Dear Sir:*
This is to inform you that we have received a sample (12 ml) of your
colloidal silver (1,500 ppm)
preparation and have evaluated its effectiveness in a preliminary pilot
study against Lyme disease
spirochete, Borrelia burgdorferi (B31) and against the relapsing fever
agent, B. Hermsii (HS-1).*
In both tests, BSK cultured spirochetes were treated with 150 and 15 ppm
of colloidal silver. When
examined 24 hours later, none of the treated cultures contained live
spirochetes. Few spirochetes, all
dead, were observed at 48 hours.
Additional in vitro and in vivo studies are in progress and will be
reported as soon as results become
available.
Sincerely yours,
Willy Burgdorfer, Ph.D.

Preliminary studies on your silver preparation (1500 ppm) show it to be
effective in inhibiting and killing
strains of Candida albicans and Cryptococcus neoformans in-vitro.
Four strains of C. Neoformans were tested and they were killed by the
preparation at 150-300 ppm. The
growth of these strains were inhibited at a concentration as low as 0.3
ppm.
Three strains of C. Albicans were tested and they were killed by the
preparation at between 46 and 93
ppm. Growth was inhibited at between 0.7 and 1.4 ppm.
Additional studies should be done to evaluate in-vivo effectively.
Sincerely,
Helen R. Buckley, Ph.D.
