Healthcare-associated infections pose a significant global health challenge, negatively impacting patient outcomes and burdening healthcare systems. A major contributing factor to healthcare-associated is the formation of biofilms, structured microbial communities encased in self-produced extracellular polymeric substance matrix. Biofilms are critical disease etiology antibiotic resistance, complicating treatment infection control efforts. Their inherent resistance mechanisms enable them withstand therapies, leading recurrent increased morbidity. This review explores development biofilms their dual roles disease. It highlights structural protective functions EPS matrix, which shields populations from immune responses antimicrobial agents. Key molecular biofilm including restricted penetration, persister cell dormancy, genetic adaptations, identified as barriers effective management. implicated various clinical contexts, chronic wounds, medical device-associated infections, oral complications, surgical site infections. prevalence hospital environments exacerbates challenges underscores urgent need for innovative preventive therapeutic strategies. evaluates cutting-edge approaches such DNase-mediated disruption, RNAIII-inhibiting peptides, DNABII proteins, bacteriophage nanoparticle-based solutions, coatings, lock therapies. also examines associated with biofilm-related diagnostic difficulties, disinfectant economic implications. emphasizes multidisciplinary approach importance understanding dynamics, role pathogenesis, advancements strategies combat biofilm-associated effectively settings. These insights aim enhance reduce burden diseases.

Proteus mirabilis has been identified as the third most frequent reason for catheter-associated urinary tract infections. The production of urease significantly enhances force catheter blockage caused by biofilm formation. Because biofilms are important virulence factors that make antibiotics less potent, it is becoming increasingly to develop novel alternative antibiotics. In addition unique properties they possess, nanoparticles made from metal oxide currently attracting considerable attention possible antibacterials. This research aims explore potential anti-biofilm green manufactured ZnO-CuO generated P. mirabilis. By synthesizing reductive enzymes, bacterial cells can participate in biosynthesis process. study explores whether synthesized work an agent formed These were using Bacteriocins determine their effectiveness against bacteria, which partially purified and showed antimicrobial activity Gram-negative bacteria AFM, TEM, FESEM, XRD, ultraviolet (UV)–visible spectroscopy used analyze biosynthesized ascertain chemical physical characteristics.

Preclinical models of osseointegrated orthopaedic implants tend to focus on implant stability, surface modifications enhance integration with host tissue, and reduction in iatrogenic contamination through antibiotic-eluting/bacteria-resistant coatings. While these studies are imperative early success osseointegration, continued percutaneous devices throughout the lifespan patient is also critically important. A perpetual challenge formation bacterial biofilm abutment. Once adhered, biofilm-based bacteria recalcitrant readily contaminate subcutaneous soft tissue stoma. To this end, rabbit model reported herein replicates clinical scenario a biofilm-contaminated This enables preclinical testing advanced therapeutics beyond traditional antibiotic-based approach, potentially increasing longevity device.
