Abstract

Pseudomonas aeruginosa is an opportunistic human pathogenic bacterium that is a common cause of both acute and chronic infections. Multidrug-resistant P. aeruginosa poses a significant challenge to antibiotics and therapeutic approaches due to its pathogenicity, virulence, and biofilm-forming ability mediated by quorum sensing. Understanding the pathogenic mechanisms is essential for developing potential drug targets. In this regard, strategies aimed at combating the targeted inhibition of virulence, quorum sensing pathways, secretion systems, biofilm-associated two-component systems, and signalling system regulators (such as c-di-GMP) associated with biofilm formation are critical. Several new antimicrobial agents have been developed using these strategies, including antimicrobial peptides, bacteriophages, nanoantibiotics, photodynamics, and natural products, which are considered promising therapeutic tools. In this review, we address the concept of biofilms, their regulation, and recent treatment strategies to target P. aeruginosa, a clinically significant pathogen known for biofilm formation.
