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.

The paper identifies a SNP in uppS that synergizes with mlaF deletion to increase susceptibility to membrane stress and antibiotics in A. baumannii.
