چکیده

We cloned a gene, abeM, for a multidrug efflux pump from Acinetobacter baumannii using Escherichia coli as the host. Sequence analysis revealed that AbeM is a member of the MATE family of pumps. AbeM was found to be an H(+)-coupled multidrug efflux pump and a unique member of the MATE family.

Abstract Background: Efflux systems are components of the bacterial membrane that play a role in homeostasis of the cell and extrusion of toxic compounds. Efflux pumps of the resistance nodulation cell division (RND) superfamily, confer multidrug resistance to their host when over-expressed. One of the RND efflux systems, is AdeABC which have been characterized for A. baumannii. Another pump be...

Evaluation of Phenotypic and Genotypic Expression of Efflux Pumpin Clinical Isolates of Acinetobacter baumannii Resistant to Ciprofloxacin and Gentamicin

Introduction: Acinetobacter baumannii is an important bacteria because of high ability to obtain antibiotic resistance genes and creation of multi-drug resistant strains (MDR). Today, the active efflux pumps has been suggested as one of the most important mechanisms of intrinsic and acquired resistance of antibiotics in bacteria. The aim of this study was Evaluation of phenotypic and genotypic ...

Detection of Efflux Pump Using Ethidium Bromide-Agar Cartwheel Method in Acinetobacter baumannii Clinical Isolates

Introduction: In the past decade, multidrug-resistant Acinetobacter baumannii has become one of the most critical challenges in treating infected patients. The AdeABC efflux pump is the most important among the various resistance mechanisms. This pump can force various antibiotics and ethidium bromide out of the bacterial cell to the surrounding environment. Methods: In this study, nine A. baum...

Role of AbeS, a novel efflux pump of the SMR family of transporters, in resistance to antimicrobial agents in Acinetobacter baumannii.

In this study, a chromosomally encoded putative drug efflux pump of the SMR family, named AbeS, from a multidrug-resistant strain of Acinetobacter baumannii was characterized to elucidate its role in antimicrobial resistance. Expression of the cloned abeS gene in hypersensitive Escherichia coli host KAM32 resulted in decreased susceptibility to various classes of antimicrobial agents, detergent...
