    Sammanfattning : Salmonella enterica serovar Typhimurium (S.Tm) causes enterocolitis with significant worldwide morbidity and mortality. The general aim of this thesis is to investigate variation in host cell invasion mechanisms used by S.Tm across different host cell contexts, as well as the influence of bacterial cell-cell heterogeneity on invasion-relevant S.

  4. 8. Characterization of c-di-GMP signaling in Salmonella typhimurium

    Författare :Roger Simm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Signal transduction via cyclic nucleotides is a general mechanism utilized by cells from all kingdoms of life. Identification of cyclic diguanosine monophosphate (c-di-GMP) as an allosteric activator of the cellulose synthase in Gluconacetobacter xylinus 20 years ago, paved the way for the discovery of a novel general signalling system which is unique to bacteria.

  7. 10. Virulence of Salmonella enterica serovar typhimurium and innate antibacterial host responses

    Författare :Eva Bjur; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Salmonella; LPS; macrophages; NOS; SPI-2; thioredoxin; TrxA; TRAPC;

    Sammanfattning : The bacterial species Salmonella enterica consists of a collection of closely related enteric bacteria giving rise to diverse diseases in a wide range of hosts. In the murine infection model Salmonella enterica serovar Typhimurium (S. Typhimurium) causes an invasive disease which in many aspects resembles human typhoid fever. LÄS MER
