  2. 1. Presentation of Salmonella antigens by dendritic cells

    Author : Ulf Yrlid; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; Immunology; antigen processing and presentation; Dendritic cells; Salmonella; transplantation; Immunologi; serologi;

    Abstract : 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.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Enteric fever; Salmonella; chronic carriers; metabolomics; diagnosis; biomarkers; multivariate data analysis; GCxGC-MS; GC-MS; LC-MS;

    Abstract : Enteric (or typhoid) fever is a systemic infection mainly caused by Salmonella Typhi and Salmonella Paratyphi A. The disease is common in areas with poor water quality and insufficient sanitation. Humans are the only reservoir for transmission of the disease. READ MORE

  5. 3. Genetic adaptation of salmonella enterica to phagocytic cells

    Keywords : Salmonella; macrophages; host-adaptation; microarray; nitric oxide;

    Abstract : Salmonella enterica is a collection of closely related enteric bacteria that as a species is capable of infecting a wide variety of hosts. S. enterica serovar Typhimurium, (S. Typhimurium), causes a systemic disease in mice which in many aspects resembles human typhoid fever caused by S. READ MORE

    Author : Kim Vestö; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Salmonella enterica is a bacterial pathogen causing major morbidity and mortality in low- and middle-income countries. The bacteria can cause a wide range of disease, ranging from the severe systemic disease typhoid fever to localized gastroenteritis. Characteristics of typhoid fever, caused by Salmonella enterica serovar Typhi (S. READ MORE

  7. 5. Pharmaceutical and mutational interference with virulence of Salmonella enterica serovar typhimurium

    Author : Aurel Negrea; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Within the species Salmonella enterica are a diverse range of bacteria that can cause illness in humans and many animals. Salmonellae are extremely versatile and can adapt to a variety of environments and hosts. Typhoid and paratyphoid fever, caused by human-restricted S. enterica serovars Typhi and Paratyphi are common in the developing world. READ MORE
