  1. 1. Host-bacteria interactions Host cell responses and bacterial pathogenesis

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Nele de Klerk; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Host-bacteria interaction; Helicobacter pylori; Neisseria gonorrhoeae; Lactobacillus; Epithelial cells; Macrophages; EGR1; Amphiregulin; SabA; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Helicobacter pylori colonizes the human stomach, where it causes gastritis that may develop into peptic ulcer disease or cancer when left untreated. Neisseria gonorrhoeae colonizes the urogenital tract and causes the sexually transmitted disease gonorrhea. READ MORE

  2. 2. Dynamic Organization of Molecular Machines in Bacteria

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Bhupender Singh; Uppsala universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular machines; bacteria; cell cycle; ribosome; replisome; divisome; spore; E. coli; H. pylori; Mycobacteria; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi; Mikrobiologi; Microbiology;

    Abstract : Bacterial cells were once treated as membrane-enclosed bags of cytoplasm: a homogeneous, undifferentiated suspension in which polymers (proteins, nucleic acids, etc.) and small molecules diffused freely to interact with each other. READ MORE

  3. 3. Environmental filtering of bacteria in low productivity habitats

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Inga Richert; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bacteria; environmental filtering; diversity; ecosystem service; hydrocarbon utilization; Southern Ocean; sediment; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Microbes fulfill important ecosystem functions by contributing as drivers of global nutrient cycles. Their distribution patterns are mainly controlled by environmental heterogeneities. So far, little is known about the mode of action of particular environmental drivers on the microbiota, particularly in low productivity habitats. READ MORE

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

    University dissertation from Stockholm : Institutionen för organisk kemi, Stockholms Universitet

    Author : Kurt Samuelsson; [1973]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacteria; chemical methods; food infections; polysaccharides; salmonella; Information Systems; Informatik;

    Abstract : 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.

  5. 5. Interaction Between Drosophila melanogaster mbn-2 Cells and Bacteria

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karin Johansson; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Drosophila; innate immunity; bacteria; host - pathogen interaction; Cellbiologi; NATURAL SCIENCES Biology Cell and molecular biology Cell biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Cellbiologi;

    Abstract : Innate immunity relies on a repertoire of germline-encoded non-rearranging pattern recognition receptors that bind to invariant microbial surface molecules. This event initiates a number of signal transduction cascades that lead to humoral and cellular defense responses like synthesis of antimicrobial peptides, phagocytosis and coagulation – mechanisms that efficiently fight infectious microorganisms and have been evolutionary conserved to exist in parallel with the antibody-based adaptive immunity found in vertebrates.
