Calibration curves describing the relationship between the concentration of the bacteria in the wells and the rate of resazurin metabolization. Depicted results are T2000 values compiled from the three independent experiments for both E. coli and E. faecalis. Dotted lines depict confidence intervals with a confidence level of 95%. T2000 values under the LOQ level (i.e. 10³ CFU mL⁻¹) are not depicted in the graph
