Evaluation of the relationship between quorum sensing system genes and antibiotic resistance in isolated Pseudomonas aeruginosa from cystic fibrosis patients

The study specified that more than half of the <i>P. aeruginosa</i> strains exhibited resistance to five antibiotic classes, and effective antibiotics against <i>P. aeruginosa</i> were colistin, meropenem, ciprofloxacin, piperacillin/tazobactam, and cefotaxime. A noteworthy correlation was identified between MDR and XDR strains and the existence of QS genes in the strains.
