adeabc 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 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 کاملResponse to Bile Salts in Clinical Strains of Acinetobacter baumannii Lacking the AdeABC Efflux Pump: Virulence Associated with Quorum Sensing
Introduction:Acinetobacter baumannii is an opportunistic nosocomial pathogen associated with multiple infections. This pathogen usually colonizes (first stage of microbial infection) host tissues that are in contact with the external environment. As one of the sites of entry in human hosts is the gastrointestinal tract, the pathogen must be capable of tolerating bile salts. However, studies ana...
متن کاملبررسی بیان و عملکرد ژن پمپ‌های افلاکس ایزوله‌های مقاوم به چند دارو در اسینتوباکتر بامانی غیرکلونال
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...
متن کاملTigecycline-based versus sulbactam-based treatment for pneumonia involving multidrug-resistant Acinetobacter calcoaceticus-Acinetobacter baumannii complex
BACKGROUND The treatment options for pneumonia involving multidrug-resistant Acinetobacter calcoaceticus-Acinetobacter baumannii (MDR Acb) complex are limited, and the optimal treatment has not been established. METHODS To compare the efficacy of tigecycline-based with sulbactam (or ampicillin/sulbactam)-based therapy for pneumonia involving MDR Acb complex, we conducted a retrospective study...
