infection in cystic fibrosis siblings with different outcomes: Case reports.

Introduction: The clinical relevance of infection in cystic fibrosis (CF) remains controversial. This emerging agent in CF has been associated with increased lung inflammation, more frequent exacerbations and more severe lung disease. We describe a pair of CF siblings chronically colonized by the same multilocus genotype of with different clinical courses, and assess whether this species may have developed any virulence traits and antimicrobial resistance that could have contributed to their singular outcomes.

Performance of MALDI-ToF MS for species identification of Burkholderia cepacia complex clinical isolates.

We evaluated the performance of matrix-assisted laser desorption ionization-time of flight (MALDI-ToF) for identification of Bcc species compared with that of recA sequencing. MALDI-ToF was able of identifying 100% of Bcc isolates at the genus level, but 23.1% of Bcc isolates tested were not correctly identified at the species level.

First report of Paenibacillus cineris from a patient with cystic fibrosis.

We describe the recovery of Paenibacillus cineris from a Brazilian cystic fibrosis (CF) patient. Paenibacillus spp. are mainly environmental organisms.
