Microbes tested: Staphylococcus epidermidis, Staphylococcus aureus and Enterococcus faecalis


[ Staphylococcus Aureues, example only ]

Results: Reduction of population counts from >10 million to undetectable in four minutes of exposure

Microbes Tested: Salmonella typhimurium and Pseudomonas aeruginosa


[ Example of Pseudomonas aeruginosa ]

Results: Reduction of population counts from >10 million to undetectable in four minutes of exposure

Microbe Tested: Candida albicans


[ Example of Candida albicans ]

Results: Reduction of population counts from >1 billion to undetectable in two minutes.

Details of the Study

Staphyloccus aureus ATCC12600

Two concentrations of isolated silver were used, one 15 PPM isolated colloidal silver and one 30 PPM isolated colloidal silver. The 30 PPM colloidal silver achieved results markedly faster, although both formulations achieved the desired results within four minutes:

The in-vitro lab results conclusively demonstrate that a high quality isolated colloidal silver product is remarkably effective in concentrations of both 15 PPM and 30 PPM against Staph Aureus. A greater concentration demonstrated faster action, however, the results in the first four minutes dropped population counts to nearly non-existant levels with both formulations.

Pseudomonas aeruginosa PAO

Two concentrations of isolated silver were used, one 15 PPM isolated colloidal silver and one 30 PPM isolated colloidal silver. The 30 PPM colloidal silver achieved results markedly faster, although both formulations achieved the desired results within four minutes:

The in-vitro lab results conclusively demonstrate that a high quality isolated colloidal silver product is remarkably effective in a concentration 30 PPM ( likely 15 PPM as well ) against Candida albicans. The results in the first two minutes dropped population counts to nearly non-existant levels.
