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...

objective(s): pseudomonas aeruginosa is a nosocomial pathogen resistant to most antimicrobial treatments. furthermore, it persists in adverse environments thereby forming biofilms on various surfaces. researchers have therefore focused on antibiofilm strategies using nanoparticles due to their unique physicochemical properties. superparamagnetic iron oxide nanoparticles (sionps) have recently s...

Differential gene expression in biofilm cells suggests that adding the derepressed conjugative plasmid R1drd19 increases biofilm formation by affecting genes related to envelope stress (rseA and cpxAR), biofilm formation (bssR and cstA), energy production (glpDFK), acid resistance (gadABCEX and hdeABD), and cell motility (csgBEFG, yehCD, yadC, and yfcV); genes encoding outer membrane proteins (...

Nowadays silver nanoparticles (AgNPs) are used as antimicrobial due to its well known physical, chemical, and biological properties. A large collection of bacterial cells adhering to a surface is called bacterial biofilm. Exposure to silver nano particles (AgNPs) may prevent colonization of new bacteria onto the biofilm. In the present work, we have investigated whether the biofilm format...

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 ...
