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...

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

The versatile and ubiquitous Pseudomonas aeruginosa is an opportunistic pathogen causing acute and chronic infections in predisposed human subjects. Here we review recent progress in understanding P. aeruginosa population biology and virulence, its cyclic di-GMP-mediated switches of lifestyle, and its interaction with the mammalian host as well as the role of the type III and type VI secretion ...

the emergence of multi-drug resistant strains of pseudomonas aeruginosa has complicated treatment decision and may lead to treatment failures. in this study, we describe the trends of drug-resistant p. aeruginosa isolated in blood cultures from patients detected in a tertiary teaching hospital and evaluated the prevalence of resistance to amikacin, ampicillin, carbeni- cillin, cefixime, cefotax...
