A Master’s thesis discusses the isolation and identification of E. coli bacteria from children with urinary tract infections and evaluates the effect of zinc nanoparticles.

A Master’s thesis at the College of Education, University of Samarra, titled “Isolation and Identification of E. coli Bacteria from Children with Urinary Tract Infections and Evaluation of the Effect of Zinc Nanoparticles (ZnNPs) Biosynthesized from Cardamom Seeds (Elettaria cardamomum)”, was presented by the student Yusra Mahmoud Ibrahim.

In her thesis, the student aimed to find alternative and effective methods through Nanotechnology, which is known for its properties in inhibiting the growth of disease-causing microbes and its eco-friendliness. Additionally, the goal was to obtain isolates of E. coli from urinary tract infections and identify them through morphological and biochemical methods.

The results demonstrated the possibility of biosynthesizing zinc nanoparticles using a green synthesis method from cardamom seeds (Elettaria cardamomum), and their characteristics were measured using XRD, FE-SEM, AFM, UV, and EXD tests. Furthermore, the biosynthesized zinc nanoparticles showed good inhibitory efficiency against E. coli isolates.
