  1. 6. Meticulous control of the T3SS of Yersinia is essential for full virulence

    Författare :Ann-Catrin Björnfot; Hans Wolf-Watz; Kelly T. Hughes; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Yersinia; type III secretion; YscU; substrate specificity switch; heat shock proteins; VagH; methyltransferase; virulence; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The type III secretion system (T3SS) of pathogenic Yersinia pseudotuberculosis is involved in virulence. The syringe-like secretion system spans both bacterial membranes and is responsible for the ability of Yersinia to transfer toxic proteins (Yop proteins) into the eukaryotic target cell. LÄS MER

  2. 7. 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

  3. 8. 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

  4. 9. Electric DNA chips for determination of pathogenic microorganisms

    Författare :Yanling Liu; Sven-Olof Enfors; Thomas Schweder; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric DNA chip array; fast determination; virulence genes; multiplexed gene detection; bacterial colony; ultrasonication; DNA fragmentation; Bacillus cereus; Biology; Biologi; Bioengineering; Bioteknik;

    Sammanfattning : Silicon-based electric DNA chip arrays were utilized to fast identify pathogenic microorganisms with respect to the capacity to produce toxins involved in foodborne poisoning and infections. Bacteria of the B. cereus and the enterohemorrhagic E. LÄS MER

  5. 10. RsbX and stress response in Listeria monocytogenes

    Författare :Ana Henriques de Oliveira; Jörgen Johansson; Cormac Gahan; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Listeria monocytogenes; SigB; stressosome; RsbX; phosphorylation; growth; competitiveness; motility; energetic cost; homeostasis; stress response; virulence; invasion; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Sammanfattning : Listeria monocytogenes is a ubiquitous foodborne Gram-positive bacterium. Despite being mainly a soil bacterium, it can reach the food processing environment and contaminate food destined for human consumption, causing outbreaks. LÄS MER
