    Sammanfattning : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. LÄS MER

  2. 2. Identification of bacteria associated with malaria mosquitoes - Their characterisation and potential use

    Detta är en avhandling från Stockholm : Institutionen för genetik, mikrobiologi och toxikologi

    Författare :Jenny Lindh; Stockholms universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malaria; mosquito; Anopheles; bacteria; paratransgenics; semiochemicals; NATURAL SCIENCES Chemistry Biochemistry Molecular biology; NATURVETENSKAP Kemi Biokemi Molekylärbiologi; molekylärgenetik; Molecular Genetics;

    Sammanfattning : The use of transformed bacteria to stop or kill disease-causing agents in the gut of vector insects is called paratransgenics. Two of the major steps in creating a paratransgenic Anopheles mosquito, unable to spread the Plasmodium parasites that cause malaria, are to find a bacterium suitable for the purpose and a way to introduce the transformed bacterium into mosquitoes in the field.

  3. 3. Impact of the gut microflora on the digestive system in the suckling rat

    Detta är en avhandling från Department of Cell and Organism Biology, Lund University

    Författare :Frida Fåk; Lunds universitet.; Lund University.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; probiotics; prebiotics; antibiotics; lactobacilli; bacteria; intestinal permeability; Small intestine; maturation; weaning; suckling;

    Sammanfattning : The postnatal development of the gastrointestinal (GI) system in mammals is genetically programmed, but is, to an unknown extent, regulated by external factors such as the diet and the gut microflora. These factors can influence the growth of the GI tract, the age-related pattern of appearance of digestive enzymes and the decreased intestinal macromolecular permeability at gut closure, normally timed with weaning in young rodents.

  4. 4. β-Mannan degradation by gut bacteria - Characterization of β-mannanases from families GH5 and GH26

    Detta är en avhandling från Department of Chemistry, Lund University

    Sammanfattning : Popular Abstract in Swedish Människan lever inte bara själv, utan tillsammans med en mängd bakterier som lever i kroppen. Större delen av dessa lever i tjocktarmen. Dessa organismer är viktiga för vår hälsa. De stimulerar immunförsvaret, sänker pH i tarmen och gör det ogynnsamt för sjukdomsframkallande bakterier att växa till. LÄS MER

  5. 5. Innate immunity of human intestinal epithelium in childhood celiac disease influences from celiac disease associated bacteria and dietary oats

    Detta är en avhandling från Umeå : Umeå University

    Författare :Grzegorz Pietz; Umeå universitet.; [2017]

    Sammanfattning : Background & Aims: Celiac disease (CD) is a chronic inflammatory small-bowel enteropathy caused by permanent intolerance to gliadin in wheat gluten, and related proteins in ray and barley. It is disputed whether CD patients tolerate oats. The only treatment of CD is lifelong gluten-free diet (GFD). LÄS MER
