eLife assessment
This important study furthers our understanding of the antimicrobial properties of siderophores, and their potential use to battle opportunistic pathogens. The evidence supporting the conclusion is solid, based on rigorous biochemical, growth, and virulence assays. The work would benefit from a more in-depth discussion of the consequences and efficacy of 'siderophore therapy' in more complex communities/environments. The work will be of broad interest to colleagues in the fields of evolutionary ecology, microbiology, and medical sciences.
