  1. 1. Nucleic Acid Based Pathogen Diagnostics

    Författare :Michael S. Akhras; Pål Nyrén; Nader Pourmand; Mats Nilsson; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; pathogen diagnostics; antibiotic resistance; connector inversion probes CIPer ; human papillomavirus HPV ; genotyping; global health diagnostic forum; molecular inversion probe MIP ; neisseria gonorrhoeae; padlock probes; pyrosequencing; Biochemistry; Biokemi;

    Sammanfattning : Pathogenic organisms are transmitted to the host organism through all possible connected pathways, and cause a myriad of diseases states. Commonly occurring curable infectious diseases still impose the greatest health impacts on a worldwide perspective. LÄS MER

  2. 2. Microbotryum violaceum on Silene dioica : understanding traits that influence plant-pathogen interactions

    Författare :Åsa Granberg; Barbara E. Giles; Ulla Carlsson-Granér; Arjen Biere; Umeå universitet; []
    Nyckelord :plant-pathogen interaction; biochemical resistance; breeding system; automixis; race specific resistance; extinction-colonisation dynamics; Silene dioica; Microbotryum violaceum;

    Sammanfattning : The dynamics of a plant-pathogen interaction vary both within and among species. Both spatial structuring and specific genetic and life-history characteristics will affect the interaction and the outcome of a potential co-evolution between the two organisms. LÄS MER

  3. 3. The streptococcal IgG degrading enzyme IdeS : studies on host-pathogen interactions

    Författare :Jenny Johansson Söderberg; Ulrich von Pawel-Rammingen; Jan Ingemar Flock; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; streptococcus pyogenes; IdeS; molekylärbiologi; Molecular Biology;

    Sammanfattning : The important human pathogen Streptococcus pyogenes causes both mild infections such as pharyngitis and impetigo but also severe life threatening invasive infections.  Specific antibodies (IgG) recognize pathogens and are important mediators for pathogen clearance by the immune defence.

  4. 4. Evolutionary Processes and Genome Dynamics in Host-Adapted Bacteria

    Författare :Björn Nystedt; Siv Andersson; David Guttman; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; molecular evolution; pathogen; secretion system; Bartonella; Buchnera; Blochmannia; Helicobacter; Bioinformatics; Bioinformatik; Evolutionary Genetics; evolutionär genetik;

    Sammanfattning : Many bacteria live in close association with other organisms such as plants and animals, with important implications for both health and disease. This thesis investigates bacteria that are well adapted to live inside an animal host, and describes the molecular evolutionary processes underlying host-adaptation, based on bacterial genome comparisons.

  5. 5. Risk-Based Decision Model for Microbial Risk Mitigation in Drinking Water Systems

    Författare :Viktor Bergion; Chalmers University of Technology; []
    Nyckelord :drinking water; quantitative microbial risk assessment; cost-benefit analysis; health risk; contaminant fate and transport modelling; economic valuation of health effects; pathogen;

    Sammanfattning : Microbial risks in drinking water systems can cause sporadic pathogenic infections and waterborne outbreaks resulting in large costs for society. In 2010 for example, around 27,000 persons were infected with Cryptosporidium in Östersund, Sweden. LÄS MER
