  1. 1. Commensal microbes, immune reactivity and childhood inflammatory bowel disease

    Författare :Cecilia Barkman; Göteborgs universitet; []
    Nyckelord :Inflammatory bowel disease; IBD; Pediatric; Childhood; Microbiota; T cells; B cells; cytokine; IL-12; monocytes; phagocytosis; intracellular signaling pathway; Crohn s disease; ulcerative colitis; children; flora;

    Sammanfattning : Inflammatory bowel disease (IBD) is characterized by chronic and relapsing intestinal inflammation of unknown etiology, but immune activation by the commensal microbiota probably plays a major role. The two major categories of IBD are ulcerative colitis and Crohn’s disease. LÄS MER

  2. 2. Regulation of innate and acquired immunity in infants by commensal bacteria

    Författare :Helen Karlsson; Göteborgs universitet; []
    Nyckelord :intestinal microflora; commensal; antigen-presenting cells; dendritic cells; CD25 regulatory T cells; allergy; infants; Staphylococcus aureus;

    Sammanfattning : The incidence of atopic diseases in children is steadily increasing in the industrialised world along with an improved hygienic lifestyle. The gastrointestinal flora may be of specific importance for the proper maturation of the immune system and for the induction of tolerance, in which CD25+ regulatory T cells (Tregs) play a crucial role.

  3. 3. Microbial Responses to Antibiotics – Stability of Resistance and Extended Potential of Targeting the Folate Synthesis

    Författare :Maria Jönsson; Göte Swedberg; Steven Meshnick; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; sulfonamide resistance; macrolide; commensal flora; substrate channeling; folate synthesis; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Sammanfattning : Resistance to antimicrobials is an increasing problem in the world of today, and develops faster than man can counter. It is therefore of importance to study metabolic pathways in order to develop new antibiotics, but also to understand how resistance spreads and stabilizes in microbial populations. LÄS MER

  4. 4. Microbiota of the alimentary tract of children - implications for allergy and inflammatory bowel disease

    Författare :Fei Sjöberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gut flora; child; oral flora; allergy; duodenum; inflammatory bowel disease; culture; T-RFLP; pyrosequencing;

    Sammanfattning : Allergy, which is the most common chronic disease in Swedish children and adolescents, is associated with a high standard of living and Western lifestyle. According to the hygiene hypothesis, allergy is due to inadequate stimulation of the immune system by microbes during early childhood, leading to failed maturation of the immune system. LÄS MER

  5. 5. Staphylococcus aureus in the infantile bowel flora

    Författare :Erika Lindberg; Göteborgs universitet; []
    Nyckelord :Staphylococcus aureus; intestinal; microflora; superantigen; RAPD; bacteria; infants;

    Sammanfattning : The increasingly hygienic life-style in Western societies may not only have reduced infections, but may also have altered the composition of the commensal microflora, which may, in turn, have predisposed to e.g. allergy development. Here we investigated the first year s intestinal colonization pattern of a Swedish birth-cohort. LÄS MER
