A colleague I trust pointed out that published reports now cite pathogens that are resistant to silver.
The following article explains the mechanism and cross-bacterial transfer of silver resistance genes among bacteria. http://www.wwdmag.com/Coping-with-Resistance-to-Copper-Silver-Disinfection-a rticle2768 At the bottom of the page is list of some known resistances to copper and silver: Escherichia coli bacteria Cu Klebsiella pneumoniae bacteria Cu & Ag Legionella pneumophilia bacteria Cu & Ag Salmonella sp. bacteria Ag Vibrio cholerae bacteria Cu & Ag Candida albicans yeast Cu Saccharomyces cerevisiae yeast Cu & Ag Hartmenella vermiformis protozoa Cu & Ag Tetrahymena pyriformis protozoa Cu & Ag Paramecium sp. protozoa Cu & Ag Amoeba sp. protozoa Cu & Ag My colleague also did a PubMed search on "silver resistance." She found that article 12829274 mentions that in 2003, E. coli strain O157:H7 was found to have silver resistance genes in its genome. I am wondering if we should be cautious about using CS routinely (meaning even when we aren't ill). Or do you think the article is flawed? If so, what are the flaws? Thanks. Nenah
