“Buzz Kill” — The Discovery Files

Washington State University researchers for the first time have discovered how electrical stimulation works for the treatment of bacterial infections, paving the way for a viable alternative to medicinal antibiotics. The researchers passed an electric current over a film of bacteria and in 24 hours killed almost all of a multi-drug resistant bacterium that is often present in difficult-to-treat infections. The remaining bacterial population was 1/10,000th of its original size. The researchers also tested the method on pig tissue, where it killed most of the bacteria and did not damage surrounding tissue.
