Biofilm technology has been applied to polluted water treatment. The functional characteristics of biofilm play key roles in the decontamination efficiency and are affected by physicochemical properties carrier surface. Previous studies reported that larger specific surface area artificial carrier, more biofilms there attached its However, coupling relationship between metabolic activity remain...

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. ...

Biofilm, the aggregates of microbial layers that are attached on surface biofilter carriers, plays a central role in removal and conversion nutrients recirculating aquaculture systems (RAS). The bacterial activity biofilm involves autotrophic heterotrophic processes. These biological processes crucial for water quality RAS but difficult to monitor. In this study, we demonstrate new method based...

background methicillin -resistant staphylococcus aureus (mrsa) is associated with serious infections. having the ability of biofilm-formation decrease their susceptibility to antibiotics. objectives the aim of this study was to determine the prevalence of biofilm formation among mrsa isolated from nasal carriers in the beheshti teaching hospital in kashan, iran. materials and methods a cross-se...

Biofilm sloughing is an integral aspect, and a dynamic activity of biofilm development. This study focused on biofilm sloughing on carriers in integrated fixed-film activated sludge (IFAS) systems in both laboratory (LS; synthetic feed) and full-scale (FS; municipal) systems. During biofilm development in the LS system the relative hydrophobicity of flocs and biofilm increased with an increase ...

Histophilus somni is an opportunistic pathogen causing respiratory, genitourinary and generalized infections in cattle. An important virulence factor is its ability to produce a biofilm. The aim of this work was to confirm that H. somni Hsp60 (Gro-EL) is a constituent of the biofilm produced by this bacterium in vitro and to check whether or not the presence of a specific antibody within the cu...

Biofilm formation by nontypeable (NT) Haemophilus influenzae remains a controversial topic. Nevertheless, biofilm-like structures have been observed in the middle-ear mucosa of experimental chinchilla models of otitis media (OM). To date, there have been no studies of biofilm formation in large collections of clinical isolates. This study aimed to investigate the initial adhesion to a solid sur...
