RND-type efflux pumps in multidrug-resistant clinical isolates of Acinetobacter baumannii: major role for AdeABC overexpression and AdeRS mutations.
Increased expression of chromosomal genes for resistance-nodulation-cell division (RND)-type efflux systems plays a major role in the multidrug resistance (MDR) of Acinetobacter baumannii. However, the relative contributions of the three most prevalent pumps, AdeABC, AdeFGH, and AdeIJK, have not been evaluated in clinical settings. We have screened 14 MDR clinical isolates shown to be distinct ...
متن کاملMultidrug resistant Acinetobacter baumannii--the role of AdeABC (RND family) efflux pump in resistance to antibiotics.
Acinetobacter baumannii is an opportunistic pathogen which play the more and more greater role in the pathogenicity of the human. It is often attached with the hospital environment, in which is able easily to survive for many days even in adverse conditions. Acinetobacter baumannii is the species responsible for a serious nosocomial infections, especially in the intensive care units. Option of ...
متن کاملadeabc efflux pump genes in multidrug resistant acinetobacter baumannii isolates
conclusions adeabc efflux system plays a vital role in multidrug resistance in clinical a. baumannii isolates. it was noted that the most important gene responsible for multidrug resistance within this system was the adeb gene especially in carbapenems resistance. methods this study was conducted on 84 multidrug resistant and 13 carbapenem-susceptible a. baumannii isolates obtained from burn an...
متن کاملRelative Gene Expression of RND-Type Efflux Pumps in Tigecycline Resistant Acinetobacter Baumannii Isolated from Training Hospitals in Tehran, Iran
Background: Appearance of multi-drug resistance (MDR) Acinetobacter baumannii imposes limitation on antibiotic therapy in patients. Detection of MDR A. baumannii can play a crucial role to prevent MDR strains spreading in hospitals. The aim of this study was determination the efflux pumps gene expression in tigecyclin resistance strains in collected isolates from selected training hospitals in ...

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...
