Norwegian patients and retail chicken meat share cephalosporin-resistant Escherichia coli and IncK/bla resistance plasmids
Berg E, Wester A, Ahrenfeldt J, Mo S, Slettemeas J, Steinbakk M, et al.
Clin Microbiol Infect . 2017 Jan; 23(6):407.e9-407.e15. PMID: 28082191
Objectives: In 2012 and 2014 the Norwegian monitoring programme for antimicrobial resistance in the veterinary and food production sectors (NORM-VET) showed that 124 of a total of 406 samples (31%)...

The role of whole genome sequencing in antimicrobial susceptibility testing of bacteria: report from the EUCAST Subcommittee
Ellington M, Ekelund O, Aarestrup F, Canton R, Doumith M, Giske C, et al.
Clin Microbiol Infect . 2016 Nov; 23(1):2-22. PMID: 27890457
Whole genome sequencing (WGS) offers the potential to predict antimicrobial susceptibility from a single assay. The European Committee on Antimicrobial Susceptibility Testing established a subcommittee to review the current development...

Large IncHI2-plasmids encode extended-spectrum β-lactamases (ESBLs) in Enterobacter spp. bloodstream isolates, and support ESBL-transfer to Escherichia coli
Nilsen E, Haldorsen B, Sundsfjord A, Simonsen G, Ingebretsen A, Naseer U, et al.
Clin Microbiol Infect . 2013 Jun; 19(11):E516-8. PMID: 23800169
We investigated the prevalence of extended-spectrum β-lactamases (ESBLs) in Enterobacter spp. bloodstream isolates from 19 hospital laboratories in Norway during 2011. A total of 62/230 (27%) isolates were resistant to...

Rapid evolution and spread of carbapenemases among Enterobacteriaceae in Europe
Canton R, Akova M, Carmeli Y, Giske C, Glupczynski Y, Gniadkowski M, et al.
Clin Microbiol Infect . 2012 Apr; 18(5):413-31. PMID: 22507109
Plasmid-acquired carbapenemases in Enterobacteriaceae, which were first discovered in Europe in the 1990s, are now increasingly being identified at an alarming rate. Although their hydrolysis spectrum may vary, they hydrolyse...

Molecular characterization of VIM-producing Klebsiella pneumoniae from Scandinavia reveals genetic relatedness with international clonal complexes encoding transferable multidrug resistance
Samuelsen O, Toleman M, Hasseltvedt V, Fuursted K, Leegaard T, Walsh T, et al.
Clin Microbiol Infect . 2011 May; 17(12):1811-6. PMID: 21595797
VIM-producing Klebsiella pneumoniae (VPKP) has been identified as a source of hospital outbreaks and is prevalent particularly in the Mediterranean region. In this study we have characterized eight VPKP isolates...

Comparison of disk diffusion, Etest and VITEK2 for detection of carbapenemase-producing Klebsiella pneumoniae with the EUCAST and CLSI breakpoint systems
Vading M, Samuelsen O, Haldorsen B, Sundsfjord A, Giske C
Clin Microbiol Infect . 2010 Jul; 17(5):668-74. PMID: 20649801
The aim of this study was to compare CLSI and EUCAST MIC and disk diffusion carbapenem breakpoints for the detection of carbapenemase-producing Klebsiella pneumoniae. K. pneumoniae strains with known KPC...

A sensitive and specific phenotypic assay for detection of metallo-β-lactamases and KPC in Klebsiella pneumoniae with the use of meropenem disks supplemented with aminophenylboronic acid, dipicolinic acid and cloxacillin
Giske C, Gezelius L, Samuelsen O, Warner M, Sundsfjord A, Woodford N
Clin Microbiol Infect . 2010 Jul; 17(4):552-6. PMID: 20597925
Enterobacteriaceae producing carbapenemases, such as KPC or metallo-β-lactamases (MBLs), have emerged on several continents. Phenotypic tests are urgently needed for their rapid and accurate detection. A novel carbapenemase detection test,...
