  1. 1. Host-parasite interactions in space and time

    Författare :Franziska Hildebrandt; Johan Ankarklev; Volker T. Heussler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Malaria; liver-stage infection; Toxoplasma; host-parasite interactions; spatial transcriptomics; single-cell omics; single-cell Dual-seq; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Unicellular parasites of the apicomplexan phylum have a considerable effect on global health and agriculture. Two prominent examples of this phylum include malaria causing parasites of the Plasmodium genus and the widely prevalent parasite Toxoplasma gondii. LÄS MER

  3. 2. Host-Parasite Interactions in Natural Populations

    Författare :Peter Halvarsson; Jacob Höglund; Carles Vilà; Stuart Piertney; Zooekologi Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arvicola terrestris; avian malaria; balancing selection; Major histocompatibility complex; parasitetranscriptome; Populationsbiologi; Population Biology;

    Sammanfattning : Parasitism is one of the most common ways of living and it has arised in many taxa. Parasites feed and live inside or on their hosts resulting in both long and short term consequences for the host. This thesis is exploring the phenotypic and genotypic effects of animals living with parasitic infections. LÄS MER

  4. 3. Host-parasite interactions in the dissemination of Toxoplasma gondii

    Författare :Sachie Kanatani; Antonio Barragan; Per Uhlén; Isabelle Tardieux; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Apicomplexa; dendritic cells; microglia; cell migration; 14-3-3 proteins; GABAergic signaling; voltage-dependent calcium channel; host-parasite interaction; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Toxoplasma gondii is an obligate intracellular parasite that infects virtually all warm-blooded organisms. Systemic dissemination of T. gondii in the organism can cause life-threatening infection that manifests as Toxoplasma encephalitis in immune-compromised patients. LÄS MER

  5. 4. Bird-parasite interactions : Using Sindbis virus as a model system

    Författare :Karin M. Lindström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Carduelis chloris; Sindbis virus; host-parasite interaction; ornament; social dominance; testosterone; sexual selection; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; populationsbiologi; Population Biology;

    Sammanfattning : This thesis focuses on the evolutionary interactions between birds and a parasite, the mosquito-borne Sindbis virus (Togaviridae, Alphavirus). In conclusion, the results show that the Sindbis virus is widespread among birds, and that the fitness of infected hosts may be reduced by the virus. LÄS MER

  7. 5. Host-parasite adaptations and interactions between honey bees, Varroa mites and viruses

    Författare :Barbara Locke Grandér; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The ectoparasitic mite, Varroa destructor, has become the largest threat to apiculture and honey bee health world-wide. Since it was introduced to the new host species, the European honey bee (Apis mellifera), it has been responsible for the near complete eradication of wild and feral honey bee populations in Europe and North America.
