Ttom row, confocal fluorescence microscopy images with the bacterial populations imaged in row three. Appropriate, monitoring of BRcell subpopulation utilizing a Pica-yfp S. aureus labeled strain. Left, monitoring of DRcell subpopulation using a Ppsma-yfp S. aureus labeled strain. Magnification, 100X. The fluorescence signal is shown in green. Bar = 20 mm.

When the agr bimodal switch is activated and BRcells and DRcells differentiate, subpopulation size is modulated by other extracellular cues that impact bimodal switch activity. We report that extracellular Mg2+ is incorporated into the bacterial cell w.
