This research aimed to isolate fluoroquinolone-resistant <i>P. aeruginosa</i> from patients at Aleppo University Hospital, assess the prevalence of fluoroquinolone resistance, confirm molecular identity, identify plasmid-associated resistance genes, and investigate virulence factors.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>A total of 430 samples were collected from patients and cultured on selective media for identification.

These strains exhibited complete resistance to penicillins and all four generations of cephalosporins while remaining 100% sensitive to colistin. Notably, both hemolysin and gelatinase production rates were found to be 100%, and 48.2% of the isolates formed strong biofilms. The <i>aac(6′)-Ib</i> gene was present in 72.4% of the isolates, the <i>qnrS</i> gene in 44.8%, and the <i>qnrB</i> gene in 13.7%. Additionally, 37.8% of the isolates contained two types of resistance genes, while 62% had one type. Importantly, all resistant isolates (100%) possessed at least four virulence factors.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>The findings indicate a prevalence of plasmid-associated fluoroquinolone resistance genes in the studied isolates.
