Antimicrobial susceptibility testing of Bacteroides species by disk diffusion: The NordicAST Bacteroides study
Stubhaug, Tore Taksdal; Giske, Christian G.; Justesen, Ulrik S; Kahlmeter, Gunnar; Matuschek, Erika; Sundsfjord, Arnfinn; Skaare, Dagfinn (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-28)Objectives - Antimicrobial susceptibility testing (AST) of anaerobic bacteria has until recently been done by MIC methods. We have carried out a multi-centre evaluation of the newly validated EUCAST disk diffusion method for AST of Bacteroides spp.<p> <p>Methods - A panel of 30 Bacteroides strains was assembled based on reference agar dilution MICs, resistance gene detection and quantification ... -

Staphylococcus aureus bloodstream infections: Diverging trends of meticillin-resistant and meticillin-susceptible isolates, EU/EEA, 2005 to 2018
Gagliotti, Carlo; Högberg, Liselotte Diaz; Billström, Hanna; Eckmanns, Tim; Giske, Christian G.; Heuer, Ole E.; Jarlier, Vincent; Kahlmeter, Gunnar; Wong, Danilo Lo Fo; Monen, Jos; Murchan, Stephen; Simonsen, Gunnar Skov; Šubelj, Maja; Andrašević, Arjana Tambić; Żabicka, Dorota; Žemličková, Helena; Monnet, Dominique L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-18)Background: Invasive infections caused by Staphylococcus aureus have high clinical and epidemiological relevance. It is therefore important to monitor the S. aureus trends using suitable methods. Aim: The study aimed to describe the trends of bloodstream infections (BSI) caused by meticillin-resistant S. aureus (MRSA) and meticillin-susceptible S. aureus (MSSA) in the European Union (EU) and the ... -
Strong correlation between the rates of intrinsically antibiotic-resistant species and the rates of acquired resistance in Gram-negative species causing bacteraemia, EU/EEA, 2016
Jarlier, Vincent; Högberg, Liselotte Diaz; Heuer, Ole E.; Campos, Josó; Eckmanns, Tim; Giske, Christian G.; Grundmann, Hajo; Johnson, Alan P.; Kahlmeter, Gunnar; Monen, Jos; Pantosti, Annalisa; Rossolini, Gian Maria; van de Sande-Bruinsma, Nienke; Vatopoulos, Alkiviadis; Żabicka, Dorota; Žemličková, Helena; Monnet, Dominique L.; Simonsen, Gunnar Skov (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-15)<i>Background</i> - Antibiotic resistance, either intrinsic or acquired, is a major obstacle for treating bacterial infections.<p><p> <i>Aim</i> - Our objective was to compare the country-specific species distribution of the four Gram-negative species <i>Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa</i> and <i>Acinetobacter</i> species and the proportions of selected acquired ...
