DNA Fingerprinting of the Local Pathogenic Bacteria Which Treated with Copper

Abstract

Copper (Cu) is an essential trace element for all aerobic organisms. It functions as a cofactor in enzymes that catalyze a wide variety of redox reactions due to its ability to cycle between two oxidation states, Cu(I) and Cu(II). This same redox property of copper has the potential to cause toxicity if copper homeostasis is not maintained. Studies suggest that the toxic properties of copper are harnessed by the innate immune system of the host to kill bacteria. The aim of this research is show the DNA fingerprinting of two local pathogenic bacteria(Staphlococcus aureus isolated from body fluid and  E.coli isolated from urine) which treated with Copper  to clarify the role of copper's antibacterial activity against bacterial species could be utilized in health care facilities and in food processing plants.
