1. 16. The mechanics of adhesion polymers and their role in bacterial attachment

   Författare :Johan Zakrisson; Magnus Andersson; Ramser Kerstin; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pili; optical tweezers; bacterial adhesion; fimbriae; uncoiling;

   Sammanfattning : Bacterial resistance to antibiotics is increasing at a high rate in both developing and developed countries. To circumvent the problem of drug-resistant bacterial pathogens, we need to develop new effective methods, substances, and materials that can disarm and prevent them from causing infections. LÄS MER

3. 17. The intestinal epithelium of salmonids : transepithelial transport, barrier function and bacterial interactions

   Författare :Fredrik Jutfelt; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Epithelial barrier function; smoltification; cortisol; osmoregulation; Aeromonas salmonicida; Atlantic salmon; rainbow trout; bacterial translocation; intestine; Ussing chamber; vegetable lipids;

   Sammanfattning : The salmonid intestinal epithelium is important for growth and health of the fish. The epithelium is exposed to a multitude of internal and external factors that can influence its function. LÄS MER

4. 18. Innate immunity to intracellular bacterial infections

   Författare :Christian Trumstedt; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Intracellular bacterial pathogens have developed mechanisms to enter and invade cells, to survive the immune response and to replicate inside the host. We studied the innate mechanisms that have evolved in the host to battle intracellular bacterial pathogens, such as the obligate intracellular Chlamydia pneumoniae and the facultative intracellular Listeria monocytogenes, which invade the respiratory and the gastrointestinal tracts in humans.

5. 19. Application of proximity Ligation for Detection of Proteins, Biomolecular Interactions, and Single Copies of Pathogens

   Författare :Sigrun Margret Gustafsdottir; Ulf Landegren; Per-Åke Nygren; Uppsala universitet; []
   Nyckelord :Molecular medicine; Proximity ligation; Cytokines; Microbial pathogens; Protein-DNA interactions; Drug screening; Molekylärmedicin;

   Sammanfattning : Proximity ligation is a recently established technique that can provide answers to questions about the concentration, localization, interactions, modifications and functions of proteins. The method enables sensitive protein measurements with a detection limit in the low femtomolar range in complex biological samples. LÄS MER

7. 20. Impact of Drinking Water Treatment and Pipe Biofilms on Bacterial Dynamics in the Distribution System

   Författare :Kristjan Pullerits; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drinking water treatment; Drinking water treatment plant; UV; Slow sand filter; Ultrafiltration; Drinking water distribution system; Biofilm; Biostability; Nitrification; Bacterial communities; Flow cytometry; Next-generation sequencing; 16S rRNA gene amplicon sequencing;

   Sammanfattning : This thesis addresses drinking water quality and microbiology in full-scale drinking water distribution systems (DWDSs). It examines how UV irradiation and slow sand filters (SSFs) alter the water bacteriome, and how the biofilm in the DWDS affects the drinking water quality. LÄS MER
