  1. 1. Virulence determinants of the insect pathogen Bacillus thuringiensis; : Molecular characterization of flagellins and the virulence protease immune inhibitor A

    Författare :Ann Lövgren; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Sammanfattning : Bacillus thuringiensis (Bt) is a motile, Gram positive, rod-shaped and spore-forminginsect pathogenic bacterium found on plants and in soil. The main insecticidal activityresides in a proteinacious crystal inclusion body (the S-endotoxin), but also the sporesare important for lethality. LÄS MER

  3. 2. Electric DNA arrays for determination of pathogenic Bacillus cereus

    Författare :Yanling Liu; Sven-Olof Enfors; Helena Anderson; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacillus cereus; haemolysin; non-haemolytic enterotoxin; cytotoxin K-2; cereulide; toxin-coding genes; bacterial colony; electric DNA chip; ultrasonication; DNA fragmentation; Biochemistry; Biokemi;

    Sammanfattning : Silicon-based electric chip arrays were developed for characterization of Bacillus cereus with respect to the capacity to produce toxins involved in food poisoning and foodborne infections. Bacteria of the B. cereus group contain different sets of four toxins encoded by eight genes. LÄS MER

  5. 4. 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
