Master's Thesis at the University of Basrah Investigates Genetic Identification of Pseudomonas aeruginosa

A master's thesis at the College of Veterinary Medicine, University of Basrah, focused on the genetic identification of Pseudomonas aeruginosa responsible for otitis (ear infections) in both cats and humans, as well as its resistance to various antibiotics.

The thesis, presented by Shahnaz Faleh Badr, aimed to isolate and identify P. aeruginosa from ear infection cases in both animals and humans, and to determine resistance patterns by detecting specific virulence genes.

The research involved the analysis of 150 human and animal samples, preparation of a silver nitrate nanoparticle extract, and investigation of its effect on P. aeruginosa isolates, including their ability to produce biofilms through the detection of biofilm-related genes.

The study concluded that the nanoparticle extract had a significant inhibitory effect on the bacterial isolates. It also revealed shared virulence genes between human and animal isolates, as well as antibiotic-resistant strains, and recorded 15 new strains of the bacterium.
