Targeting biofilm and virulence in Pseudomonas aeruginosa: AidH@SPEEK as a novel quorum-sensing inhibitor [PDF]

open access: yesMicrobiology Spectrum
Pseudomonas aeruginosa (PA), a gram-negative opportunistic pathogen, poses severe risks to immunocompromised patients. Conventional antibiotics often fail due to toxicity and resistance, primarily linked to biofilm formation controlled by quorum sensing (
