Role of autolysin-mediated DNA release in biofilm formation of Staphylococcus epidermidis

Plasma can reduce Staphylococcus epidermidis biofilm formation on medical polymers

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...

Cadmium Modulates Biofilm Formation by Staphylococcus epidermidis

The aim of the study was to evaluate the effect of cadmium exposure on Staphylococcus epidermidis (ATCC 35984) biofilm formation. Bacteria were cultured in the absence or presence of different concentrations (0-50 µM) of cadmium. Biofilm formation and bacterial viability were assessed. Quantitative Real Time-PCR (qRT-PCR) was used to determine the mRNA expression of molecular markers of S. epid...

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...

Staphylococcus epidermidis biofilm pdf

CcpA coordinates central metabolism and biofilm formation in Staphylococcus epidermidis.

Staphylococcus epidermidis is an opportunistic bacterium whose infections often involve the formation of a biofilm on implanted biomaterials. In S. epidermidis, the exopolysaccharide facilitating bacterial adherence in a biofilm is polysaccharide intercellular adhesin (PIA), whose synthesis requires the enzymes encoded within the intercellular adhesin operon (icaADBC). In vitro, the formation o...
