Respiratory bacterial infections in cystic fibrosis

Bacterial respiratory infections are the main cause of morbidity and mortality in patients with cystic fibrosis (CF). Pseudomonas aeruginosa remains the main pathogen in adults, but other Gram-negative bacteria such as Achromobacter xylosoxidans and Stenotrophomonas maltophilia as well as nontuberculous mycobacteria have been shown to play an important role in the lung disease. The purpose of this review is to summarize the knowledge on disease and treatment of infection with CF-related pathogens.
