    Background: Culicoides hypersensitivity (CH) is induced in horses by salivary allergens of Culicoides midges. In Iceland, the causal Culicoides species for CH are not present. Previous epidemiological data indicated that Icelandic horses are more ...
  • Doherty, T. Mark; Hausdorff, William P.; Kristinsson, Karl Gustaf (Informa UK Limited, 2020-06-29)
    Background: Antimicrobial resistance is a growing global health threat. To preserve the effectiveness of antimicrobials, it is important to reduce demand for antimicrobials. Objectives: The objective of the study was to screen the existing peer-reviewed ...
  • Benediktsson, Bardi; Bjornsson, Ragnar (American Chemical Society (ACS), 2020-08-05)
    The nitrogenase enzymes are responsible for all biological nitrogen reduction. How this is accomplished at the atomic level, however, has still not been established. The molybdenum-dependent nitrogenase has been extensively studied and is the most ...
