[Current microbiological data on lower respiratory tract infection in cystic fibrosis. Part I: Isolated microorganisms and their clinical significance].
Cystic fibrosis (CF) is a disease that degrades the local defense mechanisms of the lower respiratory tract. As a result, patients develop recurrent infections that progressively deteriorates antiinfection defenses and represent the major cause of mortality. A hallmark of those infections is the diversity of microorganisms isolated from broncho-alveolar lavage or sputum. ⋯ Hypermutation of P. aeruginosa--the most common species isolated from patients with CF, is the essential factor in the development of multi-resistance to antibiotics. As P. aeruginosa, B. cenocepacia is a virulent species that cause infections with poor prognosis. Microorganisms with secondary role (H. influenzae, S. maltophilia, atypical Mycobacteria, Aspergillus spp) whose clinical significance has not been clarified yet, require further studies.
