FINDINGS: Using strain TA100-hSULT1C2, which expresses human SULT1C2, we optimized the protein content of S9 Mix and the pre-incubation time required to promote metabolic activation in the Ames test. This procedure enabled us to obtain a positive response with ME. C …

To determine the virulence of non-toxigenic variants of virulent strains, we isolated pX01- derivatives of the Vollum 1B strain and the more 'vaccine-resistant' Ames strain which carried pX02 from either Ames or Vollum 1B. The 50% lethal dose (L …
