  2. 1. Picophytoplankton seasonal dynamics in the Baltic Sea

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

    Abstract : 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. READ MORE

  4. 2. Physics of Viral Infectivity: Energetics of Genome Ejection

    Author : Meerim Jeembaeva; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microfluidics.; differential scanning calorimetry; capsid; Key words: phage; osmotic suppression; DNA ejection; isothermal titration calorimetry; enthalpy;

    Abstract : All viruses that infect bacteria, plant, or animal cells involve a genome (RNA or DNA) that is encapsidated by a rigid protein shell. After delivery of the viral genome into the host cell, new capsid proteins, which are encoded by viral DNA or RNA, are expressed and self-assembled into new viral capsids. READ MORE

  5. 3. Viral Loop Dynamics in Temperate and Polar Freshwaters

    Author : Christin Säwström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; akvatisk ekologi; aquatic ecology; marine biology; Hydrobiology; temperate; polar; freshwaters; nutrient limitation; bacterial mortality; lysogeny; dissolved organic carbon; humic; Arctic; Antarctic; Bacteria; Virus; limnology; Marinbiologi; limnologi;

    Abstract : All cellular organisms in aquatic environments are susceptible to virus attack. Viruses are the smallest but most abundant biological entities in freshwaters. This thesis describes interactions between viruses and bacteria in temperate and polar freshwaters with particular emphasis on Arctic and Antarctic aquatic systems. READ MORE

  6. 4. Significance and Diversity of Lake Bacteriophages

    Author : David Lymer; Eva Lindström; Lars Tranvik; Ruth-Anne Sandaa; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; viral ecology; lake; bacteriophage; diversity; phosphorus; Freshwater ecology; Limnisk ekologi;

    Abstract : Viruses has a relatively recently been discovered in high abundances in aquatic systems. Their possible importance has therefore been largely overlooked. READ MORE

  7. 5. NK cell recognition of herpesviruses : mechanisms of viral immune escape

    Author : Alexander Rölle; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Herpesviruses are ubiquitous pathogens which after an often asymptomatic infection establish lifelong latency in the host. Control of the viral infection depends on both innate and adaptive immune system. READ MORE
