Background & Aims: Microorganisms are protected from antimicrobial agents when placed in biofilm structure. Biofilm-producing microorganisms are responsible for many problems in industry and medicine; therefore, it is essential to find new techniques for removing and inhibiting biofilms. This study aimed to examine the antimicrobial effect of Eucalyptus camaldulensis alcoholic extracts against ...

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...

BACKGROUND To study chlorhexidine digluconate disinfectant effects on planktonic growth and biofilm formation in some bacterial field isolates from animals. OBJECTIVES The current study investigated chlorhexidine digluconate effects on planktonic growth and biofilm formation in some field isolates of veterinary bacterial pathogens. MATERIALS AND METHODS Forty clinical isolates of Escherichi...

Background: Pseudomonas aeruginosa biofilm is one of the problems in antibiotic treatment of infections. Nanomedicines such as chitosan can carry multiple drugs and improve the therapeutic effects of antibiotics. Objectives: The study aimed to synthesis and characterization of ciprofloxacin loaded chitosan nanoparticle for eradication biofilm of P. aeroginosa. Methods: Cipro-CS microparticles...

conclusions finally, it can be suggested that the extracts of this plant be applied as antimicrobial agents against these pathogens, particularly in biofilm forms. results the results showed that the a. sativum l. extract discs did not have any zone of inhibition for the tested bacteria. however, the mic values of a. sativum l. extracts (0.078 - 2.5 mg/ml) confirmed the high ability of these ex...

background and objectives: pseudomonas aeruginosais an important opportunistic pathogen. the mucoid strains of p. aeruginosa produce hyper viscous substances consisting mainly of alginate which have important roles in formation of biofilm.we investigated the effect of essential oil of matricaria chamomilla l. on biofilm production in p. aeruginosa. material and methods: p. aeruginosa 8821m was ...

background : incidence of  white  spots due  to  demineralization of  enamel  and  gingival problems  is  an  unacceptable  result  of  orthodontic  treatment.  plaque  accumulation  and bacterial biofilm growth are responsible for these phenomena. the resin-based dental composites used as bonding agents in orthodontics play a major role in mentioned problems. as recent researches assert the an...

Medical polymers, such as urinary catheters are widely used biomaterials. One of the main problem for using the urinary catheters is biofilm formation on their surface, when they are used in a long time in the body. Virulence and pathogenicity of Staphylococcus epidermidis is often enhanced when growing as a biofilm. Many techniques have been presented to reduce the biofilm formation by surface...

BACKGROUND Microbial cells growing in biofilms, play a huge role in the spread of antimicrobial resistance. In this study, biofilm formation of Klebsiella strains belonging to 3 different Klebsiella species (K. ornithinolytica, K. oxytoca and K. terrigena), cooccurences' effect on biofilm formation amount and anti-biofilm effects of Citrus limon and Zingiber officinale essential oils on biofilm...
