  1. 1. Foodborne Virulence: Staphylococcus aureus Enterotoxins A and D

    Detta är en avhandling från Lund University

    Författare :Nina Wallin; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental factors; phage-encoded virulence; in vivo; enterotoxin D; enterotoxin A; gene expression; Staphylococcus aureus; virulence;

    Sammanfattning : The development of new, minimally processed food products challenges traditional concepts of food safety. How pathogenic bacteria behave in these new matrices is not known. To fill this knowledge gap and enable the production of food that is safe for the consumer, more information on virulence expression of pathogens in food matrices is required. LÄS MER

  2. 2. Regulation of virulence gene expression in Staphylococcus aureus

    Detta är en avhandling från Stockholm : Karolinska Institutet, Microbiology and Tumor Biology Center (MTC)

    Författare :Karin Tegmark Wisell; Karolinska Institutet.; Karolinska Institutet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The pathogenic bacterium Staphylococcus aureus has the ability to cause a wide variety of human diseases, ranging from superficial abscesses and wound infections to deep and systemic infections such as osteomyelitis, endocarditis and septicaemia. The ability to cause disease has been attributed to a large number of toxins and digesting enzymes as well as to proteins at the bacterial surface that bind various host molecules. LÄS MER

  3. 3. RNA-mediated virulence gene regulation in the human pathogen Listeria monocytogenes

    Detta är en avhandling från Umeå, Sweden : Print & Media

    Författare :Edmund Loh; Jörgen Johansson; Nancy Freitag; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Listeria monocytogenes; virulence; ncRNAs; PrfA; 5´-UTRs; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The Gram-positive human pathogen Listeria monocytogenes uses a wide range of virulence factors for its pathogenesis. The majority of its virulence genes are encoded on a 9-kb pathogenicity island and are controlled by the transcriptional activator PrfA. LÄS MER

  4. 4. Extracellular serine proteases as virulence factors in nematophagous fungi: Molecular characterization and functional analysis of the PII protease in Arthrobotrys oligospora

    Detta är en avhandling från Microbial Ecology, Lund University

    Författare :Johan Åhman; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Aspergillus niger.; Heterologous expression; Over-expression; Gene-disruption; Transformation system; Serine protease; Biological control; Arthrobotrys oligospora; Fungi; Nematophagous; Biologi;

    Sammanfattning : Nematophagous fungi are parasites of nematodes, thus they have been considered and tested for biological control of parasitic nematodes, but so far with limited success. Due to the fact that the nematode cuticle is composed of proteins it is likely that fungal extracellular proteases are involved in the infection of nematodes. LÄS MER

  5. 5. Helicobacter spp. interactions with mucins: adhesion and mucin regulation of pathogen proliferation and gene expression

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Emma C Skoog; Göteborgs universitet.; Gothenburg University.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter; mucin; glycosylation; Lactobacillus; adhesion; proliferation; gene expression; CagA; SabA; BabA; ArsS; Fur;

    Sammanfattning : Helicobacter pylori colonizes the gastric mucosa of approximately half of the world’s population and is a risk factor for gastritis, peptic ulcers and gastric cancer. H. pylori is surrounded by, and adheres to, the heavily glycosylated mucins that build up the mucus layer. The carbohydrate structures on the mucins that act as ligands for H. LÄS MER
