Fig. 1From: The agr quorum sensing system in Staphylococcus aureus cells mediates death of sub-populationagr and RNAIII influence cell viability. a Cultures of WT, ΔagrA and ΔRNAIII mutant were stained with PI and TO and the percentage of dead cells determined by flowcytometry (An asterix indicates a p-value of < 0.05 when compared to WT by Student’s T-test). b The percentage of dead cells was determined by staining and flowcytometry at various time points after inoculation of WT cells carrying either vector (pTXΔ) or the RNA overproducing plasmid (pTXΔRNAIII). Bars represent the mean and the standard deviation from biological triplicatesBack to article page
