Indole-Acetic Acid Impairs Pseudomonas aeruginosa Virulence and Alters Lung Infection in Mice. [PDF]

Microbiologyopen
Screening for anti‐virulence activity exerted by tryptophan catabolites on laboratory and clinical strains of Pseudomonas aeruginosa showed that Indoleacetic acid (IAA) inhibits motility and pigment production, downregulates PQS gene expression, while increases oxidative stress sensitivity.
