The Department of Biology Holds a Master’s Student Seminar on the Study of the Effect of Nanocomposites on Pseudomonas Aeruginosa Bacteria Isolated from Burns
As part of the series of scientific activities held by the Department of Biology, a seminar was held for master’s student (Malik Ahmed Aboud), under the supervision of (Prof. Dr. Ashwaq Kazim Obaid), entitled “Studying the Effect of Nanoparticles on Pseudomonas aeruginosa Bacteria Isolated from Burns.” This seminar aimed to study the effect of silver nanoparticles (AgNPs) on Pseudomonas aeruginosa bacteria isolated from wounds and burns. This pathogenic bacterium is known for its high resistance to antibiotics and causes chronic and serious infections. A bio-preparation method was used to prepare these particles using a plant extract, and their physical and chemical properties were verified using multiple techniques such as UV-Vis, SEM, and FTIR. The study results also demonstrated that silver nanoparticles are clearly effective in inhibiting bacterial growth and reducing the production of virulence factors such as exoenzymes and toxic proteins, in a concentration-dependent manner. The particles also proved effective in penetrating bacterial cell membranes and destroying their biological structures, making them a promising alternative to traditional antibiotics against resistant strains, with potential use in medical and pharmaceutical applications.
