A mutant, named 11B, hypersusceptible to aminoglycosides, tetracycline, and erythromycin was isolated after Tn501 insertion mutagenesis of Pseudomonas aeruginosa PAO1. Cloning and sequencing experiments showed that 11B was deficient in an, at that time, unknown active efflux system that contains homologs of MexAB. This locus also contained a putative regulatory gene, mexZ, transcribed divergent...

Background: Pseudomonas aeruginosa is the main pathogen responsible for lung destruction in cystic fibrosis, becoming difficult to eradicate chronic infection. Aims: To describe antibiotic resistance among strains of P.aeruginosa isolated from sputa patients with fibrosis. investigate vivo and vitro expression genes related anaerobic growth. Methods: Sputa (in vivo) vitro) 26 were obtained duri...

The majority of cystic fibrosis (CF) patients succumb to a chronic infection of the airway with Pseudomonas aeruginosa. Paradoxically, pathogenic strains are often susceptible to antibiotics, but the infection cannot be eradicated with antimicrobial therapy. We find that in a majority of patients with airway infections, late isolates of P. aeruginosa produce increased levels of drug-tolerant pe...

BACKGROUND Small colony variants (SCVs) are slow-growing bacteria, which often show increased resistance to antibiotics and cause latent or recurrent infections. It is therefore important to understand the mechanisms at the basis of this phenotypic switch. METHODOLOGY/PRINCIPAL FINDINGS One SCV (termed PAO-SCV) was isolated, showing high resistance to gentamicin and to the cephalosporine cefo...

When bacteria evolve resistance against a particular antibiotic, they may simultaneously gain increased sensitivity against a second one. Such collateral sensitivity may be exploited to develop novel, sustainable antibiotic treatment strategies aimed at containing the current, dramatic spread of drug resistance. To date, the presence and molecular basis of collateral sensitivity has only been s...
