  3. 2. Quantitative detection of bacterial DNA in whole blood in bloodstream infection

    Författare :Ingrid Ziegler; Kristoffer Strålin; Paula Mölling; Magnus Rasmussen; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bloodstream infection; bacteremia; sepsis; DNA load; quantitative PCR; droplet digital PCR; 16S rDNA;

    Sammanfattning : This thesis aims to increase the knowledge on how quantitative PCR can be used in the diagnostics of bloodstream infections, with an emphasis on quantitative elements.In Papers I and II, we evaluated quantitative data from two commercial PCR tests for pathogen detection directly in blood, Magicplex Sepsis (I) and SeptiFast (II), from patients with suspected sepsis.

  4. 3. Temporal and spatial variation in the community composition of lake bacterioplankton

    Författare :Eva S. Lindström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; bacterioplankton; freshwaters; 16S rDNA; DGGE; community composition; Biologi; Biology; Biologi; limnologi; Limnology;

    Sammanfattning : Bacterioplankton are among the smallest and most abundant organisms in lake ecosystems. Due to the lack of relevant methods, the taxonomic composition of bacterioplankton has been studied less thoroughly than that of larger organisms. LÄS MER

  5. 4. Picophytoplankton seasonal dynamics in the Baltic Sea

    Författare :Javier Alegria Zufía; Hanna Farnelid; Catherine Legrand; Nathan Ahlgren; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; picophytoplankton; Synechococcus; picoeukaryote; phycoerythrin; phycocyanin; ammonium; nitrate; 16S rDNA; flow cytometry; grazing; viral lysis; seasonality; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : Picophytoplankton (15°C there was a preference for ammonium over nitrate. Clade A/B dominated the SYN community, except during summer at the coastal station when low nitrate and warm temperatures promoted S5.2 dominance. Grazing was observed to control SYN and PPE abundances and had an effect on the SYN community structure. LÄS MER

  7. 5. Anaerobic Digestion – Microbial Ecology, Improved Operational Design and Process Monitoring

    Författare :Marika Murto; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monitoring; UASB; Biotechnology; Bioteknik; methanogens; fluorescence in situ hybridisation; FISH; co-digestion; biogas; biofilm; aqueous two phase system; anaerobic digestion; 16S rDNA; alkalinity;

    Sammanfattning : The implementation of anaerobic digestion is important in the concept of sustainable development, especially regarding the environmental benefits. Biogas is produced when organic matter is degraded by microorganisms under oxygen-free (anaerobic) conditions. LÄS MER
