Diffusion and Characterization of Pseudomonas aeruginosa Aminoglycoside Resistance in an Italian Regional Cystic Fibrosis Centre

Aims Extensively-drug-resistant Pseudomonas aeruginosa constitutes a serious threat to patients suffering from Cystic Fibrosis (CF). In these patients, P. aeruginosa lung infection is commonly treated with aminoglycosides, but treatments are largely unsuccessful due a variety of resistance mechanisms. Here we investigate the prevalence of resistance to gentamicin, amikacin and tobramycin and the main aminoglycoside resistance genes found in P. aeruginosa strains isolated at a regional CF centre.
