    Sammanfattning : Background and Aim The aim was to investigate the effects of four early life factors – delivery mode, feeding method, probiotics, and antibiotics – on disease development in childhood. This was done by conducting a structured literature review. LÄS MER

  3. 2. Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics

    Kandidat-uppsats, SLU/Dept. of Microbiology

    Författare :Tua Lilja; [2013]
    Nyckelord :antibiotics; natural products; marine microorganisms; isolation methods; actinomycetes; rare actinomycetes; whole-cell screening; antimicrobials; antibiotic resistance;

    Sammanfattning : The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens.

  4. 3. Selektion av resistenta Escherichia coli vid låga antibiotikakoncentrationer i en gräsandsmodell

    Master-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Marie Nykvist; [2013]
    Nyckelord :antibiotikaresistens; ciprofloxacin; Escherichia coli; gräsand;

    Sammanfattning : Enligt en erkänd hypotes, mutant selection window hypothesis, uppstår och upprätthålls antibiotikaresistens hos bakterier endast då antibiotikakoncentrationerna ligger över minimum inhibitory concentration (MIC)-värdet för en känslig, omuterad population. Det här skulle innebära att de låga antibiotikakoncentrationer man finner i miljön inte borde bidra till att upprätthålla resistens. LÄS MER

  5. 4. Kronisk gastroenterit hos hund med avseende på histopatologisk bild och förekomst av Helicobacter spp

    L3-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Elin Lindell; [2007]
    Nyckelord :helicobacter; gastrit; kräkningar; gastroenterit; bakterier;

    Sammanfattning : It is well known that dogs often have Helicobacter spp in their stomach. The importance of these bacteria in the development of gastrointestinal disease in dogs is still unknown. In humans, Helicobacter pylori is a causative agent of chronic gastritis and gastric ulcers. In contrast to humans, dogs seldom harbour naturally acquired H. LÄS MER
