The work presented sought to identify siderophore genes in quercetin-resistant Pseudomonas aeruginosa. Bacterial isolates from swab samples taken from patients suffering from complicated wound infections.

A total of 200 swab samples were collected from attending patients. Compared to patients who are male (41%), the majority of patients (59%) were female. The patients have provided swab samples for sterile swab transport, displaying signs of a wound infection. The samples were cultivated on nutrient agar, blood agar, MacConkey agar, and cetrimide agar, and they were incubated for 24 h at 37°C.

The results were recorded by isolating gram-negative bacteria and observing developed colonies after identifying n = 59 (29.5%) isolates from 200 clinical samples as P. aeruginosa . The plcN and exoS genes were found in the isolates chosen. In this study, n = 10 (100%) isolates tested positive for the 16s rRNA housekeeping gene, n = 8 (80%) of isolates tested positive for the plcN gene, and n = 8 (80%) isolates tested positive for the exoS gene.

The high prevalence of plcN and exoS gene detection in quercetin-resistant strains may be the primary reason for the high virulence factor in connection with quercetin resistance.
