The Assessment of Antibacterial effects of CuO Nano- Particles On yersinia rockery

The use of metal oxide nanoparticles can be effective to eliminate the bacterial infections, as an Alternative to antibiotics. In this study, antibacterial properties of nonmaterials of CuO are investigated against yersinia rockery.The aim of this study this research was introducing the properties of the anti-microbial and antibacterial of CuO Nano-particlesThe Nano-particles caused oxidization and destruction of micro-organisms’ membranes by producing free radicals of OH and O ².The anti-bacterial effect of Cu nano-particles on yersinia ruckery bacteria was investigated separately based on the diameter of the preventive region by experiment the small hole and broth media containing the of 0.2, 0.4, 0.6, 0.8 and 1.0 percent of concentrations, respectively.Comparison of the critical and effective concentrations as well as nano-particles’ synthic-mortality were examined with the common antibiotics of oxi-tetra-cycline.The minimum of the Inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) in this media were analyzed.The results of this study showed that CuO nanoparticles exhibited inhibitory effects against gram-negative bacteria.The diameter of CuO preventive region was 6mm and oxi-tetra-cycline was 7mm (1%).Finally, oxi-tetra-cycline anti-biotics was selected as the best alternative for anti-microbial purposes and secondly CuO nano-particles were recommended as an anti-microbial used for anti-infection of culture water and pool walls. This is of importance hygienically and economically.
