  1. 1. Immunity to Salmonella infection

    Författare :Cecilia Johansson; Lund University.; Lunds universitet.; [2002]
    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

  2. 2. Importance of wild birds in the spread of Salmonella

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Helena Palmgren; Umeå universitet.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; wild birds; Black-headed gull; Peregrine falcon; Antarctica; penguins; seals; PFGE; IS200; salmonella carriage;

    Sammanfattning : Salmonella is one of the most important enteropathogenic bacteria. It is responsible for about 5000 reported cases of human gastroenteritis each year in Sweden. Salmonellosis is a zoonotic disease, and the bacterium has the ability to infect a variety of both domestic and wild animal species. LÄS MER

  3. 3. Presentation of Salmonella antigens by dendritic cells

    Detta är en avhandling från Ulf Yrlid, Fredsgatan 2, 222 20 Lund

    Författare :Ulf Yrlid; Lund University.; Lunds universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; Immunology; antigen processing and presentation; Dendritic cells; Salmonella; transplantation; Immunologi; serologi;

    Sammanfattning : This study investigates the interaction between dendritic cells (DC) and the Gram negative intracellular bacterium Salmonella typhimurium. Using in vitro and in vivo approaches, the capacity of DC to directly and indirectly present antigens from Salmonella-infected cells, cytokine production by infected DC, and activation of bacteria-specific T cells was analyzed.

  4. 4. Salmonella in pigs

    Detta är en avhandling från Ulf Yrlid, Fredsgatan 2, 222 20 Lund

    Författare :Julia Österberg; Sveriges lantbruksuniversitet.; [2010]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In recent years several incidents of feed-borne spread of Salmonella spp. have been documented in Swedish pig herds, including serotypes previously not associated with pigs. In this thesis two feed-associated serotypes (S Cubana and S Yoruba) were compared with two serotypes commonly detected in pigs (S Typhimurium and S Derby). LÄS MER

  5. 5. Recruitment, Differentiation, and Function of monocytes during Salmonella infection

    Detta är en avhandling från Ulf Yrlid, Fredsgatan 2, 222 20 Lund

    Författare :Anna Rydström; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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
