    Sammanfattning : Norovirus (NoV) is today recognized as the most important agent of acute human gastroenteritis, causing a high number of diarrheal episodes in both adults and children. Outbreaks in hospitals, nursing homes, day-care centers, and from consumption of contaminated food and drinking water are common. Wastewater can be a source of NoV dissemination, e. LÄS MER

  2. 2. The Norovirus Puzzle Characterization of human and bovine norovirus susceptibility patterns

    Sammanfattning : Winter vomiting disease is caused by norovirus (NoV) and affects millions of people every year resulting in 200.000 deaths among children in developing countries. It was observed early that not all individuals exposed to the norovirus became ill. The reason for this is now recognized to be dependent upon the secretor status of an individual. LÄS MER

  3. 3. On norovirus outbreaks and transmission in hospitals

    Detta är en avhandling från Lund University: Faculty of Medicine

    Författare :Carl-Johan Fraenkel; Lund University.; Lunds universitet.; [2019]

    Sammanfattning : Abstract Noroviruses are now the leading cause of gastroenteritis worldwide. Noroviruses are effectively transmitted due to a low infectious dose, viral shedding in high concentrations, environmental stability, and they induce only a limited immunity after infection. Especially, the norovirus variants of genotype II.4 (GII. LÄS MER

  4. 4. Norovirus Tracing in Environmental and Outbreak Settings - Experiences of waterborne, foodborne and nosocomial transmission

    Detta är en avhandling från Lund University: Faculty of Medicine

    Författare :Nancy P Nenonen; Göteborgs universitet.; Gothenburg University.; [2015]

    Sammanfattning : Noroviruses (NoV), a major cause of acute gastroenteritis in hospital settings, also occur as sporadic infections or periodic non-seasonal community outbreaks. Human NoV replicates to high concentration in the intestinal tract, is readily transmitted by the faecal-oral route, hand-to-hand contact, contaminated food and water, and by aerosols. LÄS MER

  5. 5. Norovirus, causative agent of winter vomiting disease, exploits several histo-blood group glycans for adhesion

    Detta är en avhandling från Lund University: Faculty of Medicine

    Författare :Gustaf E Rydell; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; norovirus; glycobiology; virus-like particle; FUT2; ABO H histo-blood group antigen; sialyl Lewis x; neoglycoprotein; glycosphingolipid; QCM-D; supported lipid bilayer;

    Sammanfattning : Norovirus is recognized as the major cause of outbreaks of gastroenteritis world-wide, yet no vaccines or drugs are available for prevention or treatment of the virus infection. Challenge studies and binding studies using virus-like particles (VLPs) have suggested susceptibility to norovirus infection to be associated with secretor status. LÄS MER
