Bacillus cereus.

A mixture of live and heat-killed Bacillus cereus cells simultaneously stained with the cell-permeant SYTO® 59 red-fluorescent nucleic acid stain (Cat. No. S11341) and the cell-impermeant SYTOX® Green nucleic acid stain (Cat. No. S7020), each at a concentration of 5 µM. Bacteria with intact cell membranes stain fluorescent red, whereas bacteria with damaged membranes stain fluorescent green. This maximum-projection image was generated from a series of 10 images taken at 0.2 µm increments through the specimen with a Leica confocal laser-scanning microscope.
