  1. 1. Diversity of avian haemosporidian parasites : Host specificity, genetic structure and infection patterns

    Författare :Xi Huang; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Haemoproteus; Sequence capture; host specificity; quantitative PCR; phylogeny;

    Sammanfattning : Parasites live on or inside their hosts and usually cause fitness loss, sometimes even lead to outbreaks of emerging infectious disease. Understanding how a parasite can infect its hosts (i.e., host specificity of the parasite) is important to both basic studies on disease evolution and the whole ecosystem health. LÄS MER

  3. 2. Avian Malaria and Related Blood Parasites: Molecular Diversity, Ecology and Evolution

    Författare :Olof Hellgren; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diversity; Plasmodium; bird-migration; transmission; blackfly; host-specificity; host-preference; cytochrome b; DHFR-TS; recombination; phylogeny; Ecology; Ekologi; Genetics; cytogenetics; Genetik; cytogenetik; Parasitology human and animal ; Haemoproteus; Leucocytozoon; Parasitologi människa och djur ; Animal ecology; Djurekologi; Natural science; Naturvetenskap;

    Sammanfattning : Malaria-like parasites consist of a large group of species that infects primates, rodents, bats, lizard and birds. I have focused on parasites from the genera Haemoproteus, Plasmodium and Leucocytozoon that are infecting birds. LÄS MER

  4. 3. Contributions to the understanding of diversity and evolution in the genus Coreomyces

    Författare :Henrik Sundberg; Stefan Ekman; Åsa Kruys; Donald H. Pfister; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ascomycetes; Coreomyces; Corixidae. DNA; DNA extraction; Fungi; ge-nome; host specificity; Laboulbeniales; mating types; MAT-loci; meth-odology; NGS; parasite; position specificity; systematics; taxonomy; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

    Sammanfattning : The Laboulbeniales is an order of enigmatic ascomycete fungi that are obligate microscopic parasites of arthropods, which are usually non-detrimental. They typically display a high degree of host specificity, and the genus Coreomyces, which is the recurring theme of this thesis, is no exception. LÄS MER

  5. 4. Cleavage Specificity of Mast Cell Chymases

    Författare :Mattias K. Andersson; Lars Hellman; Gunnar Pejler; Per Venge; Uppsala universitet; []
    Nyckelord :Biology; Immunology; Mast cell; Serine protease; Chymase; Cleavage specificity; Phage display; Biologi;

    Sammanfattning : Mast cells (MC) are potent inflammatory cells that are known primarily for their prominent role in IgE mediated allergies. However, they also provide beneficial functions to the host, e.g. in bacterial and parasitic defence. LÄS MER

  7. 5. Understanding Complex Diseases and Disease Causative Agents : The Machine Learning way

    Författare :Zeeshan Khaliq; Jan Komorowski; Steven Bosinger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pathogens; Influenza A viruses; Human immunodeficiency virus; Simian immunodeficiency virus; Pathogenicity; Cancer; long noncoding RNAs; Machine learning; Host specificity; Host-specific signatures; Bioinformatics; Bioinformatik;

    Sammanfattning : Diseases can be caused by foreign agents – pathogens – such as viruses, bacteria and other parasites, entering the body or by an internal malfunction of the body itself. The partial understanding of diseases like cancer and the ones caused by viruses, like the influenza A viruses (IAVs) and the human immunodeficiency virus, means we still do not have an efficient cure or defence against them.
