  1. 21. Host responses and bacterial virulence factors in Neisseria infections

    Författare :Linda Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Neisseria; CD46; LPS; antimicrobial peptide.;

    Sammanfattning : Neisseria meningitidis and Neisseria gonorrhoeae are human specific pathogens. N. meningitidis is a major cause of meningitis and sepsis, whilst N. gonorrhoeae causes many millions of cases of gonorrhea in the world every year. LÄS MER

  3. 22. Virulence determinants of the insect pathogen Bacillus thuringiensis; : Molecular characterization of flagellins and the virulence protease immune inhibitor A

    Författare :Ann Lövgren; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Sammanfattning : Bacillus thuringiensis (Bt) is a motile, Gram positive, rod-shaped and spore-forminginsect pathogenic bacterium found on plants and in soil. The main insecticidal activityresides in a proteinacious crystal inclusion body (the S-endotoxin), but also the sporesare important for lethality. LÄS MER

  4. 23. Escherichia coli Fimbriae, Bacterial Persistence and Host Response Induction in the Human Urinary Tract

    Författare :Göran Bergsten; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; IL-8; IL-6; neutrophils; GFP; mucosal host response; Type 1 fimbriae; P fimbriae; adherence; virulence factors; regulation; deliberate colonisation; Escherichia coli 83972; Urinary tract infection; asymptomatic bacteriuria;

    Sammanfattning : Urinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine. LÄS MER

  5. 24. Studies on cell wall-attached proteins of Streptococcus pyogenes

    Författare :Magnus Rasmussen; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insertion sequence; phase variation; collagen-like; alpha2-macroglobulin; pattern; virulence; surface protein; Stretococcus pyogenes; cell wall-attached protein; Clinical biology; Klinisk biologi;

    Sammanfattning : Cell wall-attached proteins (CWPs) are important for the virulence of Gram-positive bacteria, but are also targets for the host immune system. CWPs have a conserved COOH-terminal region, responsible for cell wall-sorting. A pattern based on this conserved region was developed. LÄS MER

  7. 25. Identification and characterization of novel virulence factors in Streptococcus pneumoniae

    Författare :Florian Wartha; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Streptococcus pneumoniae (the pneumococcus) is a major human pathogen with high morbidity and mortality worldwide. Increased antibiotic resistance and insufficient vaccination contribute to the re-emerging of this pathogen. LÄS MER
