  1. 1. Conservation ecology of the thick-shelled river mussel Unio crassus : The importance of parasite-host interactions

    Författare :Lea Dominique Schneider; E. Martin Österling; P. Anders Nilsson; Johan Höjesjö; Caryn Vaughn; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Endangered species; freshwater mussels; host fish species; parasite-host; river; stream; Unio crassus; Unionoida; Biology; Biologi;

    Sammanfattning : Unionoid mussels are globally threatened and their conservation requires species-specific knowledge on their ecology and parasite-host interaction. Unio crassus is one of Europe’s most threatened unionoid species and has a temporary obligate parasitic life stage (glochidia) on fish. LÄS MER

  2. 2. Evolutionary and mechanistic aspects of insect host plant preference

    Författare :Alexander Schäpers; Niklas Janz; Steven Heard; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; host plant choice; host range; diet breadth; butterfly; oviposition; specialist; generalist; insect-plant interaction; search behavior; olfaction; decision making; evolution; parasite-host interaction; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Plant feeding insects comprise about 25% of all animal species on earth and play an important role in all ecosystems. Although we understand that their association with plants is a key-factor driving the diversification in this group, we still have large gaps in our knowledge of the underlying processes of this relationship.

  3. 3. Characterisation of surface traits of Helicobacter pylori and their role in the infectious process

    Författare :Christoffer Petersson; Roland Möllby; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The surface appendages of bacteria determine the initial contact with host cells. Characterisation of functional organisation and spatial distribution of adhesive traits of outer membrane components of Gram-negative bacteria is a key issue in studies of the parasite-host cell interaction.

  4. 4. Studies of Giardia-host interactions: role of cysteine-rich surface proteins

    Författare :Dimitra Peirasmaki; Staffan Svärd; Steven Singer; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Giardia; intestinal parasite; parasite infection; host-parasite interaction; virulence factors; HCMPs; cysteine-rich proteins; secretome; proteome;

    Sammanfattning : Giardia intestinalis is a eukaryotic parasite that colonizes the small intestine of humans and animals causing the diarrheal disease known as giardiasis. This parasite is not invasive and does not internalize into host cells but it rather attaches to the brush border surface of the small intestine disrupting the epithelial barrier. LÄS MER

  5. 5. Host molecular determinants of toxoplasma gondii dissemination

    Författare :Jonas Fuks; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Humans and animals acquire the parasite Toxoplasma gondii through contaminated food or water, upon which the parasite rapidly disseminates in the host. In immunocompetent individuals, this acute phase is transient and leads to chronic colonization of preferentially the central nervous system (CNS). LÄS MER
