1. Characterization and persistence of potential human pathogenic vibrios in aquatic environments
Sammanfattning : Vibrio spp., natural inhabitants of aquatic environments, are one of the most common causes of bacterial gastroenteritis in the world, being spread to humans via the ingestion of seafood, contaminated drinking water or exposure to seawater. The majority of Vibrio spp. are avirulent, but certain strains may sporadically be human pathogenic. LÄS MER

3. Effect of virulence factors on survival strategies of vibrio cholerae and vibrio mimicus
Sammanfattning : Vibrio is a genus of gram-negative bacteria comprising nearly 70 species and they are clinically human pathogens that can cause many infections. This study is mainly based on two species such as Vibrio cholerae O1 El Tor, which cause cholera disease and Vibrio mimicus, that cause gastroenteritis, open wounds infection, and septicemia. LÄS MER
4. 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.

5. Modulators of Vibrio cholerae predator interaction and virulence
Sammanfattning : Vibrio cholerae, the causal agent of cholera typically encodes two critical virulence factors: cholera toxin (CT), which is primarily responsible for the diarrhoeal purge, and toxin-co-regulated pilus (TCP), an essential colonisation factor. Nontoxigenic strains expressing TCP can efficiently acquire the CT gene through lysogenic conversion with CTXΦ, a filamentous phage that encodes CT and uses TCP as a receptor. LÄS MER
