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...

conclusions bacterial resistance against chlorhexidine is increasing. sub-mic doses of chlorhexidine digluconate can stimulate the formation of biofilm strains. materials and methods forty clinical isolates of escherichia coli, salmonella serotypes, staphylococcus. aureus and streptococcus agalactiae (10 isolates for each) were examined for chlorhexidine digluconate effects on biofilm formation...

The ability of uropathogenic E. coli (UPEC) to cause symptomatic UTI is associated with the expression of a variety of virulence factors. Biofilm formation enables UPEC to resist the flow of urine and increases its tolerance to antimicrobials and the host immune response. The measurement of biofilm formation in vitro is affected by the type of culture medium used. The aim of this study was to e...
