  1. 1. Serological classification and genetic characterization of clinical isolates of Neisseria gonorrhoeae

    Författare :Marianne Bäckman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Neisseria gonorrhoeae; serotyping; antibiotic susceptibility; plasmid; pilC; auxotyping; fingerprinting; geographical origin;

    Sammanfattning : Neisseria gonorrhoeae is the etiologic agent of gonorrhoea, one of the oldest and most widespread of human infections. The development of methods to characterize the bacterium is of central importance in the control of the disease. One aim of this thesis was to evaluate serotyping of N. LÄS MER

  3. 2. Characterization of surface components of Moraxella catarrhalis and pathogenic Neisseria

    Författare :Motiur Rahman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Moraxella catarrhalisantibody LPS NeisseriapiliPilC;

    Sammanfattning : Infection is a multistep process including adhesion, colonisation, invasion and multiplication which finally results in disease. Bacterial surface components and virulence factors are essential for all these different steps and they are co-ordinately regulated during the different steps of pathogenesis and infection. LÄS MER

  4. 3. Molecular studies of Neisseria : host cell interactions

    Författare :Anne Rytkönen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The Neisseria family includes many non-pathogenic species but also two strict human pathogens; Neisseria gonorrhoeae and Neisseria meningitidis. Both organisms colonise mucosal surfaces and may cause disseminated infections upon passage of the epithelial barrier. LÄS MER

  5. 4. Molecular and cellular mechanisms during adherence and cell signaling of pathogenic Neisseria to host cells

    Författare :Helena Källström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Neisseria; pili; adhesion; PiIC; CD46; signaling; G-protein;

    Sammanfattning : The pathogenic members of the genus Neisseria include N. gonorrhoeae and N. meningitidis. Both organisms are obligate human pathogens that colonize mucosal surfaces. LÄS MER

  7. 5. Identification of new virulence factors in Francisella tularensis

    Författare :Anna-Lena Forslund; Åke Forsberg; Elisabeth Carniel; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Francisella tularensis; regulation; virulence; Hfq; DsbA; type IV pili; membrane; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Francisella tularensis, the causative agent of tularemia, is a highly virulent bacterium with an infection dose of less than ten bacteria. The ability of a pathogen to cause infection relies on different virulence mechanisms, but in Francisella tularensis relatively few virulence factors are known. Two F. LÄS MER
