Table 1. Mean bacterial biofilm quantities and LRF values at 24 hours (n = 3 for all samples).

Organism	Direct Current	log10 cfu/cm2	Std. Dev.	LRF
S. aureus	None	5.37	0.15	2.20
	200 μA	3.17	0.71
S. epidermidis	None	7.09	0.19	3.20
	200 μA	3.89	0.75
P. aeruginosa	None	6.92	0.31	2.04
	200 μA	4.88	0.35

The mean bacterial quantities were calculated following exposure to either no current or 200 μA DC after 24 hours (n = 3 for all samples). Std. Dev., standard deviation.
