Table 1. Fold reduction in viability of bacteria exposed to bilirubin.
Bacteria | Strain | Fold Reduction | % Std. Dev. |
E. coli | 86-24 | 1.0 | 17% |
E. faecalis | OG1RF | 610,000 | 54% |
B. cereus | 1048 | 131,111 | 43% |
S. aureus | MW2 | 57 | 104% |
Mid-log phase bacteria were exposed to 200 µM bilirubin and plated to determine CFUs. Fold reduction was calculated by the quantity of bacteria unexposed to bilirubin divided by the quantity present when exposed to bilirubin, n = 3.
