Fig. 2. The receiver operating characteristic (ROC) curves for the biomarkers evaluated in the present study. (a) ROC for predicting Gram negative bacteremia. (b) ROC for predicting Gram positive bacteremia. AUC, area under the curve; hsCRP, high sensitivity C-reactive protein; BUN, blood urea nitrogen

Fig. 3. Residual biofilm percentage after treatment of study detergents. The percentage OD₆₂₀ after treatment divided by baseline OD₆₂₀ before detergent treatment was expressed in gray scale with shaded box for the corresponding range. The shade and biofilm removal of each well were inversely correlated. The study detergents included two enzymatic cleaners Empower^TM (Metrex, Orange, CA), Cidezyme^TM (Johnson and Johnson Medical Inc, Arlington, TX), one non-enzymatic cleaner Matrix mint^TM (Whiteley Medical, Sydney, Australia). A chlorine bleach Yuhanrox^TM Regular (Yuhanclorox, Seoul, Korea) was also tested as a control. Abbreviations: DW, distilled water; RT, room temperature.

Fig. 1. Quantification of biofilm formation of each strains among gram-negative rods (A) and gram-positive cocci and yeasts (B) using measuring optical density of crystal violet stained biomass at 620 nm. The standard errors are expressed as error bars. The strains marked with asterisks are submitted to the evaluation of biofilm removal. Type strain names were shaded and the strains derived from clinical isolates were given names starting with AMC.

Fig. 3. The time to positivity (TTP) of aerobic and anaerobic bottles among six most frequent organisms. Each of the white and black arrow heads denoted T50 of aerobic bottles and anaerobic bottles, respectively. The TTP for P. aeruginosa displayed only for aerobic bottles. CNS, coagulase-negative staphylococci; T50, median time-to-positivity.
