  1. 1. Bacterial viruses targeting multi-resistant Klebsiella pneumoniae and Escherichia coli

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Harald Eriksson; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacterial viruses; Bacteriophage; Phage; Phage therapy; multi-resistant bacteria; Klebsiella pneumoniae; molekylärgenetik; Molecular Genetics;

    Abstract : The global increase in antibiotic resistance levels in bacteria is a growing concern to our society and highlights the need for alternative strategies to combat bacterial infections. Bacterial viruses (phages) are the natural predators of bacteria and are as diverse as their hosts, but our understanding of them is limited. READ MORE

  2. 2. Exploring the diversity and evolution of giant viruses in deep sea sediments using genome-resolved metagenomics

    University dissertation from Uppsala : Uppsala universitet

    Author : Disa Bäckström; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metagenomics; binning; viruses; NCLDV; Megavirales; viral evolution.;

    Abstract : Viruses are the most abundant biological entities on this planet, which is impressive considering that they are completely dependent on their hosts for reproduction. Recently the idea of what viruses are has changed dramatically, with the discovery of giant viruses that belong to the Nucleocytoplasmic Large DNA Viruses (NCLDV), such as Mimiviridae, Marseilleviridae, and the proposed families Pandoraviruses, and Pithoviruses.
