is a multidrug-resistant nosocomial pathogen. We showed previously that thiostrepton (TS), a Gram-positive thiopeptide antibiotic, is imported via pyoverdine receptors and synergizes with iron chelator deferasirox (DSX) to inhibit the growth of
clinical isolates. A small number of
isolates were resistant to the combination, prompting us to search for other compounds that could synergize with TS against those strains.
