Figure Legend Snippet: Concentration-dependent change in the humoral inflammatory response following incubation with Escherichia coli ( E. coli ) in the ex vivo whole blood model. a Absolute plasma concentrations of IL-6, IL-8, and MMP9 determined by enzyme-linked immunosorbent assay. b Normalized values and EC 50 curve fit by BuC=0% and 50 000 CFU/ml E. coli= 100%, respectively, for IL-6, IL-8, and MMP9 as indicated by EC 50 (%) on the respective Y-axis. BuC indicates buffer control after 60 min incubation; numbers on the X-axis indicate E. coli bacteria in concentrations of 2000 to 50 000 CFU/ml after 60 min incubation; LPS indicates lipopolysaccharide (LPS) 100 ng/ml after 60 min incubation. Values are shown as median and interquartile range. n =8. Statistical analysis was performed using the Kruskal-Wallis test with Dunn’s post-hoc test, comparing all shown concentrations of E. coli bacteria and 100 ng/ml LPS with BuC. P -values are indicated above the respective data points. ⁎ P <0.05, ⁎⁎ P <0.01, ⁎⁎⁎ P <0.001. CFU. Colony-forming units; IL. Interleukin; MMP9. Matrix metallopeptidase 9.

Figure Legend Snippet: Diagnostic performance for the detection of bacteremia, analyzing the neutrophil phenotype by determining the median fluorescence intensity (MFI) and the cellular response capacity (CRC) in comparison with traditional markers of humoral inflammation (IL-6, IL-8, MMP9). a Comparison of receiver operating characteristic (ROC) at 10,000 CFU/ml Escherichia coli ( E. coli ) with the respective 95% confidence interval (CI) and P -value, and half-maximal effective concentration (EC 50 ) as a function of the E. coli concentration. b Detailed comparison of the EC 50 as a function of the E. coli concentration. c Exemplary comparison of EC 50 curve fit after normalization as indicated by EC 50 (%) on the respective Y-axis to BuC=100% and 50 000 CFU/ml E. coli =0% for the humoral marker IL-6 (the IL-6 values were multiplied by −1 before EC 50 calculation to facilitate comparability with the CRC) and the change in neutrophil phenotype represented by CD11b CRC. BuC indicates buffer control after 60 min incubation; numbers on the X-axis of c indicate E. coli bacteria in concentrations of 2000 to 50 000 CFU/ml after 60 min incubation. Values are shown as median and interquartile range. n =8. Statistical analysis was performed using the Kruskal-Wallis test with Dunn’s post-hoc test, evaluating the EC 50 of IL-8, MMP9, the MFI, and CRC of CD10, CD11b, and CD62L in comparison to the EC 50 of IL-6. P -values are indicated above the respective data points. ⁎ P <0.05. CFU. Colony-forming units; IL. Interleukin; MMP9. Matrix metallopeptidase 9.
