  1. 1. Inflammatory mediator response to Gram-positive and Gram-negative bacteria in vitro and in middle ear infections

    Författare :Susann Skovbjerg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Gram-positive; Gram-negative; bacteria; cytokines; monocytes macrophages; phagocytosis; Streptococcus pneumoniae; autolysin; acute otitis media; secretory otitis media; children; probiotics;

    Sammanfattning : Based on the structure of the cell wall, bacteria are divided into Gram-positive and Gram-negative. While the cell wall of Gram-positive bacteria is thick, the cell wall of Gram-negatives is very thin and surrounded by an outer membrane with LPS. LÄS MER

  2. 2. Antibiotic uptake in Gram-negative bacteria

    Författare :Claudio Muheim; Daniel Daley; Jean-Marie Pagès; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Gram-negative bacteria; Antibiotic uptake; Outer membrane; Lipopolysaccharide; biokemi; Biochemistry;

    Sammanfattning : The increasing emergence and spread of antibiotic-resistant bacteria is a serious threat to public health. Of particular concern are Gram-negative bacteria such as Escherichia coli, Acinetobacter baumannii, Klebsiella pneumoniae or Pseudomonas aeruginosa. LÄS MER

  3. 3. Dendritic cell interactions with Gram negative bacteria

    Författare :Mattias Svensson; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mycology; virology; Major histocompatibility complex molecules; Dendritic cells; Gram negative bacteria; Antigen processing; Antigen presentation; bacteriology; Microbiology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The interaction between murine bone marrow-derived dendritic cells (DC) and the Gram negative bacteria Salmonella typhimurium and Escherichia coli have been characterised. These studies showed that DC phagocytosed and processed S. typhimurium and E. LÄS MER

  4. 4. Regulation of innate and adaptive immune responses by Gram-positive and Gram-negative bacteria

    Författare :Anna Martner; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Gram-positive; Gram-negative bacteria; Streptococcus pneumoniae; IL-12; autolysin; pneumolysin; CD4 T cells; monocytes macrophages; dendritic cells;

    Sammanfattning : Bacteria are classified as Gram-positive or Gram-negative, depending on their cell wall structure. The role of the bacterial cell wall in immune regulation is the focus of the current work. Most Gram-positive bacteria stimulate monocytes to produce large amounts of IL-12. LÄS MER

  5. 5. Studies on Polysaccharides from some Gram-Negative Bacteria

    Författare :Kurt Samuelsson; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; bacteria; chemical methods; food infections; polysaccharides; salmonella; Information Systems; Informatik;

    Sammanfattning : In this survey structural studies on some polysaccharides isolated from the families of Enterobachteriaceae (Klebsiella and Salmonella) and Parvobacteriaceae (Yersinia) will be discussed. The occurence of some rare or not earlier reported deoxysugars is demonstrated, namely, 6-deoxy-D-manno-heptose, 3-deoxy-L-glycero-pentulosonic acid and five of the isomers of 3,6-dideoxy-hexoses.
