Page History

This is an example showing trial design and results from the in vitro bacterial reverse mutation test of an example study, Study #8325064. This bacterial reverse mutation test uses four different amino acid-requiring strains of Salmonella typhimurium (S. typhimurium) and one strain of Escherichia coli (E. coli) to detect point mutations, which involve substitution, addition or deletion of one or a few DNA base pairs.

A simplified image of the test procedure is shown above.

In this example, the Trial Summary dataset, ts.xpt, includes many informational fields that may provide context at the study level, for Study 8325064. Also, TSGRPID has been used to link records (name, location, country) related to the test facility (TSGRPID = 1) and records related to the Test Site (TSGRPID = 2). The Study Director is associated with the Test Facility and the Principal Investigator is associated with the Test Site. Finally, the Primary Treatment CAS Registry Number is not known and this is recorded as an empty TSVAL and UNKNOWN in the corresponding TSVALNF.

Rows 1-2:	Show two records for TSPARMCD = "GLPTYP", using TSSEQ to indicate multiple records, since both GLP Types apply for this example study.
Rows 9-12:	Show that TSGRPID has been used to link records (name, location, country) related to the test facility (TSGRPID = 1). The Study Director is associated with the Test Facility.
Rows 18-24:	Show that this example study includes two different species of bacteria and a total of five strains.
Rows 18-22:	Show that TSGRPID (TSGRPID = 2) has been used to link the information for one species (Salmonella) with four different strains that are tested in this example study.
Rows 23-24:	Show that TSGRPID (TSGRPID = 3) has been used to link the information for one species (Escherichia coli) with the strain that is tested in this example study.

This example trial set dataset, tx.xpt, shows information about the test conditions for SetA and SetR in this example study. For brevity, this does not show information for SetF, SetG, or any other sets. A fully formed tx.xpt for this example study would include information about the test conditions for all sets.

Observational Unit Identifiers (OBUIDs) are defined by the sponsor to uniquely identify the observational unit within an experimental unit. In this example the sponsor chose to define the EUIDs based on trial sets (e.g., F) and OBUIDs based on the position of the tube in one of multiple exposure/incubation plates (e.g, 6_1 for plate 6, position 1).
