  1. 6. YopD translocator function in Yersinia pseudotuberculosis type III secretion

    Författare :Tiago R. D. Costa; Matthew S. Francis; William D. Picking; Umeå universitet; []
    Nyckelord :Y. pseudotuberculosis; T3SS; translocon; YopD; coiled-coil; effector delivery; regulation; virulence; mikrobiologi; Microbiology;

    Sammanfattning : Type III secretion systems (T3SS) are a common feature of Gram-negative bacteria, allowing them to inject anti-host effectors into the interior of infected eukaryotic cells. By this mechanism, these virulence factors help the bacteria to modulate eukaryotic cell function in its favor and subvert host innate immunity. LÄS MER

  3. 7. Foodborne Virulence: Staphylococcus aureus Enterotoxins A and D

    Författare :Nina Wallin; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental factors; phage-encoded virulence; in vivo; enterotoxin D; enterotoxin A; gene expression; Staphylococcus aureus; virulence;

    Sammanfattning : The development of new, minimally processed food products challenges traditional concepts of food safety. How pathogenic bacteria behave in these new matrices is not known. To fill this knowledge gap and enable the production of food that is safe for the consumer, more information on virulence expression of pathogens in food matrices is required. LÄS MER

  4. 8. RNA-mediated virulence gene regulation in the human pathogen Listeria monocytogenes

    Författare :Edmund Loh; Jörgen Johansson; Nancy Freitag; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Listeria monocytogenes; virulence; ncRNAs; PrfA; 5´-UTRs; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The Gram-positive human pathogen Listeria monocytogenes uses a wide range of virulence factors for its pathogenesis. The majority of its virulence genes are encoded on a 9-kb pathogenicity island and are controlled by the transcriptional activator PrfA. LÄS MER

  5. 9. Temperature-inducible and calcium-regulated proteins encoded by the virulence plasmid of Yersinia

    Författare :Ingrid Bölin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia; virulence plasmid; gene products; regulation; calcium; temperature; outer membrane proteins;

    Sammanfattning : The pathogenic members of the genus Yersinia, Y. pseudotuberculosis, Y. pestis and Y. enterocolitica are transmitted from animals to man and may give rise to disease with a variety of symptoms. LÄS MER

  7. 10. Multiple functions of YopN in the Yersinia pseudotuberculosis type III secretion system : from regulation to in vivo infection

    Författare :Sarp Bamyaci; Åke Forsberg; Edouard Galyov; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Type III secretion system; Yersinia; YopN; virulence; phagocytosis; mouse infection; secretion kinetics;

    Sammanfattning : The type 3 secretion systems (T3SSs) are virulence mechanisms used by various Gram-negative bacteria to overcome the host immunity. They are often target-cell contact induced and activated. Activation results in targeting of virulence effector substrates into host cells. LÄS MER
