564ANTIMICROBIAL ACTIVITIES OF GERANIUM EXTRACT AND SILVER, COPPER NANOPARTICLESThe antimicrobial of silver and copper nanoparticles were recently focused on studied in the literature. In this article five experiments were done to see the effect of silver and copper nanoparticles alone or with Geranium leaf extract on two grams positive and two grams negative bacteria beside Candida albicansas fungi. The effect of both nanoparticles was higher in Pseudomonasaerugenosa and E.coli, while the lower effect was on Streptococcus pyogenes and Bacillus cereus. Silver nanoparticles alone had better effect on Candida albicans growth than other treatments. In our opinion this is the first experiment to be done on the effect of silver and copper Nanoparticles on Iraqi bacterial strains nkalani54@yahoo.comResearch622015Silver and copper Nanoparticles,Bacteria,Fungi,AntimicrobialAssma Gatta,Mokhtar Jawad,Anas Sabah Bahjat,Nabeel k.Al-ani,Ayad M.
