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

    Author : Nancy P Nenonen; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Norovirus; tracing; environment; foodborne; outbreak; waterborne; nosocomial; mussels; GI.1; oysters; GII.4; dust; surfaces; air; molecular epidemiology;

    Abstract : 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. READ MORE

  4. 2. Evolution of streamlined genomes in ultra-small aquatic bacteria

    Author : Weizhou Zhao; Siv Andersson; Sandra L. Baldauf; Sarahi L Garcia; Karen Lloyd; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; streamlined genome; aquatic bacteria; single cell genomics; metagenomics; evolutionary genomics; salinity; Baltic Sea; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : This thesis investigates the evolutionary processes of streamlined genomes from aquatic bacteria adapting to different salinities, using two groups of ultra-small aquatic bacteria (LD12 Alphaproteobacteria and acI Actinobacteria). Due to difficulties in obtaining pure cultures of these bacteria, culture-free approaches (single-cell genomics and metagenomics) were used to construct and compare genomes, and to study the mechanisms and selective forces of adaptation to freshwater, brackish, and marine ecosystems.

  5. 3. Lagovirus europaeus GI.2/RHDV2 (Rabbit Haemorrhagic Disease Virus 2) : expanding the paradigm of a pathogenic lagovirus

    Author : Aleksija Neimane; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Rabbit haemorrhagic disease (RHD) was first detected in 1984 and quickly spread among wild and domestic European rabbits (Oryctolagus cuniculus) throughout the world. RHD and European brown hare syndrome (EBHS), a related disease of hares (Lepus spp.), are caused by pathogenic lagoviruses of the Family Caliciviridae. READ MORE

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

    Author : Gustaf E Rydell; Göteborgs universitet; []
    Keywords : norovirus; glycobiology; virus-like particle; FUT2; ABO H histo-blood group antigen; sialyl Lewis x; neoglycoprotein; glycosphingolipid; QCM-D; supported lipid bilayer;

    Abstract : 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. READ MORE
