  2. 16. Wastewater discharges and microbial variability in a surface water source

    Author : Johan Åström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; faecal indicators; pathogens; drinking-water; microbial risk assessment; variability; rainfall; catchment; wastewater; surface water; Hazardous events;

    Abstract : Planning for drinking-water safety in surface waters includes a systematic assessment of hazards in the catchment, and microbial contamination is considered a major health risk. The aim of this thesis was to identify and characterize microbial hazardous events reported for River Göta älv, Sweden. READ MORE

  4. 17. Perturbation of the epithelial barrier by enteric pathogens

    Author : Farideh Tafazoli; Magnusson Karl-Eric; Hakon Leffler; Linköpings universitet; []
    Keywords : enteric pathogens: signal transduction; barrier function; MEDICINE; MEDICIN;

    Abstract : Gastrointestinal infections in humans have been associated with a number of diseased condition, including stomach ulcers, gastroenteritis, Crohn's disease, and rheumatic arthritis. Such infections often cause altered intestinal permeability through perturbation of the tight junctions that hold epithelial cells together. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 19. Lactobacilli expressing antibody fragments against pathogens

    Author : Anna Hultberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Adherence to mucosal surfaces has been shown to be of great importance in the pathogenesis of various infections in the gastro-intestinal tract. Live recombinant bacteria can be used to deliver active or passive immunity at the mucosal surface, which is the site of entry for the majority of the pathogens. READ MORE

  7. 20. Lactobacillus mediated targeting of gastrointestinal pathogens

    Author : Kasper Krogh Andersen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The mucosal membranes of the gastrointestinal, genitourinary and respiratory tract are the main targets for infection in the human body and are repeatedly challenged by pathogens. Passive immunization using delivery of antibodies at the mucosal membrane may thus provide a new first line of defense against these pathogens. READ MORE
