  1. 11. Identification and Characterization of the Moraxella catarrhalis IgD-binding Protein MID

    Författare :Andrea Möllenkvist; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; receptor; structure; phase variation; MID; IgD; Moraxella catarrhalis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Moraxella catarrhalis is now an established human pathogen that frequently colonizes the upper respiratory tract causing most importantly otitis media in children. It has also been associated with sinusitis, laryngitis and lower respiratory tract infections in adults with predisposing conditions such as chronic obstructive pulmonary disease (COPD). LÄS MER

  3. 12. Synthesis of biologically active oligosaccharides of the Lewis b family and investigations towards the synthesis of glycoclusters

    Författare :Linnéa Skantz; Martina Lahmann; Thisbe Lindhorst; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Lewis b; lactosamine; dendrimers; oxazolidinone; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Sammanfattning : The gastric pathogen Helicobacter pylori is a Gram negative bacterium which may cause diseases such as peptic ulceration and gastric adenocarcinoma. It colonises a host by attaching to the gastric epithelial cells, an attachment mediated by outer membrane proteins on the bacterial surface, e.g, the blood group antigen binding adhesin, BabA.

  4. 13. Helicobacter pylori : molecular mechanisms for variable adherence properties

    Författare :Anna Vallström; Anna Arnqvist; Kristian Riesbeck; Umeå universitet; []
    Nyckelord :H. pylori; adherence; BabA; SabA; Leb; sLex; phase variation; recombination; vesicles;

    Sammanfattning : More than half of all people worldwide are infected with H. pylori. The infection always cause a gastric inflammation that may develop into peptic ulcer disease or gastric cancer. Attachment proteins, adhesins, mediate specific adherence of H. LÄS MER

  5. 14. 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.

  7. 15. Glycosphingolipid interactions of Helicobacter pylori and F1C-fimbriated Escherichia coli

    Författare :Niamh Roche; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; F1C fimbriae; Escherichia coli; glycosphingolipids; microbial adhesion; mass spectrometry;

    Sammanfattning : The aim of this thesis was to investigate glycosphingolipid interactions of the human pathogens Helicobacter pylori and F1C-fimbriated uropathogenic Escherichia coli. Of particular interest were interactions of H. pylori to complex gangliosides, the role played by H. LÄS MER
