  1. 1. Studies on surface proteins of Gram-positive bacteria

    University dissertation from Center for Molecular Biomedicine, Lund University

    Author : Robert Janulczyk; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ABC transport; complement; surface protein; Gram-positive; Streptococcus pyogenes; Streptococcus pneumoniae; Klinisk biologi; Clinical biology;

    Abstract : Despite the availability of antibiotics and modern health care, infectious diseases continue to cause great suffering and costs. Bacterial surface proteins are important for the interaction between host and pathogen. READ MORE

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

    University dissertation from Center for Molecular Biomedicine, Lund University

    Author : Anna Martner; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gram-positive; Gram-negative bacteria; Streptococcus pneumoniae; IL-12; autolysin; pneumolysin; CD4 T cells; monocytes macrophages; dendritic cells;

    Abstract : 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. READ MORE

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

    University dissertation from Center for Molecular Biomedicine, Lund University

    Author : Susann Skovbjerg; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gram-positive; Gram-negative; bacteria; cytokines; monocytes macrophages; phagocytosis; Streptococcus pneumoniae; autolysin; acute otitis media; secretory otitis media; children; probiotics;

    Abstract : 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. READ MORE

  4. 4. Extracellular electron transfer features of the Gram-positive bacterium Enterococcus faecalis

    University dissertation from Media-Tryck, Lund University, Sweden

    Author : Galina Pankratova; [2018-10]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gram-positive bacteria; Enterococcus faecalis; Extracellular electron transfer; Electron-conducting redox polymers; Mediated electron transfer;

    Abstract : Electroactive microorganisms possess the unique ability to transfer electrons to or from a solid phase electron conductor, e.g., electrodes or minerals, through various physiological mechanisms. READ MORE

  5. 5. Genetics of Tetrapyrrole Synthesis in Gram-Positive Bacteria

    University dissertation from Department of Microbiology, Lund University

    Author : Per Johansson; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; siroheme; tetrapyrrole synthesis; Bacillus subtilis; Bacillaceae; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The organization and regulation of genes for tetrapyrrole synthesis were studied in low G+C Gram-positive bacteria. Clusters of genes encoding enzymes for tetrapyrrole biosynthesis were cloned from Bacillus sphaericus, Bacillus stearothermophilus, Brevibacillus brevis and Paenibacillus macerans. READ MORE
