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

    Detta är en avhandling från Lund University

    Författare :Nina Wallin; Lund University.; Lunds universitet.; [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

    Sammanfattning : Francisella tularensis, the causative agent of tularemia, is a highly virulent bacterium with an infection dose of less than ten bacteria. The ability of a pathogen to cause infection relies on different virulence mechanisms, but in Francisella tularensis relatively few virulence factors are known. Two F. LÄS MER

  3. 3. Virulence Factors and Motility Mechanisms of Pathogenic Neisseria

    Detta är en avhandling från Stockholm : Department of Genetics, Microbiology and Toxicology, Stockholm University

    Sammanfattning : Neisseria gonorrhoeae and Neisseria meningitidis are two closely related human specific pathogens. Neisseria gonorrhoeae is the causative agent for the sexually transmitted disease gonorrhea and often causes asymptomatic infections in women which is a cause of infertility. LÄS MER

    Sammanfattning : The common human pathogen Streptococcus pyogenes is the causative agent of numerous mild and severe clinical conditions. It expresses a number of secreted or cell wall-anchored proteins that modulate the human immune system and facilitate colonization and spread of the pathogen in the human host. During S. LÄS MER
