A comparison of extended spectrum β-lactamase producing Escherichia coli from clinical, recreational water and wastewater samples associated in time and location
Jørgensen, Silje; Søraas, Arne Vasli; Arnesen, Lotte S; Arnesen, Lotte Pia Stenfors; Leegaard, Truls Michael; Sundsfjord, Arnfinn; Jenum, Pål (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-17)Extended spectrum β-lactamase producing Escherichia coli (ESBL-EC) are excreted via effluents and sewage into the environment where they can re-contaminate humans and animals. The aim of this observational study was to detect and quantify ESBL-EC in recreational water and wastewater, and perform a genetic and phenotypic comparative analysis of the environmental strains with geographically associated ... -
Fecal carriage of extended spectrum β-lactamase producing Escherichia coli and Klebsiella pneumoniae after urinary tract infection - A three year prospective cohort study
Jørgensen, Silje; Søraas, Arne Vasli; Sundsfjord, Arnfinn; Liestøl, Knut; Leegaard, Truls Michael; Jenum, Pål (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-07)We have performed a prospective cohort study to investigate the duration of and risk factors for prolonged fecal carriage of ESBL-producing Escherichia coli or Klebsiella pneumoniae in patients with community acquired urinary tract infection caused by these bacteria. From 2009 to 2011, 101 Norwegian patients were recruited. Stool swabs and questionnaires were collected every three months for one ... -

Dyrhovden, Ruben; Eagan, Tomas Mikal Lind; Fløtten, Øystein; Siljan, William Ward; Leegaard, Truls Michael; Bø, Bjørnar; Fardal, Hilde; Grøvan, Fredrik; Kildahl-Andersen, Arne; Larssen, Kjersti Wik; Tilseth, Rune; Hjetland, Reidar; Løes, Sigbjørn Suk; Lindemark, Frode; Tellevik, Marit Gjerde; Breistein, Rebecca Irene; Kommedal, Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-22)Background - Many community-acquired pleural infections are caused by facultative and anaerobic bacteria from the human oral microbiota. The epidemiology, clinical characteristics, pathogenesis, and etiology of such infections are little studied. The aim of the present prospective multicenter cohort study was to provide a thorough microbiological and clinical characterization of such oral-type pleural ...
