[Chronic Pseudomonas aeruginosa airway colonization in cystic fibrosis patients : Prevention concepts].

Pseudomonas aeruginosa (PsA) is a hallmark pathogen of the lung disease in cystic fibrosis (CF) patients. Chronic PsA colonization is a central factor in the course of CF lung disease. PsA contributes considerably to morbidity and mortality, and also has a significant impact on quality of life and the costs of CF treatment. Prevention of chronic colonization has therefore been a major goal in the treatment of CF patients for many years now. In the present article, studies are presented which suggest that prevention of chronic colonization can be achieved. Approaches to prevent chronic PsA colonization are critically evaluated and recommendations for preventative approaches are generated from this discussion.
