Microbiology Department of Brigham Young University has performed
extensive tests with Collodial Silver to determine controlled
enviornment effects on Bacteria.

Colloidal Silver Testing Results Summary: The following results
suggest that a Colloidal solution is a broad spectrum antimicrobial
agent able to effectively stop the growth of, and in fact kill, a
variety of bacteria.

Staphylococcus Aureus :(Pneumonia, eye infections, skin infections
(boils, impetigo, cellulitis, and post-operative wound infections),
toxic shock syndrome, meningitis, food poisoning, osteomyelitis, and
many others) inhibited @ 2.5 ppm and killed @ 5 ppm. 1/22/99 BYU
Report.

Shigella Boydii: (Bacillary dysentery–characterized by severe cramping
abdominal pain and bloody diarrhea) inhibited @ 1.25 ppm and killed @
2.5 ppm. 1/22/99 BYU Report.

Salmonella Arizona: (Food poisoning, etc.) inhibited @ 2.5 ppm and
killed @ 5 ppm. 1/28/99 BYU Report.

Salmonella Typhimurium: (Food poisoning and enteric fever) inhibited
and killed at a concentration of 2.5 ppm. 6/7/99 BYU Report.

E. coli: (Food poisoning, urinary tract infections, traveler’s
diarrhea, diarrhea in infants, respiratory tract infections, and wound
infections) inhibited and killed @ 2.5 ppm. 1/22/99 BYU Report.

Haemophilus Influenzae:(Otitis media (ear infection), pneumonia,
meningitis, throat and sinus infections (including epiglottitis in
children and sinusitis), and suppurative arthritis in children)
inhibited and killed @ 1.25 ppm. 1/22/99 BYU Report.

Enterobacter aerogenes:( wound infections, urinary tract infections,
bacteremia, and meningitis) inhibited and killed at a concentration of
2.5 ppm. 6/7/99 BYU Report.

Enterobacter cloacae: ( causes ilnesses similar to the E. aerogenes)
inhibited and killed at a concentration of 5 ppm. 6/7/99 BYU Report.

Klebsiella pneumoniae: (lower respiratory tract infections, nosocomial
infections (infections spread in hospitals), urinary tract and wound
infections, and bacteremia) inhibited and killed @ 2.5 ppm. 1/28/99
BYU Report.

Klebsiella oxytoca:(Similar to those infections caused by K.
pneumoniae) inhibited and killed at a concentration of 2.5 ppm. 6/7/99
BYU Report.

Pseudomonas aeruginosa:(severe burn and wound infections, keratitis,
pneumonia, meningitis, nosocomial infections, urinary tract
infections, etc.) inhibited @ 2.5 ppm and killed @ 5 ppm. 1/22/99 BYU
Report.

Streptococcus pneumoniae: (pneumonia, meningitis, sinusitis, otitis
media (ear infection) inhibited @ 2.5 ppm and killed @ 5 ppm. 4/21/99
BYU Report.

Streptococcus pyogenes: (skin infections, upper respiratory infections
(i.e. strep throat) impetigo, hospital-acquired infections, scarlet
fever, etc.) inhibited and killed @ 1.25 ppm. 1/22/99 BYU Report.

Streptococcus faecalis: (Urinary tract infections, endocarditis, wound
infections, etc.) inhibited @ 2.5 ppm and killed @ 5 ppm. 1/22/99 BYU
Report.

Streptococcus mutans: (A major cause dental plaque and tooth decay
etc.) inhibited and killed @ 5 ppm. 2/3/99 BYU Report.

Streptococcus gordonii: (Tooth decay, also implicated in infective
endocarditis-an infection of the heart valves) inhibited and killed @
5 ppm. BYU Report 2/12/99.

This does not even include molds, funguses, etc. Still irrigating with
great results.
