Review Highlights Diverse Strategies for Biofilm Disruption in Recurrent Urinary Tract Infections

Biofilm formation is a critical microbial survival mechanism, enabling bacterial persistence and recurrence in urinary tract infections (UTIs), particularly in patients with catheters or structural abnormalities. These complex microbial communities significantly reduce antibiotic efficacy and drive the development of antibiotic resistance. Current standard-of-care often struggles against biofilm-associated infections, leading to high recurrence rates. This review addresses the urgent need for novel approaches by exploring diverse strategies that directly target biofilm structures and communication pathways.

This comprehensive review synthesizes recent advancements in microbiology and materials science, focusing on diverse therapeutic approaches to combat biofilm formation in recurrent urinary tract infections (UTIs). The authors systematically examine current and investigational strategies, categorizing them by their primary mechanism of action against bacterial persistence and antibiotic resistance. The review covers a broad spectrum of modalities, from molecular interventions like quorum sensing inhibition to material-based solutions such as nanoparticle systems, providing a landscape of emerging therapeutic options.

The review identifies several key emerging strategies for biofilm disruption. These include the inhibition of quorum-sensing mechanisms, which are crucial for bacterial communication and biofilm maturation. Another significant category involves the enzymatic or chemical degradation of extracellular polymeric substances (EPS), the protective matrix of biofilms, thereby exposing bacteria to antibiotics. > Antimicrobial peptides (AMPs) are highlighted for their ability to directly kill bacteria and disrupt biofilm structures, often with broad-spectrum activity. Furthermore, nanoparticle-based systems are discussed for their potential to deliver antimicrobials directly into biofilms or to possess intrinsic anti-biofilm properties. Finally, strategies involving microbiota modulation are explored as a means to restore a healthy microbial balance and prevent biofilm formation.
