the test used in the article someone posted was the same method as this, and *they* reported that all organisms were killed. How come? dee

I gave some Colloidal Silver solution to an old friend of mine that I
met at a reunion who happens to be a microbiologist.  I happened to
have some CS with me and he was intrigued with it and said he was
willing to do some tests of it's effectivity.  I have included his
response below.  If anyone has some suggestions on how to test it
properly, please let me know.  Also, any relevant reference as well.

He says:

"I tested the colloidal silver solution using the methodology that we
use in the lab to test standardized antibiotics.  I created a lawn of
bacteria of known density on agar plates, and then placed a drop of
the silver solution in the center of the plate, which then diffused
through the bacteria and into the agar medium.   None of the 9 most
commonly encountered organisms showed any zone of inhibition.  The
organisms I used in this experiment were E. coli, E. coli (ESBL),
Staph. aureus and MRSA, Enterococcus, Pseudomonas aeruginosa,
Moraxella cattarrhalis, Group A beta Strep, and Streptococcus
pneumoniae.
