  2. 1. Nucleic Acid Based Pathogen Diagnostics

    Author : Michael S. Akhras; Pål Nyrén; Nader Pourmand; Mats Nilsson; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. S. READ MORE

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

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

    Abstract : 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.

  7. 5. A molecular exploration of sensory responses in c. elegans

    Author : Longjun Pu; Changchun Chen; Simon Tuck; Sara I Wilson; Zhiyong Shao; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; C. elegans; sensation; CRISPR Cas9; G protein-coupled receptors; neuropeptides; acute hypoxia; pathogen; chemosensation; hydrogen sulfide; HIF-1; iron;

    Abstract : Sensation provides a pivotal ability, allowing animals to survive in complex environments. The cues sensed by animals are represented by external stimuli and internal signals. However, the mechanisms mediating sensations in molecular and cellular level are still not well-studied. In this thesis, by using free-living nematodes C. READ MORE
