Evaluation of the effect of IDR-1018 antimicrobial peptide and chitosan nanoparticles on imipenem susceptible and resistant Pseudomonas aeruginosa isolated from patients with urinary tract infections from ICU
Background and aim: Excessive use of antibiotics has significantly increased resistance to common antibiotics in the treatment of urinary tract infections. In the present study, antimicrobial efficacy of chitosan nanoparticles and peptide IDR-1018 was evaluated against P. aeruginosa isolates. Methods: In the present study, 20 resistant and 20 sensitive P. aeruginosa isolates to imipenem were ...
متن کاملInvestigation of MexAB-OprM efflux pump gene expression in clinical isolates of pseudomonas aeruginosa isolated from Intensive Care Unit
Background and Aims: Pseudomonas aeruginosa is one of the most important pathogens of nosocomial infections, especially in the ICU (Intensive Care Unit), which has resistance to a wide range of antibiotics, especially Carbapenems. Among the most important resistance mechanisms of this bacteria against carbapenems are MexAB-OprM efflux pump. Therefore, the aim of this study was to evaluate the g...
متن کاملEffect of Mutation in Efflux Pump Regulatory Protein (MexR) of Pseudomonas aeruginosa: A Bioinformatic Study
ABSTRACT Background and Objectives: Pseudomonas aeruginosa is an important non-fermenting gram-negative hospital-acquired pathogen. Treatment of P. aeruginosa infections has become more challenging due to overexpression of efflux pumps. The aim of the present study was to apply in silico analysis to evaluate the structure of the effl...
متن کاملevaluation 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...
