Antibacterial Activity of Zinc Oxide Nano Particles Against Bacteria Isolated from Infants with Urinary Tract Infection

Abstract

This study included the collection of 70 sample of urine from infant aged between (2 days-2 years) divided into 35 sample of healthy children and 35 sample of children suffering from urinary tract infection, Through which get 40 isolated of different types of bacteria. And at different rates ranged between (27 , 12.8 , 7.1 , 5.7 , 4.2 % ) As percentages of the total isolation and (47.5 , 22.5 , 12.5 , 10 , 4.2 %) As percentages of isolation ratios qualitative for E.coli , Proteus mirabilis , Klebsiella Aerogenes, Pseudomonas aeruginosa and Enterococcus Faecalis respectively ,While the number of bacteria in sick children was ( 15, 8, 5, 3, 2 ) isolated for E.coli, Proteus mirabilis, Klebsiella Aerogenes, Pseudomonas aeruginosa and Enterococcus Faecalis respectively with isolation rates (42.85, 22.85, 14.28, 8.57, 5.7 %) Compared with healthy children who were (4) isolated for E.coli and with isolated ratios have (11.42%) and one isolated for each of Proteus mirabilis, Pseudomonas aeruginosa and Enterococcus Faecalis with isolated ratios (2.85 %) for this types respectively, also the preparation of zinc oxide nanoparticles done in Nanotechnology and Advanced Materials Research Center (NAMRC) in university of technology and Prepared of Zinc Oxide NanoParticles were investigated via using Scanning Electron Microscopy (SEM, the VEGA Easy Probe), X-ray powder diffraction (XRD) and antibacterial activity and the results of Zinc Oxide Nano Particles against bacteria explain a bility of it's to inhibition growth of bacteria in different rate of bacteriostatic when used in different concentration.
