Fraction of persister, viable but non-culturable, susceptible lysed, and susceptible non lysed cells

Ampicillin concentration dependence of the fraction of VBNC, persister, susceptible non lysed cells, and lysed cells. Persister fractions were measured via both our newly developed single-cell approach and the standard persister assay based on colony forming units (CFU) measurements. However, the CFU method does not allow measuring the fraction of VBNC, susceptible non lysed cells, and lysed cells.
