Phenotypic Investigation of Biofilm Formation and the Prevalence of icaA and icaD Genes in Staphylococcus epidermidis Isolates
Background and Aims: The most important factor for pathogenicity of Staphylococcus epidermidis is the ability to produce biofilm. Identification of biofilm-forming strains using an appropriate method and recognizing the mechanisms of biofilm formation can help understand the proper use of artificial medical equipment and prevent increased drugs resistance . The aim of this study was to 1) evalu...
متن کاملEffect of the nanoliposomal formulations of rifampin and N-acetyl cysteine on staphylococcus epidermidis biofilm
Objective(s): Staphylococcus epidermidis is a common cause of medical device-associated infections due to biofilm formation, and its elimination is extremely challenging. Although rifampin efficacy against S. epidermidis biofilms has been confirmed, its use as a single agent may lead to resistance. As such, it is assumed that the combination of rifampin and N-acetylcysteine (NAC) could exert ad...
متن کاملInhibition of Staphylococcus epidermidis biofilm formation by rabbit polyclonal antibodies against the SesC protein.
Several well-studied proteins with defined roles in Staphylococcus epidermidis biofilm formation are LPXTG motif-containing proteins. Here, we investigate the possible use of the LPXTG motif-containing protein SesC (S. epidermidis surface protein C; accession no. NP_765787) as a target for antibodies to prevent biofilm formation. In vitro and in a in vivo rat model of catheter infection, gene a...
متن کاملAlcoholic ingredients in skin disinfectants increase biofilm expression of Staphylococcus epidermidis.
The pathogenesis of Staphylococcus epidermidis is correlated with biofilm formation. We investigated the effect of three common alcoholic skin disinfectants, ethanol, n-propanol and isopropanol, on the biofilm formation of 37 clinical, icaADBC-positive S. epidermidis isolates. In alcohol-supplemented media 18 strains displayed increased biofilm expression. Sixteen of 19 strains were generally i...
متن کاملبررسی اثـر نانـوذرات نقـره بر بیـوفیلم‌های ناشی از استافیلوکوکوس اپیدرمیدیس
Background and Objective: Staphylococcus epidermidis produces extracellular polysaccharide which is known as a biofilm. Biofilm is highly effective in establishing of this bacterium infections and can be formed on medical devices that are used in the body. The purpose of this study was to evaluate the effects of silver colloidal nanoparticles on bacterial growth and biofilm form...
