This study identifies CsrA as a global regulator of carbon preference and gut colonization in Acinetobacter baumannii, revealing its role in repressing arginine/ornithine catabolism and enhancing competitive fitness.

This study identifies AstR as a regulator of ornithine catabolism in Acinetobacter baumannii, essential for gut colonization by enabling competition with the microbiota.

This study shows that A. baumannii uses ornithine to compete with gut microbiota and persist in mice, with dietary ornithine promoting its carriage.

This study identifies DcaP-family porins as essential for carboxylic acid utilization and infection in A. baumannii, showing functional redundancy and validating their potential as therapeutic targets.
