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

    Author : Robert Janulczyk; Institutionen för experimentell medicinsk vetenskap; []
    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

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

    Author : Susann Skovbjerg; Göteborgs universitet; []
    Keywords : 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

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

    Author : Anna Martner; Göteborgs universitet; []
    Keywords : 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

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

    Author : Galina Pankratova; Biokemi och Strukturbiologi; []
    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

  7. 5. Exploring the mechanistic details of Gram-positive Type 4 Secretion Systems

    Author : Lena Lassinantti; Ronnie Berntsson; A. Elisabeth Sauer-Eriksson; Sjoerd Wanrooij; Samuel Wagner; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antimicrobial resistance; Horizontal gene transfer; Gram-positive bacteria; Type 4 Secretion Systems; Conjugation; Enterococcus faecalis; pCF10; PrgU; PcfF; PrgB; Biochemistry; biokemi;

    Abstract : Hospital acquired (i.e. nosocomial) infections and antibiotic resistance are large issues in the world today, with about 1.3 million people estimated to have died from antibiotic resistant infections in 2019 alone, and these problems are on the rise. READ MORE
