11. Twin-arginine translocation in Yersinia : the substrates and their role in virulence
Sammanfattning : Pathogenic Yersinia cause a manifold of diseases in humans ranging from mild gastroenteritis (Y. pseudotuberculosis and Y. enterocolitica) to pneumonic and bubonic plague (Y. LÄS MER
12. Stress response and virulence in Vibrio anguillarum
Sammanfattning : Bacteria use quorum sensing, a cell to cell signaling mechanism mediated by small molecules that are produced by specific signal molecule synthases, to regulate gene expression in response to population density. In Vibrio anguillarum, the quorum-sensing phosphorelay channels information from three hybrid sensor kinases VanN, VanQ, CqsS that sense signal molecules produced by the synthases VanM, VanS and CqsA, onto the phosphotransferase VanU, to regulate activity of the response regulator VanO.

13. Small Molecules as Tools in Biological Chemistry : Effects of Synthetic and Natural Products on the Type III Secretion System
Sammanfattning : The increasing use of antibiotics has led to a huge problem for society, as some bacteria have developed resistance towards many of the antibiotics currently available. To help find solutions to this problem we studied small molecules that inhibit bacterial virulence, the ability to cause disease. LÄS MER
14. Escherichia coli Fimbriae, Bacterial Persistence and Host Response Induction in the Human Urinary Tract
Sammanfattning : Urinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine. LÄS MER
15. Bacterial Regulation of Peripheral Immunity : Mechanistic insights from lactobacilli and Staphylococcus aureus
Sammanfattning : There is a constant cross-talk between our immune system and the colonizing microbiota. The gut resident bacteria produce a broad range of molecules with regulatory activities in both local and distal tissues. Staphylococcus (S. LÄS MER
