First report of OXA-143-lactamase producing Acinetobacter baumannii inQom
Objective(s):Antibiotic resistance in Acinetobacter baumannii and outbreaks caused by this organism have been reported from several areas of the world. The present study aimed at determining the antibiotic susceptibility profiles and the distribution of OXA-type beta-lactamases among Iranian Acinetobacter baumannii isolates from Qom of Iran. Materials and Methods: For this study, 108 non-duplic...
متن کاملMolecular epidemiology, antimicrobial susceptibility and carbapenemase resistance determinants among Acinetobacter baumannii clinical isolates in Taiwan.
BACKGROUND Emerging carbapenem resistance among Acinetobacter baumannii clinical isolates is a worldwide problem. Infections caused by A. baumannii are increasing and demonstrate high mortality rates. This study aimed to establish a nationwide surveillance of antimicrobial susceptibility, carbapenemase genes, and clonal relationships of A. baumannii clinical isolates in Taiwan. METHODS Clinic...
متن کاملPolyclonal spread of bla(OXA-23) and bla(OXA-58) in Acinetobacter baumannii isolates from Argentina.
BACKGROUND In order to study the enzymatic carbapenem resistance mechanisms in Acinetobacter baumannii isolates from Argentina, we performed molecular characterization on 41 epidemiologically unrelated strains isolated from 1995 to 2006 with diminished susceptibilities to imipenem and meropenem. METHODOLOGY Acinetobacter baumannii isolates were identified with the ARDRA technique. The total g...
متن کاملبررسی ژنهای اگزاسیلیناز در ایزولههای بالینی اسینتوباکتربامانی مقاوم به کرباپنم در بیمارستان شهید محمدی بندرعباس درسال 1393
Background and Objective: Acinetobacter baumannii is considered as an important agent in nosocomial infections. The problem facing the tratment of these bacteria is increasing resistance to antimicrobial agents such as carbapenems. The main mechanism of resistance to carbapenems in these bacteria is the presence of oxacillinases genes, which belong to class D betalactamases. The aim of this st...
متن کاملIsolation and genetic characterization of metallo-β-lactamase and carbapenamase producing strains of Acinetobacter baumannii from patients at Tehran hospitals
BACKGROUND AND OBJECTIVE Carbapenems are therapeutic choice against infections caused by gram-negative bacilli including strains of Acinetobacter baumannii. Resistance to these antibiotics is mediated by efflux pumps, porins, PBPs and ß-lactamases. The aim of this study was to determine the possibility of existence of MBLs, OXAs and GES-1 betalactamase genes among clinical isolates of Acinetoba...
