Table 2. Mean bacterial biofilm quantities and LRF values.
Organism | Direct Current | log10 cfu/cm2 | Std. Dev. | LRF |
---|---|---|---|---|
S. aureus | None | 5.88 | 0.45 | 1.20 |
200 μA | 4.68 | 0.78 | ||
S. epidermidis | None | 6.66 | 0.12 | 4.83 |
200 μA | 1.83 | 1.57 | ||
P. aeruginosa | None | 5.85 | 0.04 | 3.49 |
200 μA | 2.36 | 1.04 |
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.
