  2. recreate the data table - clean up, add "S" to the first set A

This is an example showing trial design and results from the in vitro bacterial reverse mutation test of Study #8325064. 

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.

  • How do we handle "toxic, no revertant colonies"?  (LAK will add 6 records with GTSTAT = NOT DONE, GTREASND = "TOO MUCH CYTOTOXICITY,"
  • Condition of background bacterial lawn?  Slight thinning, Very thin? - refer to SEND team's marked-up table.
    • new Test code of Cytotoxicity with GTORRES = S, V (controlled terms)
    • Each plate we would have one result record for Revertent count and another for the lawn evaluation (NORMAL, SLIGHT THINNING, VERY THIN)
  • When "-" in Mean, Std Dev, Fold Inc - refer to SEND team's marked-up table (GTSTAT = NOT DONE; variety of REASND)
