Effects of Sub-Minimum Inhibitory Concentrations of Silver Nanoparticles on Some Virulence Factors of Staphylococcus aureus
ABSTRACT Background and Objectives: Silver nanoparticles (AgNPs) have physical and surface properties that could threaten human and environmental health. AgNPs are classified as ‘very toxic’ to eukaryotic organisms and are less toxic to bacteria. The aim of the present study was to study the effects of different sub-minimum inhi...
متن کاملEffect of sub-minimum inhibitory concentrations of ciprofloxacin, amikacin and colistin on biofilm formation and virulence factors of Escherichia coli planktonic and biofilm forms isolated from human urine
The aim of this study was to determine the effect of subinhibitory concentrations (sub-MICs) of ciprofloxacin, amikacin and colistin on biofilm formation, motility, curli fimbriae formation by planktonic and biofilm cells of E. coli strains isolated from the urine of patients with various urinary system infections. Quantification of biofilm formation was carried out using a microtiter plate ass...
متن کاملEffects of Sub-inhibitory Concentrations of Essential Oils of Mentha spicata and Cumminum cyminum on Virulence Factors of Pseudomonas aeruginosa
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...
متن کاملThe association of biofilm formation and sub-minimal inhibitory concentrations of antimicrobial agents
Introduction: Although bacteria producing biofilm are more resistance to antimicrobial agents, biofilm formation can stimulated by sub-minimal inhibitory concentrations (sub-MICs) of some antimicrobial agents. Therefore, we designed present study to investigate the in vitro efficacy of several antibiotics (including ceftazidime, piperacillin, ticarcillin, carbenicillin, aztreonam, merop...
