The effectiveness of SYTOX Green nucleic acid stain for measuring
bacterial viability was tested on starved populations of Escherichia coli and Salmonella typhimurium.
This stain underestimates the fraction of dead cells within starved
populations containing cells with damaged nucleic acids or membranes.
Its application to natural samples should be considered with caution.
