1. Conservation ecology of the thick-shelled river mussel Unio crassus : The importance of parasite-host interactions
Sammanfattning : Unionoid mussels are globally threatened and their conservation requires species-specific knowledge on their ecology and parasite-host interaction. Unio crassus is one of Europe’s most threatened unionoid species and has a temporary obligate parasitic life stage (glochidia) on fish. LÄS MER
Sammanfattning : Plant feeding insects comprise about 25% of all animal species on earth and play an important role in all ecosystems. Although we understand that their association with plants is a key-factor driving the diversification in this group, we still have large gaps in our knowledge of the underlying processes of this relationship.

3. Characterisation of surface traits of Helicobacter pylori and their role in the infectious process
Sammanfattning : The surface appendages of bacteria determine the initial contact with host cells. Characterisation of functional organisation and spatial distribution of adhesive traits of outer membrane components of Gram-negative bacteria is a key issue in studies of the parasite-host cell interaction.

Sammanfattning : Giardia intestinalis is a eukaryotic parasite that colonizes the small intestine of humans and animals causing the diarrheal disease known as giardiasis. This parasite is not invasive and does not internalize into host cells but it rather attaches to the brush border surface of the small intestine disrupting the epithelial barrier. LÄS MER
Sammanfattning : Humans and animals acquire the parasite Toxoplasma gondii through contaminated food or water, upon which the parasite rapidly disseminates in the host. In immunocompetent individuals, this acute phase is transient and leads to chronic colonization of preferentially the central nervous system (CNS). LÄS MER
