Transition of blaOXA-58-like to blaOXA-23-like in Acinetobacter baumannii Clinical Isolates in Southern China: An 8-Year Study

Transition of blaOXA-58-like to blaOXA-23-like in Acinetobacter baumannii Clinical Isolates in Southern China: An 8-Year Study

BACKGROUND The prevalence of carbapenem-resistant Acinetobacter baumannii in hospitals has been increasing worldwide. This study aims to investigate the carbapenemase genes and the clonal relatedness among A. baumannii clinical isolates in a Chinese hospital. METHODS Carbapenemase genes and the upstream locations of insertion sequences were detected by polymerase chain reaction (PCR), and the...

Drug-resistant gene of blaOXA-23, blaOXA-24, blaOXA-51 and blaOXA-58 in Acinetobacter baumannii.

We distinguished the four alleles of OXA subgroups from 339 strains of Acinetobacter baumannii using Polymerase Chain Reaction, and investigated distributions of OXA subgroups in clinical isolated strains. A total of 196 Acinetobacter baumannii were isolated from the Central Hospital of Zhumadian between 2010 and 2014. Amplification of OXA genes, blaOXA-23, blaOXA-24, blaOXA-51 and blaOXA-58, w...

Two Multiplex Real-Time PCR Assays to Detect and Differentiate Acinetobacter baumannii and Non- baumannii Acinetobacter spp. Carrying blaNDM, blaOXA-23-Like, blaOXA-40-Like, blaOXA-51-Like, and blaOXA-58-Like Genes

Nosocomial infections caused by Acinetobacter spp. resistant to carbapenems are increasingly reported worldwide. Carbapenem-resistant Acinetobacter (CRA) is becoming a serious concern with increasing patient morbidity, mortality, and lengths of hospital stay. Therefore, the rapid detection of CRA is essential for epidemiological surveillance. Polymerase chain reaction (PCR) has been extensively...

First occurrence of blaOXA-58 in Acinetobacter baumannii isolated from a clinical sample in Southern Brazil

This is the first report of an Acinetobacter baumannii from clinical origin carrying the bla OXA-58 gene in Brazil. The isolate included in this study was from a patient during an outbreak in Porto Alegre, RS, Southern Brazil, in 2007. It was resistant to most of the beta-lactams tested, it has also the bla OXA-65 gene and the ISAbal sequence located upstream to both bla OXA genes detected and ...

Codetection of blaOXA-23-like gene (blaOXA-133) and blaOXA-58 in Acinetobacter radioresistens: report from the SENTRY antimicrobial surveillance program.
