Prof. Dr. Rabee’ Mohsen Hassani (University of Babylon / College of Medicine) – Member & Supervisor Study Overview and Key Findings The study introduced an innovative approach by using Pseudomonas aeruginosa to biologically synthesize silver nanoparticles and evaluate their effects on virulence genes and carbapenemase resistance in Klebsiella pneumoniae. The biosynthesized silver nanoparticles demonstrated a strong ability to inhibit the growth of Klebsiella pneumoniae and had a direct impact on both virulence genes and carbapenemase-related resistance. A total of 100 isolates were isolated and confirmed with a 99.7% match using the VITEK-2 system, with absolute resistance (100%) recorded against several conventional antibiotics. The results also showed that combining nanoparticles with antibiotics significantly enhanced the efficacy of beta-lactams and carbapenems.
