  1. 31. Structure and function of microbial communities in acid sulfate soil and the terrestrial deep biosphere

    Författare :Xiaofen Wu; Mark Dopson; Ricardo Amils; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular phylogeny; acid sulfate soils; metal; acidophiles; deep biosphere; oligotrophy; biofilm formation; metagenome; binning; metabolism; Mikrobiologi; Microbiology;

    Sammanfattning : This thesis describes the use of different DNA sequencing technologies to investigate the structure and function of microbial communities in two extreme environments, boreal acid sulfate soil and the terrestrial deep biosphere.The first of the two investigated environments was soils containing un-oxidized metal sulfides that are termed ‘potential acid sulfate soil’ (PASS) materials.

  3. 32. Effects of biocides and metals on antibiotic resistance: a genomic and metagenomic perspective

    Författare :Chandan Pal; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance; biocide; metal; co-selection; metagenomics;

    Sammanfattning : Background and aim: There is a concern that biocides and metals can co-select for antibiotic resistance. The aim of this thesis is to enhance our understanding of the roles of antibacterial biocides (e.g. antiseptics, disinfectants) and metals (e. LÄS MER

  4. 33. Birds and Borrelia

    Författare :Björn Olsen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; Ixodes ticks; Birds; Epidemiology; Zoonotisk ekologi; Virology; Mikrobiologi;

    Sammanfattning : The Lyme disease causing spirochaete Borrelia burgdorferi sensu lato is transmitted by ticks within the genus Ixodes. These ticks are liberal host seekers and parasitise mammals, birds and reptiles.Prior to this study, the distribution of I. ricinus ticks and Lyme disease was thought to be restricted to the southern half of Sweden.
