Characterization of a hospital outbreak of imipenem-resistant Acinetobacter baumannii by phenotypic and genotypic typing methods

Phenotypic and Genotypic Typing of Multidrug - resistant Acinetobacter Baumannii by Plasmid Profiles and Multiplex - PCR Typing

Profiles and Multiplex -PCR Typing,” Science Journal of Microbiology, Volume 2012, Article ID SJMB-274, 7 Pages, 2012. doi:10.7237/sjmb/274 Abstract–Acinetobacter baumannii, as important opportunistic pathogens, have been found to be responsible for an increasing number of Multiple-drug resistant(MDR) nosocomial infections in worldwide. In the present study, various isolates of MDR, obtained fr...

Comparison of outbreak and nonoutbreak Acinetobacter baumannii strains by genotypic and phenotypic methods.

Thirty-one Acinetobacter baumannii strains, comprising 14 strains from 14 outbreaks in different northwestern European cities and 17 sporadic strains, were compared by investigating various properties of the strains including biotype, antibiogram, cell envelope protein electrophoretic profile, ribotype pattern, and the band pattern generated by a novel genomic fingerprinting method, named AFLP,...

Phenotypic and genotypic characteristics of tetracycline resistant Acinetobacter baumannii isolates from nosocomial infections at Tehran hospitals

Objective(s):To date, the most important genes responsible for tetracycline resistance among Acinetobacter baumannii isolates have been identified as tet A and tet B. This study was carried out to determine the rate of resistance to tetracycline and related antibiotics, and mechanisms of resistance.  Materials and Methods: During the years 2010 and 2011, a total of 100 A. baumannii isolates we...

Phenotypic and Genotypic Detection of Metallo-Beta-Lactamases in Carbapenem Resistant Acinetobacter baumannii

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 ...
