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...

background and objectives : over the last two decades, both the incidence of nosocomial candidaemia and the proportion of blood stream infection due to candida spp. other than candida albicans have increased. the aims of this study was to identify different species of candida and risk factors associated with bloodstream infection and detection of biofilm production. materials and methods : this...

Bacterial biofilm is a major factor in delayed wound healing and high levels of biofilm production have been repeatedly described in multidrug resistant organisms (MDROs). Nevertheless, a quantitative correlation between biofilm production and the profile of antimicrobial drug resistance in delayed wound healing remains to be determined. Microbial identification, antibiotic susceptibility and b...

INTRODUCTION Because of increasing difficulty in treating enterococcal infections, effort is being devoted to understanding factors that are responsible for causing nosocomial infection, with a focus toward targeting these factors with new therapeutics. Evidence has emerged that the esp gene mediates biofilm formation in vitro, which helps the organism colonize and cause infection. METHODOLOG...

  Background : Pseudomonas aeruginosa is one of important opportunistic pathogen, that cases serious infections . It produces many virulence factors, and this bacterium usually is resistance against antimicrobial agents.   Objective :The aim of this study was evaluate the effects of sub-MICs of essential oils of Mentha spicata and Cumminum cyminum on alginate production, biofilm formation, swim...

Background & Objective: Staphylococcus aureus, especially methicillin-resistant S. aureus (MRSA), represent serious nosocomial and community infections. Biofilm formation as an important virulence factor may be affected by sub-inhibitory levels of antibiotics. Few studies examined the effects of all therapeutic antimicrobial agents on...

background and objectives: pseudomonas aeruginosais an important opportunistic pathogen. the mucoid strains of p. aeruginosa produce hyper viscous substances consisting mainly of alginate which have important roles in formation of biofilm.we investigated the effect of essential oil of matricaria chamomilla l. on biofilm production in p. aeruginosa. material and methods: p. aeruginosa 8821m was ...

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...

Biofilm production in bacteria causing infections is of recent interest especially in relation to emerging drug resistance and increased use of medical devices. The present study was performed to determine biofilm production among pathogenic Gram positive cocci in association with antibiotic resistance and other risk factors. A total of 100 clinical isolates of Staphylococcus aureus (50) and en...

Urinary tract infection (UTI) is the most commonly acquired bacterial infection. Antibiotic resistance of uropathogens has been known to increase worldwide and biofilm production being the prime cause. The objective of this study was to detect the production of biofilm by uropathogens isolated from UTIs and their antimicrobial susceptibility pattern. A total 570 urine samples from clinically su...
