Phage-first treatment results in subpopulation-driven collateral sensitivity to beta-lactams in an extensively drug-resistant Pseudomonas aeruginosa
ABSTRACT Nosocomial Pseudomonas aeruginosa infections are among the most challenging infections to treat, and resistance to last-line agents, including polymyxins and aztreonam-based therapies, risks a future with limited or no clinical treatment options. Bacteriophages (phages) have emerged as a promising therapeutic...
