Pulmonary Staphylococcus aureus (S. aureus) infections occur early in a high percentage of cystic fibrosis (CF) patients and it is believed that these infections facilitate further colonization of CF lungs with Pseudomonas aeruginosa (P. aeruginosa). Previous studies demonstrated a marked reduction of sphingosine in tracheal and bronchial epithelial cells in CF compared to wild type mice, while ceramide is massively increased in CF mice.
