  2. 1. Comparative Genomics of Obligate and Facultative Intracellular Parasites

    Author : Cecilia Alsmark; Russell Regnery; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The α-proteobacteria Rickettsia prowazekii and Bartonella henselae are the causative agents of epidemic typhus and cat scratch disease respectively. Whereas R. prowazekii is an obligate intracellular parasite, B. henselae can live and proliferate both outside and inside the eukaryotic host cell. READ MORE

  4. 2. Lifestyle and Genome Evolution in Vector-Borne Bacteria : A Comparison of Three Bartonella Species

    Author : Anna Carolin Frank; Siv Andersson; Stewart Cole; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Bartonella; evolution; host-restriction; vector-borne; horizontal gene transfer; genome reduction; alpha-proteobacteria; Type-IV secretion; Biologi; Biology; Biologi;

    Abstract : Bacterial genomes provide records of the molecular processes associated with emergence and evolution of different bacterial lifestyles. This thesis is based on whole-genome comparisons within the genus Bartonella, an excellent model system for studies of host- and vector-specificity and infection outcome in animal-associated bacteria.

  5. 3. Studies of Genome Diversity in Bartonella Populations : A journey through cats, mice, men and lice

    Author : Hillevi Lina Lindroos; Siv G. E. Andersson; Richard Birtles; Uppsala universitet; []
    Keywords : Biology; Bartonella; genome content; genome rearrangement; gene expression; phage; microarray; PFGE; MLST; Biologi;

    Abstract : Bacteria of the genus Bartonella inhabit the red blood cells of many mammals, including humans, and are transmitted by blood-sucking arthropod vectors. Different species of Bartonella are associated with different mammalian host species, to which they have adapted and normally do not cause any symptoms. READ MORE

  6. 4. Sudden Cardiac death in Swedish orienteers

    Author : Lars Wesslén; Uppsala universitet; []
    Keywords : Medical sciences; sudden cardiac death; orienteers; myocarditis; arrhythmogenic right ventricular cardiomyopathy; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; infektionssjukdomar; Infectious Diseases;

    Abstract : An accumulation of sudden unexpected cardiac deaths (SUCD) occurred in young Swedish orienteers, most of whom were elite athletes. From 1979 to 1992 the incidence in 18 to 34 year old male elite orienteers ranked on the national level the same year as death was calculated to 30 (per 100,000), which represents a 20 to 40 fold increase from the expected rate.

  7. 5. Mitochondrial Evolution : Turning Bugs into Features

    Author : Olof Karlberg; Siv Andersson; Michael Gray; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Biology; Biologi;

    Abstract : The bacterial origin of mitochondria from an ancient endosymbiosis is now widely accepted and the mitochondrial ancestor is generally believed to belong to the bacterial subdivision α-proteobacteria. The high fraction of mitochondrial proteins encoded in the nucleus has commonly been explained with a massive transfer of genes from the genome of the ancestral mitochondrion. READ MORE
