Adherence of mucoid and nonmucoid strains of Pseudomonas aeruginosa to tracheal epithelium was studied with a perfused-trachea model. The species specificity of adherence was studied by infecting tracheas from hamsters, guinea pigs, or mice. Perfused tracheas from hamsters were infected with strains of P. aeruginosa in the presence of various sugars, lectins, cations, or charged polymers. Adher...

background and objectives : carbapenem resistant pseudomonas aeruginosa is a serious cause of nosocomial infections.the main purpose of the study is to determine the prevalence rate of imipenem resistant pseudomonas aeruginosa carrying metallo- beta- lactamase (mbl) genes. material and methods : 236 pseudomonas aeruginosa isolates were collected from teaching hospitals of ahvaz university of me...

Introduction: Pseudomonas aeruginosa is a serious challenge for antimicrobial therapy, due to chromosomal mutations or intrinsic resistance to various antimicrobial agents, such as Metallo-β-Lactams (MBL). This study aimed to investigate the prevalence of β-lactamases encoding genes among P. aeruginosa strains isolated from intensive care unit (ICU) patients by phenotypic and multiplex PCR meth...

A total of 62 Pseudomonas aeruginosa strains isolated from two hospitals in Siedlce (Poland) were studied by repetitive element based PCR (rep-PCR) using BOX primer. BOX-PCR results revealed the presence of 7 numerous genotypes and 31 unique patterns among isolates. Generally, the strains of P. aeruginosa were characterized by resistance to many antibiotics tested and by differences in serogrou...

Staphylococcus aureus and Pseudomonas aeruginosa are common nosocomial pathogens responsible for biofilm-associated infections. Proton pump inhibitors (PPI), such as esomeprazole, may have novel antimicrobial properties. The objective of this study was to assess whether esomeprazole prevents sessile bacterial growth and biofilm formation and whether it may have synergistic killing effects with ...

Pseudomonas aeruginosa and Candida albicans are disparate microbial species, but both are known to be opportunistic pathogens frequently associated with nosocomial infections. The aim of this study was to provide a better understanding of the interactions between these microorganisms in dual-species biofilms. Several bacteriophage-resistant P. aeruginosa phenotypes have been isolated and were u...

Prior to modern typing methods, cross-infection of P. aeruginosa between people with cystic fibrosis (CF) was felt to be rare. Recently a number of studies have demonstrated the presence of clonal strains of P. aeruginosa infecting people with CF. The aim of this study was to determine whether strains of P. aeruginosa demonstrated differences in resistance to desiccation and whether preincubati...

BACKGROUND The ability of bacteria to develop common mechanisms of resistance to antibiotics and disinfectants raises doubts about the effectiveness of disinfection processes. Glucoprotamin (GP) is an antimicrobial active substance which is widely used to the disinfection in medical area. OBJECTIVE The aim of study was to compare GP's effectiveness with susceptibility of reference strains use...

pseudomonas aeruginosa is an important life-threatening nosocomial pathogen and plays a prominent role in serious infections in burned patients. the current study was undertaken to characterize p. aeruginosa strains isolated from burned patients in tehran, iran. the study was conducted in a major burn center in tehran, iran in 2007. a total of seventy specimens obtained from different clinical ...

background and objectives: cystic fibrosis (cf) is an autosomal recessive genetic disease.  infections in these patients gene.are  mostly  caused  by  three  bacteria:  staphylococcus  aureus ,  haemophilus  influenza and  particularly  pseudomonas aeruginosa .  carbapenems including antibiotics are used to combat infections with pseudomonas aeruginosa . in recent years, carbapenems resistant s...
