  1. 21. Microbiological food safety of cheese produced in Swedish small-scale dairies : characteristics, growth and enterotoxin production of Staphylococcus aureus

    Författare :Åsa Rosengren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The number of small-scale dairies in Sweden has increased during the past decade. Current agricultural policy encourages such small-scale production and various ways to help producers have been proposed. Combining traditional cheese making and good product safety is a challenge, since several human pathogens pose a hazard in the products. LÄS MER

  3. 22. Lactobacilli- and Staphylococcus aureus mediated modulation of immune responses in vitro

    Författare :Yeneneh Haileselassie; Eva Sverremark-Ekström; Huub Savelkoul; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lactobacilli; staphylococcus aureus; dendritic cells; retinoic acid; epithelial cells; T cells; immunologi; Immunology;

    Sammanfattning : The human gut harbors a vast number of microbes. These microbes are not passive bystanders. They are important in modulating the immune system. We have previously shown that early colonization with lactobacilli and Staphylococcus (S. LÄS MER

  4. 23. Immune maturation and lymphocyte characteristics in relation to early gut bacteria exposure

    Författare :Sophia Björkander; Eva Sverremark Ekström; Hanne Frøkiær; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Allergy; cell-free supernatant; chemokines; colonization; cytokines; FOXP3; immune-maturation; lactobacilli; lymphocytes; NK-cells; Staphylococcus aureus; unconventional T-cells; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : At birth, the immune system is immature and the gut microbiota influences immune maturation. Staphylococcus aureus (S. aureus) and lactobacilli are part of the neonatal gut microbiota and have seemingly opposite effects on the immune system. S. LÄS MER

  5. 24. Microbial ecology and virulence gene studies of the insect pathogen Bacillus thuringiensis

    Författare :Katarina Eskils; Malte Hermansson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Sammanfattning : Bacillus thuringiensis (Bt) is a spore-forming bacterium used as a bio-pesticide due to its insect toxicity. Bt was used as a model organism in a risk evaluation project. Prevalence, survival and spreading, as well as genome stability, putative virulence genes, and gene transfer were examined. Field release of a marked Bt subsp. LÄS MER

  7. 25. Influence of Lactic Acid Fermentation on Enteropathogenic Bacteria. Growth Inhibition in Cereal Gruels and in Human Intestine

    Författare :Rose Kingamkono; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intestinal mucosal permeability; enteropathogenic bacteria; enterotoxins; lactic acid fermentation;

    Sammanfattning : Togwa, a lactic-fermented cereal gruel, is widely consumed in Tanzania as a soft drink or used as a complementary food for young children. Studies were conducted to evaluate the potential of togwa to inhibit growth of common enteropathogenic bacteria and heat-labile (LT) enterotoxin production. LÄS MER
