Background; Electrical stimulation has been used as a modality for many years for wound healing. One of the mechanisms proposed for why it works is that electrical stimulation is believed to be bacteria static. However, early studies making this claim used much greater than normal stimulation voltages and currents. Methods and procedures; In the present investigation, 3 types of bacteria, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus were examined with physiological levels of AC (5 and 20 ma) and DC electrical stimulation to see if these same currents that traverse through tissue during normal electrical stimulation for wound treatment could impair bacterial growth. Results; DC micro current did not alter bacteria growth for any of the three bacteria studied. Pseudomonas aeruginosa showed significantly reduced growth with both (5 and 20 ma) AC current intensities (p<0.05)>
