I suppose if we knew *how* silver kills bacteria, then we could find out how they can become resistant. I had always thought that bacteria couldn't become resistant because silver doesn't work in the same way as ABX's. Dee

The only silver resistant bacteria we've heard about before were found in mineral deposits where silver was in high concentration in the growth medium. Resistance was quickly lost by future generations of the "bugs" when removed from the silver rich environment. At least a few common types of bacteria were found to behave this way if I remember the stories right.
