Transmissible strains of Pseudomonas aeruginosa in cystic fibrosis lung infections.
Pseudomonas aeruginosa chronic lung infections are the major cause of morbidity and mortality associated with cystic fibrosis. For many years, the consensus was that cystic fibrosis patients acquire P. aeruginosa from the environment, and hence harbour their own individual clones. However, in the past 15 yrs the emergence of transmissible strains, in some cases associated with greater morbidity...
متن کاملEmergence of Pseudomonas aeruginosa strains producing high levels of persister cells in patients with cystic fibrosis.
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...
متن کاملAntibiotic Susceptibility of Pseudomonas Aeruginosa Isolated from Cystic Fibrosis Patients
Abstract Background and Objective: Cystic fibrosis (CF) is an autosomal recessive genetic disease and Pseudomonas aeruginosa is one of the most common bacteria colonized in CF patients. Growing resistance of this bacterium to antibiotics now a day is a challenge of controlling infection in CF patient. In this study colonization of CF patients with Pseudomonas aeruginosa and antibiotic suscep...
متن کاملAuxotrophy of Pseudomonas aeruginosa in cystic fibrosis.
Seventy-four of 403 (18.4%) sputum isolates of Pseudomonas aeruginosa from 49 of 136 (36.0%) adults with cystic fibrosis (CF) were auxotrophic mutants. Two of 11 (18.2%) isolates of P. aeruginosa taken from patients with non-CF bronchiectasis were also auxotrophic. All 99 strains taken from non-bronchiectatic sources were prototrophic. Forty-six of 55 (83.6%) CF auxotrophs required one or more ...
متن کاملEradication of Pseudomonas aeruginosa in cystic fibrosis.
We read with interest the recently published article by TACCETTI et al. [1] in the European Respiratory Journal and the accompanying editorial by JONES [2]. TACETTI et al. [1] report on their experience with early eradication therapy against Pseudomonas aeruginosa (PA) in cystic fibrosis (CF), concluding that this treatment exerts a number of beneficial effects and is also cost-effective. Howev...
