  1. 36. Structural and functional studies of the secreted metalloprotease PrtV from Vibrio cholerae

    Författare :Aaron Edwin; Elisabeth Sauer-Eriksson; Helena Berglund; Umeå universitet; []
    Nyckelord :Cholera; Vibrio cholerae; virulence factors; PrtV; X-ray crystallography; NMR;

    Sammanfattning : Cholera, an acute diarrheal diseases caused by the intestinal infection of the pathogenic bacterium Vibrio cholerae, continues to be a global killer in the world today. PrtV, a secreted zinc metalloprotease, is a potent cytotoxic virulence factor of V. cholerae. LÄS MER

  3. 37. Antimicrobial peptides and virulence factors in meningococcal colonisation and disease

    Författare :Miriam Geörg; Ann-Beth Jonsson; Ole E. Sørensen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; antimicrobial peptide; LL-37; cell-penetrating peptide; resistance; polynucleotide phosphorylase; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The Gram-negative bacterium Neisseria meningitidis is a transient commensal of the human nasopharynx, but occasionally causes life-threatening disease. During colonisation of its niche, N. meningitidis has to overcome innate immune defences, including the expression of antimicrobial peptides (AMPs). LÄS MER

  4. 38. Neonatal invasive infections with focus on Group B streptococci

    Författare :Margrét Johansson Gudjónsdóttir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neonatal sepsis; Group B streptococci; Virulence factors;

    Sammanfattning : Invasive infections affect neonates with the risk of severe morbidity and death, and Streptococcus agalactiae (Group B streptococcus, GBS) remains one of the most common pathogens. The aim of this thesis was to assess infections among neonates and infants, focusing on GBS to better understand prevention and treatment. LÄS MER

  5. 39. Bacterial virulence or exorbitant host response? On innate immunity against the streptococcal M1 protein

    Författare :Sandra Persson; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skin infection; Streptococcus pyogenes; M1 protein; Innate Immunity; Host response; Virulence factor; Neutrophil recruitment; Heparin-binding protein HBP ; Leptospirosis;

    Sammanfattning : Bacterial infection is inevitable throughout a lifetime. What differs between mild andserious infections is the pathogen responsible and how the host immune systemresponds to it. A fundamental role to prevent infection is a proper physical barrier such as the skin and mucosa. LÄS MER
