conclusions data reported here indicated that there is no specific genetic combination beyond the quantity of biofilm biomass in s. epidermidis. biofilm biomass seemed to be controlled by rnaiii expression level. further interest should be directed to biofilm dispersal since it seems that the key difference in biofilm biomass ability of s. epidermidis strains relates to factors regulating this ...

P. aeruginosa has been mentioned as the major causative agents of nosocomial infections. Pseudomonas infections are often serious and show different resistance to treatment due to distribution of antimicrobial resistance. Meanwhile, some strains are also able to form biofilm during contamination, which help bacteria to be even more persisyant to yreatment. We examined the antibiotic resistance ...

wound infections are a common cause of staphylococcal infections. an ability of s.aureus is to adhere and form biofilm on host surfaces. biofilm is an exopolysaccharide, a slime matrix around multiple layers of cells and is mediated by expression of the icaadbc operon. the present study evaluated the biofilm forming capacity and the presence of icaad gene among s.aureus isolated from wound infe...

abstract the role of fluorescent pseudomonads in biocontrol of take-all disease caused by gaeumannomyces graminis var.tritici (ggt) has been the subject of many researchs in the recent years. biofilm formation in fluorescent pseudomonads play an important role in biocontrol disease. for this purpose,130 strains of fluorescent pseudomonads isolated from wheat rhizosphere in different regions of ...

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. ...

OBJECTIVES To investigate the biofilm-forming related factors against MRSA bloodstream isolates and evaluates their clinical features and treatment outcomes by biofilm production. METHODS We collected 126 consecutive methicillin-resistant Staphylococcus aureus (MRSA) causing blood stream infections (BSIs) at 10 tertiary hospitals from 2007 to 2009. We investigated biofilm-forming ability usin...

Background: Some microorganisms can adhere to food handling surfaces forming biofilms that pose a safety challenge. This study was done to evaluate bacterial biofilm formation in milking equipments in Lilongwe, Malawi. Methods: Pooled milk (n=54) and water (n=60) samples were collected from households and milk bulking groups in Lilongwe, Malawi. Swabbing (n=46) and rinsing (n=16) were done on ...

introduction: biofilm forming staphylococcus epidermidis is a main causative agent of infections related to medical devices. purification and evaluation of gly-ta polysaccharide from a biofilm-forming s. epidermidis as a putative vaccine candidate were the main goals of the current study. methods: taking advantage of size exclusion chromatography procedure, glycerol teichoic acid (gly-ta) was p...

BACKGROUND Very few data exist on risk factors for developing biofilm-forming Candida bloodstream infection (CBSI) or on variables associated with the outcome of patients treated for this infection. METHODS AND FINDINGS We identified 207 patients with CBSI, from whom 84 biofilm-forming and 123 non biofilm-forming Candida isolates were recovered. A case-case-control study to identify risk fact...
