      Introduction: Coagulase-negative staphylococci (CoNS) are the most prevalent pathogens in nosocomial infections and may serve as a reservoir of mobile genetic elements such as the staphylococcal cassette chromosome mec (SCCmec) encoding methicillin resistance. Molecular characterization of SCCmec types combined with advanced molecular typing techniques may provide essential information for ...
    • Comparative Genomic Analysis of Staphylococcus haemolyticus Reveals Key to Hospital Adaptation and Pathogenicity 

      Pain, Maria Charlene Ronessen; Hjerde, Erik; Klingenberg, Claus; Cavanagh, Jorunn Pauline (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-10)
      <i>Staphylococcus haemolyticus</i> is a skin commensal gaining increased attention as an emerging pathogen of nosocomial infections. However, knowledge about the transition from a commensal to an invasive lifestyle remains sparse and there is a paucity of studies comparing pathogenicity traits between commensal and clinical isolates. In this study, we used a pan-genomic approach to identify factors ...

    • Culture-negative early-onset neonatal sepsis - at the crossroad between efficient sepsis care and antimicrobial stewardship 

      Klingenberg, Claus; Kornelisse, Rene F.; Buonocore, Giuseppe; Maier, Rolf F.; Stocker, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-09)
      Sepsis is a leading cause of mortality and morbidity in neonates. Presenting clinical symptoms are unspecific. Sensitivity and positive predictive value of biomarkers at onset of symptoms are suboptimal. Clinical suspicion therefore frequently leads to empirical antibiotic therapy in uninfected infants. The incidence of culture confirmed early-onset sepsis is rather low, around 0.4–0.8/1000 term ...

    • Efficacy of Intravenous, Endotracheal, or Nasal Adrenaline Administration During Resuscitation of Near-Term Asphyxiated Lambs 

      Songstad, Nils Thomas; Klingenberg, Claus; McGillick, Erin V.; Polglase, Graeme R.; Zahra, Valerie; Schmölzer, Georg M.; Davis, Peter G.; Hooper, Stuart B.; Crossley, Kelly J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-02)
      <i>Objectives</i>: Neonatal resuscitation guidelines recommend administering intravenous (IV) adrenaline if bradycardia persists despite adequate ventilation and chest compressions (CC). Rapid IV access is challenging, but little evidence exists for other routes of administration. We compared IV, endotracheal (ET), and intranasal routes for adrenaline administration during resuscitation of asphyxiated ...

    • Expired CO2 Levels Indicate Degree of Lung Aeration at Birth 

      Hooper, Stuart B.; Fouras, Andreas; Siew, Melissa; Wallace, Megan; Kitchen, Marcus; te Pas, Arjan B; Klingenberg, Claus; Lewis, Robert; Davis, Peter; Morley, Colin J.; Schmölzer, Georg M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      As neonatal resuscitation critically depends upon lung aeration at birth, knowledge of the progression of this process is required to guide ongoing care. We investigated whether expired CO2 (ECO2) levels indicate the degree of lung aeration immediately after birth in two animal models and in preterm infants. Lambs were delivered by caesarean section and ventilated from birth. In lambs, ECO2 levels ...
