Incubation time required to reach O.D.630 nm = 0.035 following SST-IMS of Y. pestis blood cultures. Y. pestis EV76 blood cultures at various initial concentrations were subjected to the SST-IMS procedure. Aliquots of 100 μl of the SST-IMS outputs from each blood culture were plated in 6 replicates in microtiter plates. The microtiter plates were incubated in a plate reader for 48 h at 28°C in ambient air, and the absorbance at O.D.630 nm was read at 1-h intervals until reaching 0.035. Linear regression of log concentration versus time yielded the following prediction equation: Time (h) = -6.1926x + 52.311.
