  1. 16. Glucosyl transferase gene(s) of temperate bacteriophages SfX and SfV and their role in the modification of the O-antigen of Shigella flexneri

    Författare :Pham Thi Huan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Shigella flexneri is the main cause of bacillary dysentery in developing countries with a high attack rate and mortality in young children. Thus developing a S. flexneri vaccine has been given priority by WHO. It has been documented that Shigella lipopolysaccharide (LPS) is highly immunogenic. LÄS MER

  3. 17. Dendritic cell interactions with Gram negative bacteria

    Författare :Mattias Svensson; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mycology; virology; Major histocompatibility complex molecules; Dendritic cells; Gram negative bacteria; Antigen processing; Antigen presentation; bacteriology; Microbiology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The interaction between murine bone marrow-derived dendritic cells (DC) and the Gram negative bacteria Salmonella typhimurium and Escherichia coli have been characterised. These studies showed that DC phagocytosed and processed S. typhimurium and E. LÄS MER

  4. 18. The biological cost of resistance to antibiotics

    Författare :Johanna Björkman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; mikrobiologi; Microbiology;

    Sammanfattning : The rate of development and stability of antibiotic resistance are determined by several factors including (i) the mutation rate, (ii) the fitness costs of resistance, and (iii) the ability of bacteria to genetically compensate for such costs.. This study has focused on the experimental measurement of these parameters in antibiotic-resistant S. LÄS MER

  5. 19. Adaptation of Salmonella enterica to antibiotics and innate immunity effectors

    Författare :Kim Vestö; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  7. 20. Genetic adaptation of salmonella enterica to phagocytic cells

    Författare :Sofia Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Salmonella; macrophages; host-adaptation; microarray; nitric oxide;

    Sammanfattning : 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. LÄS MER
