  1. 11. Chemical genetics and immunomodulation in Salmonella enterica serovar typhimurium infection

    Författare :Speranta Banesaru; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Salmonella sp. are versatile bacteria that survive and replicate in a plethora of environmental niches and hosts, including humans. The illnesses caused by various serovars in humans range from mild gastroenteritis to severe systemic disease such as typhoid fever that still cause an important number of casualties especially in developing countries.

  3. 12. Mechanisms and Biological Costs of Bacterial Resistance to Antimicrobial Peptides

    Författare :Hava Lofton Tomenius; Dan I Andersson; Ørjan Samuelsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; antibiotic resistance; fitness cost; Salmonella Typhimurium; Staphylococcus aureus; bile; serum; pH response; growth rate; mice; phoP; pmrB; waaY; LPS; LL-37; defensins; membrane potential; Mikrobiologi; Microbiology;

    Sammanfattning : The global increasing problem of antibiotic resistance necessarily drives the pursuit and discovery of new antimicrobial agents. Antimicrobial peptides (AMPs) initially seemed like promising new drug candidates. Already members of the innate immune system, it was assumed that they would be bioactive and non-toxic. LÄS MER

  4. 13. Mechanisms of dendritic cell maturation induced by intracellular bacteria infection

    Författare :Miguel A. Tam; Göteborgs universitet; []
    Nyckelord :Listeria; Salmonella; dendritic cells; maturation; MyD88; IFN-? ?;

    Sammanfattning : Dendritic cells (DCs) are essential for the development of an immune response against pathogens such as Listeria monocytogenes and Salmonella typhimurium. This is mostly because of their unique capacity to stimulate naïve T cells. LÄS MER

  5. 14. Uptake and fate of pathogenic microbes in the blue mussel, Mytilus edulis

    Författare :Bodil Hernroth; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mytilus edulis; bivalve; immune response; lipopolysaccharide; LPS; antimicrobial peptide; gamma camera; radiolabelling; Salmonella typhimurium; sanitary safety; public health;

    Sammanfattning : Bivalves, like the blue mussel Mytilus edulis, are filter-feeders and can therefore accumulate high numbers of microbes from the surrounding water. These shellfish are considered the main risk for bringing pathogens from domestic outlets in the sea, back to the community. LÄS MER

  7. 15. Mechanisms of Antibiotic Resistance Evolution

    Författare :Michael Knopp; Dan Andersson; Anca Segall; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance evolution; Escherichia coli; Salmonella; porins; fitness; epistasis; strain-specificity; sub-MIC; de novo gene evolution;

    Sammanfattning : The continuing emergence and spread of antibiotic resistant bacteria are a threat to various applications in modern medicine and impose a strong economic burden on health systems. The development of new antibiotics is slow and cannot counterbalance the dissemination of resistant bacteria. LÄS MER
