  1. 1. Hidden Diversity Revealed Genomic, Transcriptomic and Functional Studies of Diplomonads

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jon Jerlström-Hultqvist; Staffan Svärd; Adrian Hehl; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Giardia intestinalis; Spironucleus salmonicida; Spironucleus barkhanus; intestinal parasite; hydrogenosome; mitosome; lateral gene transfer; horizontal gene transfer; diplomonad; metamonad; sexual recombination; transfection; protein complex purification; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : The diplomonads are a diverse group of eukaryotic microbes found in oxygen limited environments such as the intestine of animals were they may cause severe disease. Among them, the prominent human parasite Giardia intestinalis non-invasivelycolonizes the small intestine of humans and animals where it induces the gastrointestinal disease giardiasis. READ MORE

  2. 2. Comparative Genomics in Diplomonads Lifestyle Variations Revealed at Genetic Level

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Feifei Xu; Jan O. Andersson; Staffan G. Svärd; Matt Berriman; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; comparative genomics; Giardia intestinalis; Spironucleus salmonicida; Trepomonas; diplomonad; intestinal parasite; free-living; sexual recombination; hydrogenosome; horizontal gene transfer; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : As sequencing technologies advance genome studies are becoming a basic tool for studying an organism, and with more genomes available comparative genomics is maturing into a powerful tool for biological research. This thesis demonstrates the strength of a comparative genomics approach on a group of understudied eukaryotes, the diplomonads. READ MORE

  3. 3. Evolution of symbiotic lineages and the origin of new traits

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Daniel Tamarit; Siv G. E. Andersson; Lisa Klasson; Amparo Latorre; Julian Parkhill; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; symbiosis; host-association; Lactobacillus; Bifidobacterium; Rhizobiales; Bartonella; honeybees; ants; codon usage bias; genome architecture; genome organization; gene transfer agent; evolutionary genomics; comparative genomics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : This thesis focuses on the genomic study of symbionts of two different groups of hymenopterans: bees and ants. Both groups of insects have major ecological impact, and investigating their microbiomes increases our understanding of their health, diversity and evolution. READ MORE

  4. 4. Surviving the ratchet Modelling deleterious mutations in asexual populations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Söderberg; Otto Berg; Laurence Loewe; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical biology; Population genetics; Stochastic modelling; Genome evolution; Muller s Ratchet; NATURAL SCIENCES Biology Cell and molecular biology Genetics; NATURVETENSKAP Biologi Cell- och molekylärbiologi Genetik; NATURAL SCIENCES Biology Organism biology; NATURVETENSKAP Biologi Organismbiologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : One of the most unforgiving processes in nature is that of Muller's ratchet, a seemingly irreversible accumulation of deleterious mutations that all organisms have to deal with or face extinction. The most obvious way to avoid fitness collapse is recombination, though asexual populations usually do not have the luxury of recombining freely. READ MORE

  5. 5. Antibiotic Resistance Selection in the Presence of Metals and Antimicrobials

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lisa M. Albrecht; Dan I Andersson; Alex O'Neill; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance; Metals; Antimicrobials; Bacterial evolution; Bacterial genetics; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : The external environment is complex: Antibiotics, metals and antimicrobials do not exist in isolation but in mixtures. Human activities such as animal husbandry, fertilization of agricultural fields and human medicine release high amounts these compounds into the environment. READ MORE
