evaluation of oprd gene expression in carbapenem-resistant pseudomonas aeruginosa strains isolated from severe burn patients with secondary infection
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...
متن کاملInsertional inactivation of oprD in carbapenem-resistant Pseudomonas aeruginosa strains isolated from burn patients in Tehran, Iran
In this study, we report the insertion sequence ISPpu21 in the oprD porin gene of carbapenem-resistant Pseudomonas aeruginosa isolates from burn patients in Tehran, Iran. Antibiotic susceptibility tests for P. aeruginosa isolates were determined. Production of metallo-β-lactamases (MBLs) and carbapenemase was evaluated and the β-lactamase-encoding and aminoglycoside-modifying enzyme genes were ...
متن کاملInvestigation of OprD Porin Protein Levels in Carbapenem-Resistant Pseudomonas aeruginosa Isolates.
BACKGROUND The Pseudomonas aeruginosa porin OprD is a substrate-specific porin that facilitates the diffusion of basic amino acids, small peptides, and carbapenems into the cell. OprD-mediated resistance occurs as a result of decreased transcriptional expression of oprD and/or loss of function mutations that disrupt protein activity. OBJECTIVES In this study, we examined the level of oprD exp...
متن کاملTransmissible strains of Pseudomonas aeruginosa in cystic fibrosis lung infections.
Pseudomonas aeruginosa chronic lung infections are the major cause of morbidity and mortality associated with cystic fibrosis. For many years, the consensus was that cystic fibrosis patients acquire P. aeruginosa from the environment, and hence harbour their own individual clones. However, in the past 15 yrs the emergence of transmissible strains, in some cases associated with greater morbidity...
متن کاملAntibiotic Susceptibility of Pseudomonas Aeruginosa Isolated from Cystic Fibrosis Patients
Abstract Background and Objective: Cystic fibrosis (CF) is an autosomal recessive genetic disease and Pseudomonas aeruginosa is one of the most common bacteria colonized in CF patients. Growing resistance of this bacterium to antibiotics now a day is a challenge of controlling infection in CF patient. In this study colonization of CF patients with Pseudomonas aeruginosa and antibiotic suscep...
