  1. 21. Parasite virulence and disease severity in Plasmodium falciparum malaria

    Författare :Ulf Ribacke; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Malaria stands out as one of the most important infectious diseases and one of the world s leading causes of death. Plasmodium falciparum is the parasite responsible for the great majority of severe disease syndromes and mortality, and affects mainly children and pregnant women. Despite intensive research efforts, the understanding of P. LÄS MER

  3. 22. A Genetic Survey of the Pathogenic Parasite Trypanosoma cruzi

    Författare :Anh-Nhi Tran; Lena Åslund; John Kelly; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; Trypanosoma cruzi; Chagas ; gene discovery; EST; sequencing; DGC3; repeats; gene family; CL Brener; trypanothione synthetase; TcTRS locus; alleles; polymorphism; RNA-binding protein; TcPTB; stage-specific expression; Genetik; Genetics; Genetik; medicinsk genetik; Medical Genetics;

    Sammanfattning : Trypanosoma cruzi, the causative agent of Chagas´ disease, is an evolutionarily ancient species with distinct biological and immunological characteristics. A fundamental understanding of the basic biology of the parasite is necessary in order to develop reliable therapeutic and prophylactic agents against T. cruzi. We have, as a part of the T. LÄS MER

  4. 23. Studies on malaria blood stage infection and host responses

    Författare :Lili Xu; Klavs Berzins; Adrian Luty; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malaria; cytokines; parasite ligands; merozoite released soluble proteins MRSPs ; molekylär biovetenskap; Molecular Biosciences;

    Sammanfattning : The challenges in controlling malaria infectious disease are increasing due to drug resistance and incomplete immunity induced by malaria infection. Moreover there is no effective vaccine available against malaria blood stage infection. LÄS MER

  5. 24. Comparative Cell Biology in Diplomonads

    Författare :Elin Einarsson; Staffan Svärd; Scott Dawson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Giardia intestinalis; Spironucleus salmonicida; intestinal parasite; hydrogenosome; encystation; gene regulation; transfection; diplomonad; antigenic variation; annexin;

    Sammanfattning : The diplomonads are a diverse group of eukaryotic flagellates found in microaerophilic and anaerobic environments. The most studied diplomonad is the intestinal parasite Giardia intestinalis, which infects a variety of mammals and cause diarrheal disease. LÄS MER

  7. 25. On the Effects of Blood Parasites in Wild Birds

    Författare :Peter Halvarsson; Jacob Höglund; Staffan Bensch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atoxoplasma; avian malaria; coccidia; Gallinago media; Haemoproteus; Leucocytozoon; parasite prevalence; Passer montanus; Plasmodium; recapture mod-els; survival; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Sammanfattning : Coccidian and haemoatozoan parasites are commonly occurring endo-parasites in wild birds and prevalence can vary among species and populations. In addition to prevalence studies, parasites are often used to investigate effects on life history traits. LÄS MER
