Quоrum sensing аllоws аn entire pоpulаtion of bacteria to carry out a coordinated activity once the population reaches a certain size. To test the hypothesis that toxin secretion in S. aureus is dependent on quorum sensing, you examine mutants that are known to block two separate quorum-sensing signal transduction pathways: the agr pathway (Accessory Gene Regulator) and the TRAP pathway (TRAns locon associated Protein). You use completely normal ("wild-type") cells as a control. You also decide to examine the ztr- mutant (Zipper-like Transcriptional Regulator) as an additional control, since this mutant is known not to be involved in quorum sensing, and you wish to test for an effect specific to quorum-sensing mutations. For each mutant, you grow cultures to a standardized high density, measure the amount of toxin they produce, and compare them to the wild-type control cells. Results are shown below.
