Viability of S. aureus SH1000 slow-growing and persister cells following exposure to compounds for 24 h. (a) Exponential- and stationary-phase cell viability following exposure to biofilm eradicators at the MBEC or biofilm non-eradicators at 256 mg/L. T₀ is the culture density before the addition of compounds. (b) Cell viability of ciprofloxacin and ampicillin persisters following exposure to compounds at 10× MIC. Results are means of at least three independent determinations and error bars show standard deviations.
