Integron types, antimicrobial resistance genes, virulence gene profile, alginate production and biofilm formation in Iranian cystic fibrosis Pseudomonas aeruginosa isolates.

Cystic fibrosis (CF) patients commonly suffer from continuous and recurrent lung infections caused by Pseudomonas aeruginosa, the dominant pathogen in CF airways. This study aimed to determine the integron types, gene cassettes, virulence determinants, β-lactam resistance genes, biofilm formation and alginate production in P. aeruginosa isolated from Iranian CF patients. A total of 143 P. aeruginosa isolates were obtained from CF patients....
