Hospital-acquired infections, also known as nosocomial include bloodstream surgical site skin and soft tissue respiratory tract urinary infections. According to reports, Gram-positive Gram-negative pathogenic bacteria account for up 70% of infections in intensive care unit (ICU) patients. Biofilm production is a main virulence mechanism distinguishing feature bacterial pathogens. Most pathogens develop biofilms at the solid-liquid air-liquid interfaces. An essential requirement biofilm presence conditioning film. A film provides first surface on which can adhere fosters growth by creating favorable environment.

Biofilm formation is a serious problem that relatively often causes complications in orthopedic surgery. Biofilm-forming pathogens invade implanted foreign bodies and surrounding tissues. Such condition, if not limited at the appropriate time, requires reoperation. This can be partially prevented by selecting an prosthesis material prevents development of biofilm. There are many modern techniques available to detect formed By applying them we identify visualize biofilm-forming microorganisms. The most common etiological factors associated with biofilms orthopedics are: Staphylococcus aureus, coagulase-negative Staphylococci (CoNS), Enterococcus spp., whereas Gram-negative bacilli Candida spp. also deserve attention. It seems crucial, for therapeutic success, eradicate microorganisms able form biofilm after implantation endoprostheses. Planning effective targeted antimicrobial treatment postoperative infections accurate identification microorganism responsible procedure. microbiological testing described this article show diagnostic options followed enable implementation treatment.

Implant-associated infections are a frequent complication of surgeries involving biomaterial implants. Staphylococcus and Enterococcus species the leading causes linked to bone-anchored joint To address this challenge, developing antibacterial coatings prevent bacterial attachment biofilm formation on biomaterials is critical. This study aimed evaluate antibiofilm properties two coatings: titanium nitride (TiN) with silver nanoparticles (TiN/Ag). Antibacterial activity was tested against common biofilm-forming pathogens, including Escherichia coli, aureus, faecalis, faecium. The results demonstrated that both significantly reduced cell counts, TiN/Ag coating showing superior performance due addition nanoparticles. enhancement particularly effective in reducing across all strains, most pronounced effects observed for E. faecium faecalis. synergistically improved TiN coating, efficiently disrupting integrity adhesion. By surfaces, offer promising strategy minimize complications associated These findings highlight potential medical applications.

The current antibacterial strategies focus on antibiotic therapy and extensive hygienic measures during orthopedic surgery. However, potential development of implant-associated infections remains a persistent clinical challenge. There is, therefore, growing interest in introducing innovative safe for preventing combating biofilm implants. Antibacterial coatings, particularly, are attractive local delivery agents. We aim this proof-of-concept study at novel translatable implant coating approach, focusing directed assembly inverse non-lamellar lyotropic liquid crystalline (LLC) nanostructures implants prevention initial bacterial attachment formation through the widely used cationic colistin (COL). On exposure dry lipid films deposited model to aqueous solutions COL prepared different concentrations, set LLC coatings based commercial distilled monoglyceride product (or glycerol monooleate) were produced. In addition small-angle X-ray scattering (SAXS) characterization investigations, vitro studies conducted evaluating antibiofilm properties against Gram-negative bacteria Pseudomonas aeruginosa. SAXS analysis indicated that all samples bicontinuous cubic Pn3m phases.
