  1. 16. 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

  3. 17. Receptor Interactions Between Pathogenic Bacteria and Host Cells

    Författare :Lena Lövkvist; Ann-Beth Jonsson; Heiko Herwald; Uppsala universitet; []
    Nyckelord :Microbiology; Type IV pili; Lipooligosaccharide; ScpC protease; CD46; Mikrobiologi;

    Sammanfattning : This thesis focuses on host and pathogen specific interactions during invasive disease. We have investigated the role and impact of different virulence factors of Neisseria gonorrhoeae, N. meningitidis and Streptococcus pyogenes on host epithelial cells and in vivo. N. LÄS MER

  5. 19. Pathogenic Neisseria infections of human neutrophils and epithelial cells : focusing on host responses and immune evasion

    Författare :Niklas Söderholm; Helena Aro; Thomas Rudel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Neisseria gonorrhoeae; Neutrophils; PMN; Epithelial cells; Polarized cells; Type IV pili; Adherence; Cell cycle; DNA damage; Lactobacillus; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : N. meningitidis and N. gonorrhoeae are obligate human pathogens that colonize mucosal surfaces and are often carried asymptomatically. These bacteria have developed adhesive structures that promote adherence to host cells and efficient colonization of new hosts. LÄS MER
