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

    Författare :Nina Wallin; Teknisk mikrobiologi; []
    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

  3. 2. Invasive Staphylococcus aureus infections

    Författare :Gunnar Jacobsson; Göteborgs universitet; []
    Nyckelord :Staphylococcus aureus; epidemiology; risk factors; clinical presentation; mortality; recurrence; sequelae; agr; serology; colonization;

    Sammanfattning : Staphylococcus aureus is a leading cause of septicaemia-related death. The aims of this thesis were to describe the epidemiology of invasive Staphylococcus aureus infections (ISA), the clinical course, and serological response in ISA in a prospective, population-based study.

  4. 3. Staphylococcus aureus toxins - Influence on food safety and animal health

    Författare :Yusak Budi Susilo; Teknisk mikrobiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Staphylococcus aureus; toxins; food safety; enterotoxin A SEA ; prophage life cycle; GFP reporter strain; flow cytometry; enterotoxin D SED ; accessory gene regulator agr ; bovine mastitis; enterotoxin C SEC ; toxic shock syndrome toxin-1 TSST-1 ;

    Sammanfattning : Staphylococcus aureus (S. aureus) is a notorious opportunistic foodborne pathogen and also a common cause of bovine mastitis. It is known to produce many different virulence factors, including various staphylococcal enterotoxins and toxic shock syndrome toxin-1 (TSST-1). LÄS MER

  5. 4. Food-Related Gram-Positive Bacteria: Enterotoxin A Expression in Staphylococcus aureus and a New Regulation Mechanism in Lactococcus lactis

    Författare :Rong Cao; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactococcus lactis; multiple inhibition kinetics; dehydrogenase; ATP; ADP; food factors; biopreservatives; staphylococcal food poisoning; SEA; prophage induction; enterotoxin A; Staphylococcus aureus;

    Sammanfattning : Staphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. LÄS MER

  7. 5. Staphylococcus aureus in the infantile bowel flora

    Författare :Erika Lindberg; Göteborgs universitet; []
    Nyckelord :Staphylococcus aureus; intestinal; microflora; superantigen; RAPD; bacteria; infants;

    Sammanfattning : The increasingly hygienic life-style in Western societies may not only have reduced infections, but may also have altered the composition of the commensal microflora, which may, in turn, have predisposed to e.g. allergy development. Here we investigated the first year s intestinal colonization pattern of a Swedish birth-cohort. LÄS MER
