pseudomonas aeruginosa as an opportunistic pathogen is a significant cause of acute and chronic infections in patients with compromised defenses. this bacterium is motile via a single polar flagellum made of polymerized flagellin subunits differentiated into two major serotypes: a and b. flagellin plays an important role as a virulence factor in the adhesion, colonization and invasion of p. aer...

objective: pseudomonas aeruginosa is the major cause of septicemia and wound infection in burned patients. immunotraphy is the best practical way for prevention and treatment of these infections. flagella as one of the most important bacterial virulence factors has important role in attachment, motility, chemotaxis and tlr-5-dependent immune response so that it propounded as a vaccine candidate...

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, meropenem, g...

background and objectives: pseudomonas aeruginosa is a gram-negative, aerobic bacterium found in water and soil. it is a normal flora in skin and gastrointestinal tract of human beings. p. aeruginosa as an opportunistic pathogen involved in nosocomial infections having multiple pathogenic factors and shows high rate of resistance to different antibiotics. the aim of this study was to identify t...

background & objectives: pseudomonas aeruginosais one of the most important causes of nosocomial infections particularly in immunodeficient patients. several antibiotics such as betalactams, aminoglycosides and quinolones are used for the treatment of infections caused by this organism, but the prevalence of multidrug resistant strains has been reported frequently. beta lactamase production is ...

in the present study, four carbon sources were tested for the polyester synthesis of pseudomonas aeruginosa pa01 which is a ubiquitous environmental bacterium and is one of the top three causes of opportunistic human infections. these included linear c8 to c11 carboxylic acids. octanoic acid, nonanoic acid, decanoic acid and undecanoic acid were added to m1 minimal medium to final concentration...

Pseudomonas aeruginosa is an opportunistic pathogen that causes a variety of infections in compromised patients. The ability of Pseudomonas aeruginosa to produce chronic infection is based in part on its ability to biosynthesis of biofilm, and alginate is the major polysaccharide in the synthesized biofilm. So alginate degradation is very essential in the dispersion of Pseudomonas aeruginosa bi...

A simple method of detection of FP plasmids with chromosome-mobilizing ability in Pseudomonas aeruginosa has been developed.
