Correlation of Ciprofloxacin Resistance with the AdeABC Efflux System in Acinetobacter baumannii Clinical Isolates
BACKGROUND Acinetobacter baumannii is one of the most important pathogens capable of colonization in burn patients, leading to drug-resistant wound infections. This study evaluated the distribution of the AdeABC efflux system genes and their relationship to ciprofloxacin resistance in A. baumannii isolates collected from burn patients. METHODS A total of 68 A. baumannii clinical strains were ...
متن کاملRND-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 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 کاملEvaluation 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 ...
متن کاملAssociation between mutations in gyrA and parC genes of Acinetobacter baumannii clinical isolates and ciprofloxacin resistance
Objective(s): We investigated the contribution of gyrA and parC mutational mechanism in decreased ciprofloxacin susceptibility of Acinetobacter baumannii isolated from burn wound infections. Materials and Methods: Ciprofloxacin susceptibility of 50 A. baumannii isolates was evaluated by disk diffusion and agar dilution methods. PCR and sequencing were performed for detection of mutation in gyr...
