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.
