یکی از تواناییهای باکتریهای فلورسنت سودومونادس ترشح متابولیتهایی از قبیل سیانید هیدروژن، پروتئاز، سالیسیلیکاسید و سیدروفور است که این مواد از رشد بیمارگرهای موجود در خاک جلوگیری میکنند. برای سنجش توانایی و میزان تولید این مواد توسط برخی استرینهای موجود (Pseudomonas fluorescens و نیز P. aeruginosa)، یکسری آزمونها انجام گرفت. در محیط کشت مربوط به هر آزمون، استرینهای P. aeruginosa 7NSK2، U...
Background and Objective: Burn wound infections caused by Pseudomonas aeruginosa exhibiting β-lactam antibiotic resistance are one of the greatest challenges of antimicrobial treatment. In this context, P. aeruginosa strains harboring resistance mechanisms, such as production of extended-spectrum beta-lactamases have the highest clinical impact no the management of burn wound infections. The ai...
Pseudomonas aeruginosa possesses a polar flagellum made up of flagellin subunits that encoded by fliC gene. Flagellin from several strains of P. aeruginosa on the basis of reaction with polyclonal antibodies and apparent molecular weight was divided into a or b types. Material and Methods: After extraction of the genomic DNA from two standard strains 8821M (Type a) and PAO1 (Type b) and some c...
Background: The resistance of Pseudomonas aeruginosa strains to broad spectrum cephalosporins may be mediated by extended spectrum b-lactamases (ESBLs). These enzymes are encoded by different genes located either on chromosome or plasmids. In this study, we determined the antimicrobial resistance patterns of P. aeruginosa isolates and screened for ESBL production. Methods: After isolation from...
background : due to the importance of the metal zinc as an essential biological element with known toxic properties, and considering the widespread secondary infections caused by pseudomonas aeruginosa strains with resistance to antibiotics and disinfectants, the present study aimed at exploring the antimicrobial properties of the metal zinc in both clinical and environmental multiple drug resi...
Pseudomonas aeruginosa is an opportunistic pathogen that causes chronic lung infections in cystic fibrosis (CF) patients. One characteristic of P. aeruginosa CF isolates is the overproduction of the exopolysaccharide alginate, controlled by AlgR. Transcriptional profiling analyses comparing mucoid P. aeruginosa strains to their isogenic algR deletion strains showed that the transcription of cya...
virulent and resistant strains pseudomonas aeruginosa ( p. aeruginosa) is one of the most important cause of utis in pediatrics. the present study was carried to investigate the frequency of virulence factors in the multi-drug resistant strains of p. aeruginosa isolated from pediatrics hospitalized due to the utis. one - hundred and forty three urine samples were collected from pediatric patie...
Pseudomonas aeruginosa is an opportunistic pathogen which is evolving resistance to many currently used antibiotics. While much research has been devoted to the roles of pathogenic P. aeruginosa in cystic fibrosis (CF) patients, less is known of its ecological properties. P. aeruginosa dominates the lungs during chronic infection in CF patients, yet its abundance in some environments is less th...
A comparison has been made of the sensitivities to various antibiotic and non-antibiotic substances of some strains of Pseudomonas aeruginosa and P. stutzeri, the latter including strains isolated from eye and other cosmetic products and from other sources. Whereas P. aeruginosa strains showed a high resistance to cetrimide and to benzalkonium chloride, the P. stutzeri strains were generally mo...
OBJECTIVES To assess the prevalence, levels of antimicrobial susceptibility and resistance mechanisms of Pseudomonas. METHODS A total of 445 clinical isolates and 200 environmental isolates were collected from three hospitals in Minia, Egypt. The MICs of different antibiotics were determined using the agar dilution method. The isolates were tested for beta-lactamase production and for the pre...
