1. Bacteria-host cell interactions : Studies on initial colonization, antimicrobial peptides, and biofilms
Abstract : The obligate human pathogen Neisseria meningitidis asymptomatically colonizes the upper respiratory tract, but crossing of the epithelial barrier can cause life-threatening meningitis and/or sepsis. N. READ MORE

2. Effects of Vibrio cholerae protease and pigment production on environmental survival and host interaction
Abstract : Only two out of more than 200 V. cholerae serogroups, classified on the basis of LPS structure, are associated with epidemic or pandemic cholera. These toxigenic serogroups carry phage-derived pathogenicity islands coding for the main virulence factors for establishment of cholera disease – cholera toxin (CTX) and toxin-coregulated pilus (TCP).

3. Roles of secreted bacterial factors in modulation of host cell signalling
Abstract : Pathogenic bacteria employ several secretion systems to release or inject virulence factors that may alter host cell processes, generate a replicative niche, and aid bacterial survival in adverse environments. This thesis presents my investigations on how bacterial factors can modulate host cell signalling mechanisms. READ MORE

4. Exploring the interaction between the human microbiota and infections
Abstract : The microbiota is a living ecosystem that is influenced by a variety of host and environmental factors. Distinct microbiota colonizes various body sites, such as the gastrointestinal system and vaginal tract, corresponding to the unique microenvironment. A healthy gut microbiota contains a stable, balanced, and highly diverse reservoir of microbes. READ MORE

5. Characterisation of surface traits of Helicobacter pylori and their role in the infectious process
Abstract : 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.
