BACKGROUND AND OBJECTIVES Staphylococcus aureus is an important pathogen and a frequent cause of infections associated with biofilm production in implantable medical devices. Biofilm production can be induced by sub-inhibitory concentrations (sub-MICs) of certain antibiotics, but few studies have researched this occurrence in S. aureus. In this study, we investigated the effect of sub-MICs of r...

conclusions: these data demonstrated that the attachment of bacteria to hydrophilic acrylic iols was more than hydrophobic pmma ones independent of the brand. according to these results the bacterial strain might have more hydrophilic properties. augmenting the biomass of biofilm by passing of time demonstrated the key role of time in biofilm formation on the iol surfaces. the differences betwe...

Purpose: Biofilm formation impairs wound healing and also protects the organisms from the action of antibiotics thereby associated with various hospital acquired infections. Currently S.epidermidis has been increasingly recognised as an important nosocomial pathogen due to its capability in forming biofilm. Hence this study is aimed to screen the incidence of biofilm producing clinical and skin...

Antibiotic-sensitive bacteria have been found to coexist with antibiotic-producing bacteria in biofilms, but little is known about how the former develop in such an environment. Here we isolated pyocyanin-sensitive bacteria belonging to the genus Brevibacillus from a biofilm derived from soil extract and based on the preestablished biofilm of a pyocyanin producer, Pseudomonas aeruginosa strain ...

background and aims: staphylococcus aureus is one of the important pathogens around the world. the present investigation was carried out to study the distribution of staphylococcal cassette chromosome mec (sccmec) types and antibiotic resistance properties in methicillin-resistant staphylococcus aureus isolated from isfahan hospitals. materials and methods: a total of 250 clinical specimens wer...

Objective(s): Acinetobacter baumannii has a high propensity to form biofilm and frequently causes medical device-related infections with multiple-drug-resistance in hospitals. The aim of this work is to study antimicrobial resistance and the role of bap and cpaA genes in biofilm formation by A. baumannii to understand how this pathogen persists in the hospital environment. Materials and Methods...

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...
