One of the first pathogens which can be isolated from the airways of cystic fibrosis (CF) patients is Staphylococcus aureus, which often persists in this hostile environment for many months or even years. The increase in infections due to the methicillin-resistant S. aureus (MRSA) worldwide and even more the emergence of community-acquired MRSA, which differ from nosocomial MRSA by lack of multiresistance and carriage of a phage-encoded toxin, Panton-Valentine leukocidin, attracts new attention to the epidemiology, pathogenesis, and impact of S. aureus in the background of CF. In this review, recent data and studies will be reported and discussed to give an overview of the latest research.

Staphylococcus aureus is a common and significant pathogen in cystic fibrosis. We sought to determine if quantitative PCR (qPCR) and 16S rRNA gene sequencing could provide a rapid, culture-independent...
Methicillin-resistant Staphylococcus aureus (MRSA) infects ∼25% of patients with cystic fibrosis (CF) in the United States. We hypothesized that health-related outcomes differed between healthcare-a...
Lung transplantation is an intervention that improves survival for adult patients with cystic fibrosis (CF). Some patients with CF are never referred for lung transplant evaluation despite meeting phy...
Exacerbations associated with chronic lung infection with Pseudomonas aeruginosa are a major contributor to morbidity, mortality and premature death in cystic fibrosis. Such exacerbations are treated ...
We describe the clinical characteristics and epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) in children with cystic fibrosis (CF) from the U.S. CF center with the highest MRSA prev...
Staphylococcus aureus is not only one of the first pathogens infecting the airways of cystic fibrosis (CF) patients, but also a highly prevalent microorganism (>60% of all CF patients; Eur...
Staphylococcus aureus nasal carriage is a major risk factor of infection with this bacterium. To our best knowledge, Staphylococcus aureus colonization of the posterior nasal cavity is sti...
The purpose of this study is to test the hypothesis that early viral infections alter the bacterial flora and inflammatory profile in the airway and accelerate progression of pulmonary dis...
To establish the clinical test performance characteristics of sensitivity, specificity and predictive values for direct detection of nasal Staphylococcus aureus colonization against clinic...
The purpose of this study is to better define risk factors preceding first isolation of Pseudomonas aeruginosa (Pa) from respiratory cultures in cystic fibrosis (CF) lung disease and to be...
An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.
A strain of Staphylococcus aureus that is non-susceptible to the action of METHICILLIN. The mechanism of resistance usually involves modification of normal or the presence of acquired PENICILLIN BINDING PROTEINS.
A chloride channel that regulates secretion in many exocrine tissues. Abnormalities in the CFTR gene have been shown to cause cystic fibrosis. (Hum Genet 1994;93(4):364-8)
A rehabilitation therapy for removal of copious mucus secretion from the lung of patients with diseases such as CHRONIC BRONCHITIS; BRONCHIECTASIS; PULMONARY ABSCESS; or CYSTIC FIBROSIS. The patient's head is placed in a downward incline (so the TRACHEA is inferior to the affected area) for 15- to 20-minute sessions.
A strain of mice widely studied as a model for cystic fibrosis. These mice are generated from embryonic stem cells in which the CFTR (cystic fibrosis transmembrane conductance regulator) gene is inactivated by gene targeting. As a result, all mice have one copy of this altered gene in all their tissues. Mice homozygous for the disrupted gene exhibit many features common to young cystic fibrosis patients, including failure to thrive, meconium ileus, and alteration of mucous and serous glands.
