    • Elevated Plasma Levels of P‐Selectin Glycoprotein Ligand‐1 Positive Microvesicles in Patients with Unprovoked Venous Thromboembolism 

      Jamaly, Simin; Basavaraj, Manjunath Goolyam; Starikova, Irina; Olsen, Randi; Brækkan, Sigrid K.; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-31)
      Background<br> Microvesicles (MVs) express antigens from their parental cells and have a highly procoagulant surface. Animal studies suggest that P‐Selectin Glycoprotein Ligand‐1 positive (PSGL‐1+) MVs play a role in the pathogenesis of venous thromboembolism (VTE).<p> Objective<br> The aim of this study was to determine plasma levels, the cellular origin and the morphological characteristics ...

    • Fitness costs of various mobile genetic elements in Enterococcus faecium and Enterococcus faecalis 

      Starikova, Irina; Al-Haroni, Mohammed; Werner, Guido; Roberts, Adam P.; Nielsen, Kåre M.; Johnsen, Pål Jarle (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-07-05)
      Objectives: To determine the fitness effects of various mobile genetic elements (MGEs) in Enterococcus faecium and Enterococcus faecalis when newly acquired. We also tested the hypothesis that the biological cost of vancomycin resistance plasmids could be mitigated during continuous growth in the laboratory.<p> <p>Methods: Different MGEs, including two conjugative transposons (CTns) of the Tn916 ...

    • A Trade-off between the Fitness Cost of Functional Integrases and Long-term stability of Integrons 

      Starikova, Irina; Harms, Klaus; Haugen, Pål; Lunde, Tracy Munthali; Primicerio, Raul; Samuelsen, Ørjan; Nielsen, Kaare Magne; Johnsen, Pål Jarle (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Horizontal gene transfer (HGT) plays a major role in bacterial microevolution as evident from the rapid emergence and spread of antimicrobial drug resistance. Few studies have however addressed the population dynamics of newly imported genetic elements after HGT. Here, we show that newly acquired class-1 integrons from Salmonella enterica serovar Typhimurium and Acinetobacter baumannii, free of ...
