Genetic Concordance of Staphylococcus aureus From Oropharyngeal and Sputum Cultures in People With Cystic Fibrosis.

Background: People with cystic fibrosis (CF) may not expectorate sputum at young ages or after they receive CFTR modulators. While oropharyngeal swabs are commonly used to test for lower airway pathogens, it is unknown whether Staphylococcus aureus from the oropharynx matches the strain(s) infecting the lungs. Our goal was to determine whether oropharyngeal and sputum isolates of S.

Parallel evolution of linezolid-resistant in patients with cystic fibrosis.

Linezolid is an antibiotic used to treat serious infections. Resistance to linezolid is considered rare but could emerge with repeated dosing. We recently reported widespread prescription of linezolid for a cohort of patients with cystic fibrosis (CF).
