  1. 1. Molecular epidemiology of coagulase-negative staphylococci in hospitals and in the community

    Författare :Micael Widerström; Johan Wiström; Tor Monsen; Anders Sjöstedt; Bo Söderquist; Umeå universitet; []

    Sammanfattning : Background Coagulase-negative staphylococci (CoNS) and in particular Staphylococcus epidermidis have emerged as major pathogens primarily causing nosocomial infections in patients with indwelling medical devices. These infections are often caused by multidrug-resistant strains of S. epidermidis (MDRSE). LÄS MER

  3. 2. Generic Properties of Polymer Solutions

    Författare :Takashi Uematsu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photon correlation spectroscopy; collective diffusion; atomic force microscopy; relaxation; agarose gel electrophoresis; DNA; Zimm dynamics; pulsed-field gradient NMR; superdiffusion; polymer solution; blob model; gel;

    Sammanfattning : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. LÄS MER

  4. 3. Detection and Characterisation of Salmonella in Animal Feed Samples by PCR-Based Methods

    Författare :Charlotta Löfström; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; Analytisk kemi; Analytical chemistry; mykologi; virologi; bakteriologi; Mikrobiologi; validation; Microbiology; bacteriology; virology; mycology; Salmonella; ribotyping; detection; animal feed; randomly amplified polymorphic DNA; pulsed-field gel electrophorsis; pre-PCR processing; PCR; polymerase chain reaction; genotyping;

    Sammanfattning : Animal feed is a recognised source of Salmonella enterica for farm livestock and may also indirectly cause infection in people consuming foods of animal origin. It is therefore important to have rapid, reproducible and specific methods for the detection of Salmonella in feed, and for the characterisation of strains for further epidemiological investigations or to trace the source of contamination in a production facility.

  5. 4. Postoperative mediastinitis : risk factors, wound contamination, diagnostic possibilities

    Författare :Catarina Yael Bitkover; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :postoperative mediastinitis; risk factors; coaglase-negative staphylococci; pulsed field gel electrophoresis; computed tomography; granulocyte scintigraphy; inflammation; postoperative infection; procalcitonin; sternotomy; heart surgery;

    Sammanfattning : The aim of these studies has been to investigate different aspects of postoperative mediastinitis. Radiological investigations and biochemical markers of infection and inflammation were examined, risk factors analyzed and spread of bacteria during operation studied. LÄS MER

  7. 5. Microbial ecology and virulence gene studies of the insect pathogen Bacillus thuringiensis

    Författare :Katarina Eskils; Malte Hermansson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Sammanfattning : Bacillus thuringiensis (Bt) is a spore-forming bacterium used as a bio-pesticide due to its insect toxicity. Bt was used as a model organism in a risk evaluation project. Prevalence, survival and spreading, as well as genome stability, putative virulence genes, and gene transfer were examined. Field release of a marked Bt subsp. LÄS MER
