Biofilm formation by Staphylococcus aureus represents a problem in both the medical field and the food industry, because the biofilm structure provides protection to embedded cells and it strongly attaches to surfaces. This circumstance is leading to many research programs seeking new alternatives to control biofilm formation by this pathogen. In this study we show that a potent inhibition of b...

INTRODUCTION Biofilm production is considered a potential virulence factor of some Candida species. For this reason, an understanding of biofilm behavior of Candida albicans and its closely related species Candida dubliniensis is key to the development of effective preventive measures for invasive and oral candidiasis. The aim of this study was to compare the capacity of biofilm production by b...

Background and Objectives Staphylococcus epidermidis produces biofilm by extracellular polysaccharides, causing bacterial adherence to different surfaces. Anti-microbial effects of nickel nanoparticles on some bacterial strains such as S. aureus and Escherichia coli have been determined in limited studies. The aim of the present study is to examine the inhibitory effect of nickel nanoparticles ...

BACKGROUND Pseudomonas aeruginosa is an opportunistic pathogen that takes advantages of some weaknesses in the immune system to initiate an infection. Biofilms of P. aeruginosa can cause chronic opportunistic infections in immunocompromised and elderly patients. This bacterium is considered as a model organism to study antibiotic resistance as well as biofilm formation. In the biofilm structure...

AIM Polymethyl-methacrylate (PMMA) is commonly used primarily for baseplates of orthodontic appliances (BOA). The activities of cariogenic bacteria in biofilm on these surfaces may contribute to dental caries, gingival inflammation and periodontal disease. The PMMA incorporated with nanoparticles of silver (NanoAg-I-PMMA) and NanoAg in situ in PMMA (NanoAg-IS-PMMA) have been shown to control th...

background : verbascum thapsus (vt) is a medicinal plant that chemical constituents of it revealed the presence of biologically active compounds with antibacterial properties. the aim of the present study was to evaluate the antimicrobial and anti-adherent activities of ethanol extract of (vt) against of three oral streptococci in vitro. methods : in this study, biofilm formation of s. mutans 1...

AIMS The demonstration of the antibiofilm effects of pharmaceutical microemulsions. METHODS AND RESULTS Microemulsions were prepared as physically stable oil/water systems. Previous work by this group has shown that microemulsions are highly effective antimembrane agents that result in rapid losses of viability in planktonic populations of Pseudomonas aeruginosa and Staphylococcus aureus. In ...
