Microbial biofilms may form on wide variety of surfaces and are problematic in medical, industrial environmental settings. Natural antibiofilm agents promising candidates for treatment biofilm-associated infections. One such natural products used therapeutic purposes is Alum (Sphatika). Besides, Ayurvedic Bhasmas various ailments India. In the present vitro study, anti-Biofilm potential as well...

Candida albicans is a commensal coloniser of the human gastrointestinal tract and an opportunistic pathogen, especially thanks to its capacity to form biofilms. This lifestyle is frequently involved in infections and increases the yeast resistance to antimicrobials and immune defenses. In this context, 38 lichen acetone extracts have been prepared and evaluated for their activity against C. alb...

Biofilm formation by human bacterial pathogens on implanted medical devices causes major morbidity and mortality among patients, and leads to billions of dollars in healthcare cost. Biofilm is a complex bacterial community that is highly resistant to antibiotics and human immunity. As a result, novel therapeutic solutions other than the conventional antibiotic therapies are in urgent need. In t...

We reported two forms (sphere and wire) of newly fabricated chlorhexidine (CHX)-loaded mesoporous silica nanoparticles (MSNs), and investigated their releasing capacities and anti-biofilm efficiencies. The interactions of the blank MSNs with planktonic oral microorganisms were assessed by field emission scanning electron microscopy. The anti-biofilm effects of the two forms of nanoparticle-enca...

Microbial biofilms have great negative impacts on the world's economy and pose serious problems to industry, public health and medicine. The interest in the development of new approaches for the prevention and treatment of bacterial adhesion and biofilm formation has increased. Since, bacterial pathogens living in biofilm induce persistent chronic infections due to the resistance to antibiotics...

Background and objectives: Quercus brantii subsp. persica is used in folk medicine to treat infections in Iran. There is not available report on the anti-biofilm activity of Quercus brantii subsp.  persica. The aim of the present study was to investigate the effects of Quercus brantii subsp. persica against...

objective(s): bacterial biofilm formation causes many persistent and chronic infections. the matrix protects biofilm bacteria from exposure to innate immune defenses and antibiotic treatments. the purpose of this study was to evaluate the biofilm formation of clinical isolates of pseudomonas aeruginosa and the activity of zinc oxide nanoparticles (zno nps) on biofilm. materials and methods: aft...

results the combination of bismuth ethanedithiol with ciprofloxacin showed synergistic inhibitory effect on the p. aeruginosa biofilm formation. the combination of bismuth ethanedithiol ciprofloxacin, ceftazidime and imipenem showed synergistic inhibitory effects on the biofilm formation. furthermore, the combination of bismuth ethanedithiol, imipenem and ceftazidime did not show any synergisti...

Objective(s):Serratia marcescens is one of the nosocomial pathogen. The ability to form biofilm is an important feature in the pathogenesis of S. marcescens. The aim of this study was to determine the anti-adhesive properties of a biosurfactant isolated from Lactobacillus acidophilus ATCC 4356, on S. marcescens strains. Materials and Methods: Lactobacillus acidophilus ATCC 4356, was selected a...

Screening of anti-biofilm compounds from the burdock leaf based on metabolomics is reported here. The crystal violet assay indicated 34% ethanol elution fraction of burdock leaf could completely inhibit biofilm formation of Pseudomonas aeruginosa at 1 mg·mL(-1). Then, the chemical composition of burdock leaf fraction was analyzed by ultra-performance liquid chromatography-mass spectrometry (UPL...
