The fight to keep resistance at bay, epidemiology of carbapenemase producing organisms (CPOs), vancomycin resistant enterococci (VRE) and methicillin resistant Staphylococcus aureus (MRSA) in Norway, 2006-2017
Elstrøm, Petter; Astrup, Elisabeth; Hegstad, Kristin; Samuelsen, Ørjan; Enger, Hege; Kacelnik, Oliver (Peer reviewed; Journal article, 2019)Introduction: Scandinavian countries have traditionally had a low prevalence of resistant organisms, but have in recent years experienced a change in their epidemiology. We aim to describe the epidemiology of carbapenema ... -
Novel genomic islands and a new vanD-subtype in the first sporadic VanD-type vancomycin resistant enterococci in Norway
Al-Rubaye, Mushtaq; Janice, Jessin; Bjørnholt, Jørgen Vildershøj; Jakovljev, Aleksandra; Hultström, Maria Elisabeth; Sundsfjord, Arnfinn; Hegstad, Kristin (Peer reviewed; Journal article, 2021)Background - Vancomycin-resistant enterococci (VRE) represent several types of transferable vancomycin resistance gene clusters. The vanD type, associated with moderate to high level vancomycin resistance, has only ... -
Silenced vanA gene cluster on a transferable plasmid cause outbreak of vancomycin variable enterococci
Sivertsen, Audun; Pedersen, Torunn Annie; Larssen, Kjersti Wik; Bergh, Kåre; Rønning, Torunn Gresdal; Radtke, Andreas; Hegstad, Kristin (Journal article; Peer reviewed, 2016-05)We report an outbreak of vancomycin-variable vanA+ enterococci (VVE) able to escape phenotypic detection by current guidelines and demonstrate the molecular mechanisms for in vivo switching into vancomycin resistance and ...
