  1. 1. Aortic infections : The Nadir of Vascular Surgery

    Författare :Karl Sörelius; Anders Wanhainen; Kevin Mani; Björck Martin; Benjamin Ware Starnes; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mycotic; aortic; aneurysm; surgery; infection; endovascular repair; open abdomen; Kirurgi; Surgery;

    Sammanfattning : Aortic infections are rare, life-threatening and constitute a major challenge in surgical management. This thesis aims to evaluate short – and long-term outcome of endovascular aortic repair (EVAR) for mycotic aortic aneurysms (MAA) and the subsequent risk of recurrent infections, changes in surgical practice over time for abdominal MAAs in Sweden and outcome for different treatment modalities, as well as the risk of secondary vascular infection after treatment with Open abdomen after aortic surgery.

  3. 2. Immunity to Salmonella infection

    Författare :Cecilia Johansson; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; serology; transplantation; Immunologi; serologi; cytokines; antigen presentation; liver; dendritic cells; Salmonella; gram negative bacteria;

    Sammanfattning : The immune system has several strategies to combat infections. The present study investigates various aspects of the interaction between Gram negative bacteria, particularly Salmonella, and antigen presenting cells (APC). Salmonella is an intracellular bacterium infecting mice and man. LÄS MER

  4. 3. Recruitment, Differentiation, and Function of monocytes during Salmonella infection

    Författare :Anna Rydström; Göteborgs universitet; []
    Nyckelord :Salmonella; Monocyte; Neutrophil; Chemokine; Toll-like receptor; Differentiation;

    Sammanfattning : Monocytes are a heterogeneous population in the blood with an enormous plasticity whose fate and functions are dictated by the microenvironment. They are phenotypically and functionally related to neutrophils and dendritic cells (DCs) and share an overlapping expression pattern of surface molecules with these cells. LÄS MER

  5. 4. It Takes Two to Tango : Bacterial heterogeneity and host cell features govern Salmonella infection

    Författare :Viktor Ek; Mikael E. Sellin; Francisco García del Portillo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; swimming; swim pattern; targetting; virulence; invasion; host-pathogen interactions; epithelium; epithelial cells; macrophages; monocytes; monolayer; flagella; genome; genetic; barcoding; discreet-invasion; shape; morphology; antibiotics; persistence; Mikrobiologi; Microbiology;

    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.

  7. 5. Studies on Polysaccharides from some Gram-Negative Bacteria

    Författare :Kurt Samuelsson; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteria; chemical methods; food infections; polysaccharides; salmonella; Information Systems; Informatik;

    Sammanfattning : In this survey structural studies on some polysaccharides isolated from the families of Enterobachteriaceae (Klebsiella and Salmonella) and Parvobacteriaceae (Yersinia) will be discussed. The occurence of some rare or not earlier reported deoxysugars is demonstrated, namely, 6-deoxy-D-manno-heptose, 3-deoxy-L-glycero-pentulosonic acid and five of the isomers of 3,6-dideoxy-hexoses.
