Dear Mr. Rasplicka:

This will acknowledge receipt of your FAX of May 5, 1998 asking me to repeat the test against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus using this technique of rubbing the Ozonated Olive Oil on the Mueller Hinton Plate rather than expecting the Ozonated Olive Oil to diffuse into the Mueller Hinton Medium.

The Ozonated Olive Oil was tested against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa as outlined in the October, 1996 Letter to the Editor to Townsend Letter for Doctors & Patients entitled "Not All Colloidal Silver Products are Created Equal!", only it was rubbed on the Mueller Hinton Medium. The results of the Ozonated Olive Oil, antibiotic discs and bacteria are as follows:

	Antibiotics:
Bacteria	Ampicillin	Cephalothin	Ozonated Olive Oil
Escherichia coli	18 mm	19 mm	Growth Repeated twice
Normal range	16 - 22 mm	15 - 21 mm

	Antibiotics:
Bacteria	Carbenicillin	Ozonated Olive Oil
Pseudomonas aeruginosa	17 mm	No Growth One Test
Normal range	18 - 24 mm

	Antibiotics:
Bacteria	Ampicillin	Oxacillin	Ozonated Olive Oil
Staphylococcus aureus	30 mm	20 mm	No Growth One Test
Normal range	27 - 35 mm	18 - 24mm

Sincerely

J. P. Kilbourn, Ph. D.
Laboratory Director
