Thank you for the additional information and the balanced perspective.

Devour <mdev...@eskimo.com> Subject: Re: CS>Silver resistant bacteria To: silver-list@eskimo.com Date: Sunday, July 20, 2008, 5:36 PM I agree it is quite interesting, Michael. 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. If at least a few bacteria pathogenic in humans turn out to have this ability as well, *and* it can be turned on by the kind of exposure to silver that occurs with routine CS use, then this can become a problem. I suspect (and hope!) we're not on the verge of wholesale silver resistance of run-of-the-mill bacteria in everyday life. Not if ongoing, mult-generational exposure is needed to turn on that defense mechanism, and removal from the silver-rich environment breaks the cycle. In a word, I won't panic yet. Worth watching, definitely. Thanks for the heads-up, Trem. Be well, Mike D.
