1. 11. Exploring the interaction between the human microbiota and infections

   Författare :Liqin Cheng; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : 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. LÄS MER

3. 12. Regulation of bacterial adaptive behavior by the second messenger cyclic-di-GMP and host components

   Författare :Soazig Le Guyon; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : To optimize survival and growth, bacteria have evolved adaptive behaviors that respond to relevant environmental signals. A switch from the motile to the sessile lifestyle is probably the most ancient behavioral transition of microorganisms. LÄS MER

4. 13. Colonization, persistence and virulence factors in Escherichia coli strains in the human intestinal microflora

   Författare :Forough Nowrouzian; Göteborgs universitet; []
   Nyckelord :Escherichia coli; large intestine; infant; newborn; bacterial adhesins; hemolysins;

   Sammanfattning : Escherichia coli is a member of the normal intestinal microflora of man and many animals. In this thesis, various aspects of the E. coli colonization pattern were studied, especially the role of so called virulence factors for persistence of E. coli in the gut microflora. LÄS MER

5. 14. The human gastric microbiota in health and disease

   Författare :Mathilda Lindberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The human body comprises of complex microbial ecosystems that have co-evolved with its host and play important roles in the maintenance of health and in the etiology and outcome of various disease states. The microbiota that resides in the stomach has not been completely identified, and focus has previously been mainly on the gastric pathogen Helicobacter pylori. LÄS MER

7. 15. Influence of the microflora on gastrointestinal nitric oxide generation : studies in newborn infants and germ-free animals

   Författare :Tanja Sobko; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Nitrite; nitrate; IBD; lactobacilli; probiotics; germ-free; SCFA; H 2; newborn infants;

   Sammanfattning : Interactions between intestinal bacteria and the host play an important role in physiological regulation of gut function and in development of various diseases. Nitric oxide (NO) exhibits a variety of biological actions in the gut including regulation of regional blood flow, gut motility, water and electrolyte transport and immunity. LÄS MER
