  3. 7. Evolution and host-specific adaptations of Legionella pneumophila

    Författare :Anaísa B. Moreno; Lionel Guy; Dan I. Andersson; Fredrik Söderbom; Alexander W. Ensminger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolution; Legionella pneumophila; host-adaptation; experimental evolution; Acanthamoeba castellanii; transfection; Mikrobiologi; Microbiology;

    Sammanfattning : How bacteria evolve pathogenic traits is shaped by their communities and environments. Legionella pneumophila is ubiquitous in aquatic habitats, where it persists by replicating within a broad range of protozoan hosts. Using the same mechanisms, L. LÄS MER

  4. 8. Plant-seed predator interactions – ecological and evolutionary aspects

    Författare :Hannah Östergård; Johan Ehrlén; Peter Hambäck; William Kunin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; apparent competition; community context; fruit abortion; defence; host range; monophagous; offence; oligophagous; plant-animal interactions; pre-dispersal seed predation; selection; spatio-temporal variation; Biology; Biologi; Plant Ecology; växtekologi;

    Sammanfattning : Plant-animal interactions are affected by both abundance and distribution of interacting species and the community context in which they occur. However, the relative importance of these factors is poorly known. LÄS MER

  5. 9. Avian Malaria and Related Blood Parasites: Molecular Diversity, Ecology and Evolution

    Författare :Olof Hellgren; MEMEG; []

    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

  7. 10. Avian Influenza Virus : Deciphering receptor interactions and their role in interspecies transmission

    Författare :Per Eriksson; Patrik Ellström; Björn Olsen; Josef D. Järhult; Åke Lundkvist; Jonas Waldenström; Hans-Dieter Klenk; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; birds; glycobiology; glycovirology; host range; mixing vessel; virus attachment; Medical Virology; Medicinsk virologi;

    Sammanfattning : Influenza A virus (IAV) annually infects approximately 5–15 % of the human population, causing ~500,000 deaths globally. Novel IAVs have emerged and spread pandemically in the human population, but have over time established endemic circulation with reduced pathogenicity causing seasonal influenza. The natural reservoir of IAVs is wild waterfowl. LÄS MER
