Antibiotic sensitivity screening of Klebsiella spp. and Raoultella spp. isolated from marine bivalve molluscs reveal presence of CTX-M-producing K. pneumoniae
Håkonsholm, Fredrik; Hetland, Marit A.K.; Svanevik, Cecilie Smith; Sundsfjord, Arnfinn; Lunestad, Bjørn Tore; Marathe, Nachiket (Journal article; Peer reviewed, 2020-11)Klebsiella spp. are a major cause of both nosocomial and community acquired infections, with K. pneumoniae being responsible for most human infections. Although Klebsiella spp. are present in a variety of environments, ... -
Gastrointestinal carriage of Klebsiella pneumoniae in a general adult population: a cross-sectional study of risk factors and bacterial genomic diversity
Raffelsberger, Niclas Peter; Hetland, Marit Andrea Klokkhammer; Svendsen, Kristian; Småbrekke, Lars; Löhr, Iren Høyland; Andreassen, Lotte; Brisse, Sylvain; Holt, Kathryn E.; Sundsfjord, Arnfinn; Samuelsen, Ørjan; Gravningen, Kirsten Midttun (Journal article; Peer reviewed, 2021)Antibiotic resistant Klebsiella pneumoniae is a leading public health threat and gastrointestinal carriage is an established risk factor for subsequent infections during hospitalization. Our study contributes new knowledge ... -
A nationwide genomic study of clinical Klebsiella pneumoniae in Norway 2001–15: introduction and spread of ESBLs facilitated by clonal groups CG15 and CG307
