1. Nucleic Acid Based Pathogen Diagnostics
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. Microbotryum violaceum on Silene dioica : understanding traits that influence plant-pathogen interactions
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. The streptococcal IgG degrading enzyme IdeS : studies on host-pathogen interactions
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. S. LÄS MER
4. Evolutionary Processes and Genome Dynamics in Host-Adapted Bacteria
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. LÄS MER
5. A molecular exploration of sensory responses in c. elegans
Sammanfattning : 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. LÄS MER
