The global spread of class A-carbapenemase-producing Enterobacteriaceae has made the development of a simple test a desirable goal. A disc diffusion test using imipenem was 100% sensitive and 96% specific in identifying carbapenemase-producing organisms, potentially reducing or eliminating the need for the relatively labor-intensive modified Hodge test.

the emergence of multidrug resistance (mdr) and extensively drug resistance (xdr) in acinetobacter baumannii has made an important challenge in the treatment of infections caused by this organism. the ability of carbapenemase production is one of the main mechanisms for the emergence of mdr and/or xdr in a. baumannii. the aim of this study was to detect carbapenemase producer a. baumannii. in t...

We evaluated the performance characteristics of chromID CARBA and HardyCHROM Carbapenemase for the detection of carbapenemase-producing Enterobacteriaceae (CPE). A CPE prevalence study was conducted using chromID CARBA; this demonstrated that in low-prevalence settings, CPE screening agars may lack specificity, and confirmation of putative isolates is necessary.

We report here the first identification of the worldwide spread of Klebsiella pneumoniae carbapenemase-2-producing and carbapenem-resistant K. pneumoniae clone ST258 in Turkey, a country where the distantly-related carbapenemase OXA-48 is known to be endemic. Worryingly, this isolate was also resistant to colistin, now considered to be the last-resort antibiotic for carbapenem-resistant isolates.

The emergence of multiple-carbapenemase-producing Acinetobacter strains has been a serious concern during the past decade. Here, we report the draft genome sequence of an Acinetobacter baumannii strain isolated from a Japanese patient with three acquired carbapenemase genes: blaNDM-1, blaTMB-1, and blaOXA-58.

PURPOSE Since November 2006, imipenem-resistant Acinetobacter baumannii isolates have increased in Kyung Hee University Hospital in Seoul, Korea. The purpose of this study was to determine the genetic basis and molecular epidemiology of outbreak isolates. MATERIALS AND METHODS Forty-nine non-repetitive isolates of the 734 IRAB strains were investigated in order to determine their characterist...

This study evaluated the performance of the Rapidec Carba NP test, which was introduced recently into the market for the detection of carbapenemase production in a broad spectrum of β-lactamase-producing Enterobacteriaceae clinical isolates. In total, 252 clinical Enterobacteriaceae isolates that had been genetically characterized with respect to carbapenemase, extended-spectrum β-lactamase (ES...

BACKGROUND Continue rise in unprofessional use of antibiotics in our hospitals and communities is worrisome. A research study was therefore conducted to detect extended spectrum beta-lactamase (ESBL), carbapenemase, metallobeta lactamase and their co-production phenotypically from isolates obtained from patients admitted to or attending two tertiary hospitals in Kano, Nigeria. METHOD A total ...

The recent emergence of carbapenemase-producing Enterobacteriaceae strains represents a major threat for hospitalized patients. We document the dissemination and control of carbapenemase-producing Klebsiella pneumoniae clones in a Greek hospital. During a 3-year study period (January 2009 to December 2011), carbapenemase-producing K. pneumoniae strains were isolated from clinical samples from 7...

1 integron showed 100% nucleotide sequence identity to the corresponding segment of a plasmid from the human clinical P. aeruginosa strain B3 isolated in Guangzhou (accession no. EU588392). Moreover, the 3 ′ conserved region of the integron (qacED1 and sul1) and the upstream region of the bla IMP-45 gene including aacA4, the 5 ′ conserved segment (intI1) of the integron and a Tn1403-like transp...
