Background: The increasing emergence of antimicrobial resistance among gram negative bacteria especially Enterobacteriaceae has become a global problem. Klebsiella pneumoniae is an opportunistic pathogen, which recently due to causing broad spectrum of disease and antibiotic resistance has been lionized. Efflux pumps are one of the antibiotic resistance mechanisms, which were introduced in t...

Background & Aims: Today, increasing resistance to antibiotics causes serious problems for treatment of patients. The aim of this study was to determine the role of AdeABC efflux pump in the Benzalkonium chloride and Chlorhexidine MIC value with efflux pump inhibitors (1-1-naphthylmethyl-piperazine and phenyl-arginine-β-naphthylamide) in the A.baumanii strains isolated from intensive care ...

Background: This study aimed to evaluate the role of efflux pump regulator and OXA-23 genes in imipenem resistance Acinetobacter baumannii strains isolated from hospitalized patients in Tehran, Iran. Methods: This study was conducted on 60 A. baumannii isolates collected from pa...

staphylococcus aureus causes a wide variety of infections worldwide. methicillin-resistant s. aureus is one of most common causes of nosocomial and community acquired infections. the fluoroquinolones are an important class of antibiotics that used to treat infections caused by s. aureus. today, a significant increase in the rate of ciprofloxacin resistance in methicillin-resistant s. aureus str...

The NorA efflux pump considered as one of the contributors to antibiotic resistance in Staphylococcus aureus strains. One of the challenges of the researchers is finding natural plant compounds with the ability to inhibit the pumps. The aim of this study was to investigate the inhibitory effect of thyme (Thymus vulgaris) extract on NorA efflux pump in ciprofloxacin-resistant strains of S. aureu...

Background and Objective: Antibiotic resistant phenotypes of bacteria have been shown to be related to efflux pumps. Research for finding compounds with an ability to inhibit these pumps seems worthwhile due to their ability to increase bacterial sensitivity to antibiotics or return sensitivity to resistant strains. The aim of this study was to evaluate inhibitory effect of Thymus daenensis ess...

OBJECTIVES This study was conducted to examine the role of the CmeABC efflux pump in decreasing the susceptibility of Campylobacter coli to macrolides and ketolides in the context of absence or presence of mutations in the 23S rRNA genes. METHODS The cmeB gene was inactivated in strains of C. coli showing two different patterns of erythromycin resistance (low or high level of resistance) asso...

Background and Aim: Ciprofloxacin-resistant Salmonella spp. are among the most important causative agents of food-borne infections. The marA efflux pump in this bacterium plays a significant role in the development of drug resistance. The aim of this study was to investigate marA efflux pump gene expression in Ciprofloxacin resistant Salmonella enteritidis clinical strains by Real Time PCR. Mat...

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...
