Effect 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 کاملSpread of Efflux Pump Overexpressing-Mediated Fluoroquinolone Resistance and Multidrug Resistance in Pseudomonas aeruginosa by using an Efflux Pump Inhibitor
BACKGROUND Fluoroquinolone resistance in Pseudomonas aeruginosa may be due to efflux pump overexpression and/or target mutations. We designed this study to investigate the efflux pump mediated fluoroquinolone resistance and check the increasing effectiveness of fluoroquinolones in combination with an efflux pumps inhibitor among P. aeruginosa isolates from burn wounds infections. MATERIALS AN...
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 کاملMexXY-OprM efflux pump is necessary for a adaptive resistance of Pseudomonas aeruginosa to aminoglycosides.
Exposure of Pseudomonas aeruginosa to aminoglycosides frequently selects for recalcitrant subpopulations exhibiting an unstable, "adaptive" resistance to these antibiotics. In this study, we investigated the implication in the phenomenon of MexXY-OprM, an active efflux system known to export aminoglycosides in P. aeruginosa. Immunoblotting experiments demonstrated that the transporter MexY, but...
متن کاملDetermining a pattern for antibiotic resistance in clinical isolations of pseudomonas aeruginosa
Background: Pseudomonas aeruginosa is an opportunistic pathogen and one of the important factors of hospital infection. It causes many issues such as urinary tract infections, respiratory infection in cystic fibrosis patients, and wound infection in burn patients, septicemia and meningitis. Antibiotic resistance through various mechanisms is one of the challenges for the treatment of pseudomona...
