Pseudomonas aeruginosa has been implicated as a foodborne and waterborne pathogen and is now considered a primary infectious agent. In the present study, the survival of P. aeruginosa inoculated in mineral water was evaluated by drop counts on Pseudomonas Agar Base (PAB), PAB with CN supplement X107, PAB with cetrimide, PAB with nalidixic acid, and these media with added FeSO(4). Initial counts...

Lipopolysaccharide (LPS) is the major surface component of gram-negative bacteria, and a component of LPS, lipid A, is recognized by the innate immune system through the Toll-like receptor 4/MD-2 complex. Pseudomonas aeruginosa, an environmental gram-negative bacterium that opportunistically infects the respiratory tracts of patients with cystic fibrosis (CF), can synthesize various structures ...

The respiratory tracts of bronchiectasis patients may be persistently colonized with Pseudomonas aeruginosa, despite intensive chemotherapy. The organism may undergo phenotypic changes in these patients, providing misleading typing results by conventional methods. We prospectively studied eight bronchiectasis patients without cystic fibrosis over a period of 1 year. A high microbial load of P. ...

Due to annually recurring mass gatherings in Makkah, Saudi Arabia could be a hot spot for the collection of multidrug-resistant strains such as Pseudomonas aeruginosa (P. aeruginosa). The various genotypes of extended spectrum beta-lactamases (ESBLs) are SHV, TEM, CTX-M types VEB, PER, BEL-1, BES-1, ESBL enzymes in P. aeruginosa. The present study aimed to identify the prevalence these genes in...

Pseudomonas aeruginosa strains exhibit significant variability in pathogenicity and ecological flexibility. Such interstrain differences reflect the dynamic nature of the P. aeruginosa genome, which is composed of a relatively invariable "core genome" and a highly variable "accessory genome." Here we review the major classes of genetic elements comprising the P. aeruginosa accessory genome and ...

conclusions the results of this study indicated that a decrease in oprd gene expression is an important mechanism of resistance in carbapenem resistant pseudomonas aeruginosa isolated from severe burn patients with secondary infection. results our study showed that 94.2% of the isolates were resistant to imipenem, 99.5% to meropenem, and all were resistant to ertapenem. the oprd gene expression...

PURPOSE This study was designed to determine whether the ability to adversely affect corneal epithelial cell health is a factor common to Pseudomonas aeruginosa keratitis strains and to assess the prevalence of each pathogenic phenotype and genotype in a canine model of naturally-acquired P. aeruginosa ocular infection. METHODS P. aeruginosa ocular isolates were collected by sampling 100 dogs...

UNLABELLED The aim of our study was to determine the prevalence of Pseudomonas aeruginosa bacteremia, risk factors, and outcome of patients treated at the Hospital of Kaunas University of Medicine. MATERIAL AND METHODS All hospitalized patients with blood culture positive for Pseudomonas aeruginosa during the 5-year period were included. A retrospective data analysis was performed to evaluate...

introduction: pseudomonas aeruginosa is one of the leading causes of nosocomial infections, and antibiotic resistance of this pathogen is an important concern in treating such infections. the current work was conducted to investigate the prevalence of bla-imp, and bla-vim metallo-beta-lactamase (mbl) among clinical and environmental p. aeruginosa isolates obtained from icus of different hospita...

conclusions according to our results, blatem-116 was the most frequent isolated esbl gene among the p. aeruginosa strains isolated from patients. results ciprofloxacin and piperacillin were the most efficient antipseudomonal agents. the results disclosed that 19 (16.37%) of the isolates were multidrug resistant and 8 (6.89%) were esbl-positive. of the 116 isolates, 30 (25.86%) were resistant to...
