  1. 1. Managing agricultural nutrient leaching within the EC Water Framework Directive in Sweden

    Författare :Anna-Lena Bratt; Per Sandén; Martin Ljung; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nutrient leaching; agricultural pollution; C Water Framework Directive; water quality; legislation; övergödning; lantbruk; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : Agricultural management practices geared towards reducing nutrient leaching are in focus for the research presented in this thesis. Critical measures for reducing diffuse pollution from the agricultural sector depend on decisions of individual farmers. LÄS MER

  3. 2. Genotypic and phenotypic characterisation of Staphylococcus epidermidis isolated from prosthetic joint infections

    Författare :Bengt Hellmark; Bo Söderquist; Magnus Unemo; Åsa Nilsdotter; Tor Monsén; Örebro universitet; []
    Nyckelord :Staphylococcus epidermidis; prosthetic joint infections; antibiotic susceptibility; virulence factors; epidemiology; MLST; agr; SCCmec; MEDICINE; MEDICIN; Biomedicin; Biomedicine;

    Sammanfattning : Staphylococcus epidermidis has emerged in recent years as an important nosocomial pathogen, especially in infections associated with implanted foreign body materials (e.g., prosthetic joints and heart valves) and in individuals with a compromised immune system (e.g. LÄS MER

  4. 3. 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.

  5. 4. The accessory gene regulator, agr, a system for coordinate control of virulence genes in Staphylococcus aureus

    Författare :Eva Morfeldt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Bacterial pathogenicity is generally multifactorial, and genes encoding virulence factors are often subject to coordinate regulation. The regulating systems are supposed to adapt the production of virulence factors in response to changes in the environment during the process of infection. LÄS MER

  7. 5. 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
