Fifty microliters of the bacteria
C600 were spread onto separate petri dishes and then 10 mircoliters of either
Kanamycin or colloidal silver which were pipetted onto the plates to test the
effectiveness of each antibiotic. When colloidal silver was paired
against Kanamycin, the results were obvious that Kanamycin proved much more
effective against bacteria. On the plates where colloidal silver were spread
against the bacteria, the plates were all cloudy, despite the amount of silver
spread. There were also numerous little colonies around the area the silver was
spread. Kanamycin, however, left a clear area with only a few little colonies
around the outside of the area that Kanamcyin was spread.
The fruit fly experiment was to determine whether or not colloidal silver was toxic to fruit flies. In order to test this, flies were cultured with water or colloidal silver mixed with their food in two respective tubes. First off, it is important to know that from the vial containing food and water, 7 out of 20 flies did not wake up. From the vial with colloidal silver and food, 6 out of 20 flies did not wake up. After the experiment was acted out with the plates and culturing of the mixture of homogenized bug and water, the average number of bacteria colonies of water treated flies and colloidal silver flies were calculated:
Column one is the average of bacteria of Colloidal Silver treated flies. The average of 951.6 colonies. Column two is for the non-treated flies with an average number of 4767.6 colonies.
Fifty mircoliters of C600 were again spread on petri dishes. Then 10 microliters of Ampicillin and Kanamycin were pipetted into the center of their respective dishes. The diluted formulas of the antibiotics were then pipetted onto dishes to compare with the full strength as well as the dish with nothing but water. Ampicillin clearly worked the best with a large ring in the diameter of the killing. Both dishes where full-strength Kanamycin had been used had about a diameter of 2.5 cm. Even the dishes of diluted Kanamycin had a 2.5 cm diameter of area where there was no evidence of growth of bacteria. The full-strength Ampicillin, however, had a diameter of about 3.5 cm.|

In the dishes with diluted Ampicillin there were 3 cm of no growth, so it was still a larger area of no growth. Colloidal Silver was a bit disappointing. There was a faint circle where there was a little growth, but still growth. There was only a faint ring around the circle where there was an area of no growth. And this ring was about .2 cm across. Both dishes of full strength colloidal silver yielded these results. The control that had nothing but water dropped into it and there was a faint, indented circle that was about 1.5 cm in diameter because of the force with which the water hit the surface of the petri dish.
