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...

Biofilms cause significant problems in the environment and during the treatment of infections. However, the molecular mechanisms underlying biofilm formation are poorly understood. There is a particular lack of knowledge about biofilm maturation processes, such as biofilm structuring and detachment, which are deemed crucial for the maintenance of biofilm viability and the dissemination of cells...

background & objectives:  methicillin resistance staphylococcus aureus (mrsa) is one of the most important pathogens that causes several nosocomial and community infections. adhesion to surfaces and biofilm formation is considered main step in staphylococcal infection. the aims of this study were to determine presence oficaabcd genes and relation to the biofilm formation in of mrsa isolates...

Objective: Intravascular catheter-associated infection has been increasing hospitalization in post-surgery patients mainly due to microbial colonization of the catheter surface and formation of a superficial biofilm layer. The present study is aimed in developing an effective antibacterial device which can prevent colonization of organisms by modification of catheter. Methods: In the present st...

Background and objectives: Carbapenem-resistant and biofilm producing Enterobacteriaceaeare a major health problem. This study was carried to determine the antibacterial and antibiofilm activity of grape seed extract (GSE) against carbapenem-resistant and biofilm producing Enterobacteriaceae isolates. Methods: Antibiotics susceptibility pattern...

Background: The aim of this study was to compare the biofilm formation and the prevalence of biofilm-associated genes between the isolates of methicillin-resistant (MRSA) and methicillin-susceptible (MSSA) Staphylococcus aureus. Methods: In total, 209 S. aureus isolates were collected. The antibiotic susceptibility test was conducted using nine antibiotics according to the guidelines of Clinica...

conclusions minimum biofilm eradication values of ciprofloxacin obtained in the study are close to the values of the minimal inhibition concentration (mic). results all tested strains formed a biofilm. a value of 1.0 μg/ml ciprofloxacin is mbe50 for the strains of both tested species. an mbe90 value of ciprofloxacin for isolates of p. vulgaris was 2 μg/ml and for p. mirabilis was 512 μg/ml. mat...

Introduction: Biofilm formation in Staphylococcus aureus is a major virulence factor. Both methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA) are common causes of community- and hospital-acquired infections and are associated with biofilm formation. The status of biofilm-forming genes has not been explored in Jordanian nasal carriers of S. ...
