Pneumonia due to Bordetella bronchiseptica in a cystic fibrosis patient: 16S rRNA sequencing for diagnosis confirmation.

Bordetella bronchiseptica was identified as an unusual etiologic agent of pulmonary recurrent exacerbations and pneumonia in a cystic fibrosis (CF) patient by utilizing a 16S rRNA molecular kit in our hospital's clinical laboratory. This method appears to be a useful approach for identifying new emerging CF pathogens when discrepancies exist between phenotypical tests.
