In chronic CF lung infections, which organism is known for biofilm formation?

Biofilm formation is a key reason chronic infections take hold in the cystic fibrosis (CF) lung. The organism that is most characteristically associated with this in CF is Pseudomonas aeruginosa. In the CF airway, Pseudomonas often shifts to a mucoid phenotype that overproduces alginate, creating a thick, protective biofilm encasing bacterial microcolonies. This biofilm acts like a shield, making antibiotics harder to reach and helping the bacteria withstand immune attack, which explains why Pseudomonas infections become chronic and difficult to eradicate. While other bacteria can form biofilms, the persistent, mucoid biofilm formation by Pseudomonas aeruginosa is the classic feature of chronic CF lung infections and a major driver of ongoing inflammation and treatment challenges.
