  1. 21. 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

  3. 22. Development and validation of a localized murine candidiasis model : The pathogenesis, chemotheraphy and defense mechanisms to Candida mastitis in the lactating mouse

    Författare :Faisal Abdi Guhad; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; Murine model; Candida albicans; Pathogenesis; Virulence factors; Amphotericin B; Fluconazole; Complement activation; C3c; SCID mice; Nude mice; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : A murine model of localized candidiasis (mastitis) was developed. The model was analyzed withrespect to its discriminative abilities through investigation of the virulence properties of C.albicans mutant strains compared with the wild-type parental strain. LÄS MER

  4. 23. Identification of Virulence Factors in Nematode-Trapping Fungi - Insights from Genomics, Transcriptomics and Proteomics

    Författare :Karl-Magnus Andersson; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nematode-trapping fungi; comparative genomics; comparative transcriptomics; proteomics; virulence factors; parasitism;

    Sammanfattning : Nematode-trapping fungi are soil-living organisms with the unique ability to capture and infect free-living nematodes. The interest in studying these fungi arises from their potential use as biological control agents for plant- and animal-parasitic nematodes. LÄS MER

  5. 24. 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

  7. 25. Mechanisms of P fimbriae cell activation

    Författare :Maria Hedlund; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; type 1 fimbriae; LPS; glycosphingolipids; ceramide; E. coli; P fimbriae; mucosa; cytokines; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Microbial attachment to host cells plays a central role in the induction of inflammatory responses and the production of the disease. Uropathogenic Gram negative bacteria carry surface lectins that specifically recognize oligosaccharide receptor epitopes expressed on glycolipids or glycoproteins. LÄS MER
