (E. coli) to detect point mutations, which involve substitution, addition or deletion of one or a few DNA base pairs. The principle of this bacterial reverse mutation test is that it detects chemicals that induce mutations which revert mutations present in the tester strains and restore the functional capability of the bacteria to synthesize an essential amino acid. The revertant bacteria are detected by their ability to grow in the absence of the amino acid required by the parent tester strain.

Example

This is an example showing the report table, trial design, and results from a study's in vitro bacterial reverse mutation test using 4 different amino acid-requiring strains of S. typhimurium and 1 strain of E. coli to detect point mutations.

This table shows the assay results for study 8325064, test article TA1, and 3 strains of salmonella (TA98, TA100, and TA1535) at varying concentrations. For brevity, the remaining tables (e.g., additional strains, samples prepared without metabolic activation) are not included. For ease of reference in the table below, each row has been labeled in the right-hand margin with the applicant-defined trial set label (e.g., SetA). For brevity, only the four bolded sets are represented in the following example datasets.

This example Trial Summary (TS) dataset, shows many informational fields that provide context at the study level.

Please add a row column to your dataset.

This example Trial Set (TX) dataset shows information about the test conditions for SetA and SetR in this study. For brevity, the dataset does not show information for SetF, SetG, or any other sets. A fully formed TX dataset for this example study would include information about the test conditions for all sets.

Note that there are three trial set parameters that link to other important datasets: SPTOBID, APDEVID, and SMKRGM.

SPTOBID (Applicant-Defined Tobacco Product ID) is used to uniquely identify the tobacco product. The value of SPTOBID (e.g., CIG01a) matches the value for SPTOBID in all the TOPARMCD-TOVAL pairs in the Tobacco Product Identifiers and Descriptors (TO) dataset example in Section 3.1.2, Product Design Parameters and Conformance Testing, Example 1. The TOPARMCD-TOVAL pairs identify this unique product, CIG01a. The TO domain is described in Section 2.8.8.1, Tobacco Product Identifiers and Descriptors (TO).
The value of APDEVID (e.g., PUFFMASTER3K) matches the value of SPDEVID in all the DIPARMCD-DIVAL pairs that identify this unique device in the DI dataset. SPDEVID is the applicant-defined device identifier that is used to uniquely identify the device in the Unique Device Identification (DI) dataset (see also Section 2.8.9.7, SEND Device Identifiers (DI)). This is shown in the DI dataset in Section 3.1.3.2, HPHCs, Other Constituents, and Smoking/Vaping Regimens, Example 1.
SMKRGM serves as a link to the Device-In Use Properties (DU) domain (see also Section 2.8.9.8, SEND Device-In-Use (DU)), where a matching value of SMKRGM indicates parameters of the smoking regimen performed by the smoking machine, as in the DU dataset in Section 3.1.3.2, HPHCs, Other Constituents, and Smoking/Vaping Regimens, Example 2.

Rows 1-22:	Show trial set parameters and trial set values that are the test conditions specific to set SetA which is the vehicle control (i.e., Strain of TA98, vehicle control with concentration value of 0). SetA is associated with the first row, labeled "SetA", in the report table for example study 8325064.
Rows 23-44:	Show trial set parameters and trial set values that comprise the test conditions for the set SetF which is the strain of TA98 with a concentration value of 500 µg/plate. SetF is associated with the sixth row, labeled "SetF", in the report table for example study 8325064.
Rows 45-66:	Show trial set parameters and trial set values that comprise the test conditions for the set SetG which is the strain of TA98 with a concentration value of 1600 µg/plate. SetG is associated with the seventh row, labeled "SetG", in the report table for example study 8325064.
Rows 67-88:	Show trial set parameters and trial set values that comprise the test conditions for the set SetR which is the strain of TA100, positive control with a concentration value of 2 µg/plate. SetR is associated with the eighteenth row, labeled "SetR", in the report table for example study 8325064.

Please add a row column to your dataset.

REFID values are defined by the applicant to uniquely identify the observational unit within an experimental unit. In the simplified diagram of an assay procedure (below), the test tube that contains the possible mutagen is an example of an entity that would have a REFID indicating information at the level of trial set. The petri plate created from that test tube and used to count revertant numbers is an example of an entity that would be at an observational level.

This picture does not depict the more complicated procedures, trial sets, or observational units for the example study. For study 8325064, the applicant chose to define the REFIDs at the trial set level with a single character (e.g., A, F, G, R) and chose to define REFIDs at the observational level based on the location of each tube in 1 of multiple exposure/incubation plates (e.g, 6_1 for plate 6, position 1).

Row 1:	Shows the value of REFID=A. This REFID refers to the trial set with a SETCD of "SetA", as defined in the TX dataset. LEVEL=1 and LVLDESC="EXPERIMENTAL UNIT/TRIAL SET". TRIAL SET indicates this identifier relates to the entire trial set. EXPERIMENTAL UNIT indicates this identifier received the intervention article, DMSO.
Rows 2-6:	Show the values of 5 observational units (1_1 through 1_5) that are within the parent experimental unit, REFID=A.
Row 7:	Shows the value of REFID=F. This REFID refers to the trial set with a SETCD of "SetF", as defined in the TX dataset. LEVEL=1 and LVLDESC="EXPERIMENTAL UNIT/TRIAL SET". TRIAL SET indicates this identifier relates to the entire trial set. EXPERIMENTAL UNIT indicates this identifier received the intervention article, TA1.
Rows 8-10:	Show the values of 3 observational units (6_1 through 6_3) that are within the parent experimental unit, REFID=F.
Row 11:	Shows the value of REFID=G. This REFID refers to the trial set with a SETCD of "SetG", as defined in the TX dataset. LEVEL=1 and LVLDESC="EXPERIMENTAL UNIT/TRIAL SET". TRIAL SET indicates this identifier relates to the entire trial set. EXPERIMENTAL UNIT indicates this identifier received the intervention article, TA1.
Rows 12-14:	Show the values of 3 observational units (7_1 through 7_3) that are within the parent experimental unit, REFID=G.
Row 15:	Shows the value of REFID=R. This REFID refers to the trial set with a SETCD of "SetG", as defined in the TX dataset. LEVEL=1 and LVLDESC="EXPERIMENTAL UNIT/TRIAL SET". TRIAL SET indicates this identifier relates to the entire trial set. EXPERIMENTAL UNIT indicates this identifier received the intervention article, NaN3.
Rows 16-18:	Show the values of 3 observational units (18_1 through 18_3) that are within the parent experimental unit, REFID=R.

Rows 23-25:	Show summary values collected (mean, standard deviation, fold increase) for GTREFID=R that apply to the entire trial set, SetR, as indicated by LEVEL=1 and LVLDESC=TRIAL SET for this REFID in the RELREF dataset.
