    Studysummary This study found that biliverdin beta and delta, metabolites of heme, play a critical role in <i>Pseudomonas aeruginosa</i> iron acquisition and cooperative behaviors, which are crucial for the bacterium's long-term infection in cystic fibrosis patients, suggesting potential targets for new therapies.
