Abstract Six biofilm carriers with different polymer were studied in fixed-film systems under anoxic conditions. Different media of polymers influence wastewater treatment performance. The aim this study was to investigate polymeric materials, polyethylene terephthalate (PET), polyvinyl chloride (PVC), polypropylene (PP), high-density (HDPE), and polymethyl methacrylate (acrylic), that affect b...

conclusions the remarkable rates of biofilm production ability among clinically isolated staphylococci emphasize the necessity of more effective infections control policies to prevent biofilm formation on medical devices and hospital environmental surfaces. background biofilm formation capacity is recognized as an important virulence factor in staphylococci that makes the organisms more resista...

objective(s):bacterial biofilm has been considered responsible for many deaths and high health costs worldwide. their better protection against antibacterial agents compared to free living cells leads to poor treatment efficiency. nanotechnology is promising approach to combat biofilm infections. the aim of the present study was to eradicate staphylococcus epidermidis biofilm with silver nanopa...

the aim of this study was to evaluate the ability of 15 serotypes of salmonella to form biofilm on polystyrene, polyvinyl chloride (pvc) and glass surfaces. .initially slime production was assessed on cra agar and hydrophobicity of 20 salmonella strains isolated from poultry and human and two salmonella enterica serovar typhimurium references strains was achieved by microbial adhesion to n-hexa...

Background: Microbial biofilms are responsible for many human infections and increase of antibiotic resistant bacteria. Therefore, finding an efficient way to prevent infection and biofilm formation of bacteria is essential. Medicinal plants are among suitable candidates to inhibit biofilm formation of bacteria. The aim of this study was to evaluate the antimicrobial effects of...

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...

Background: Staphylococcus hominis has been recently emerged as an opportunistic hospital-associated pathogen. The aim of this study was to characterize the antimicrobial susceptibility pattern, biofilm formation, and staphylococcal cassette chromosome mec (SCCmec) types among clinical isolates of S. hominis obtained from pediatric infections. Methods: Totall...

Background and Objective: Despite the critical importance of catheter as an indwelling medical device, its prolonged utilization in hospitalized patients may lead to infection. This study aimed to identify distribution of uropathogenic bacteria isolated from catheterized uro-oncology patients, their biofilm production, and antimicrobial resistance patterns to generally -used antibiotics. Mater...

Background & Aims of the Study: Rhodococci according to possess large genome, their active metabolism and survival under extreme conditions, are highly regarded for biodegradation and bioremediation of different pollutants especially heavy metals in the environment. Biofilms are more resistant to heavy metals than free-swimming organisms. The aim of this study was biofilm forma...
