  1. 11. Structural and Functional Studies of Chagasin, a Parasite Protease Inhibitor

    Författare :Anna Ljunggren; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The cysteine proteases are enzymes found in every kingdom of life. Clan CA is the largest of the cysteine protease clans, with members all displaying a Cys/His/Asn(Asp) catalytic triad responsible for hydrolysing the peptide bond within the substrate. LÄS MER

  3. 12. Bioinformatic methods for metagenomics and comparative genetics in veterinary medicine

    Författare :Martin Norling; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Good science includes innovation, investigation, and rigor. This thesis’ first study is related to rigor. This study was performed at the International Livestock Research Institute (ILRI) in Nairobi, as part of the Arbovirus Incidence and Diversity (AVID) project. LÄS MER

  4. 13. Gene Regulation and Epigenetic Mechanisms in the Parasite Trypanosoma cruzi

    Författare :Patricia Respuela; Lena Åslund; George A.M. Cross; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Molecular Biology; Molekylärbiologi;

    Sammanfattning : Trypanosomes are unicellular protozoan parasites responsible for several human diseases that affect millions of people and cause thousands of casualties every year. They also represent a primitive eukaryotic model system harboring unique processes and basic regulatory mechanisms such as RNA-editing, polycistronic transcription and trans-splicing, first described in these organisms.

  5. 14. Bacteria that escape predation : waterborne pathogens and their relatives

    Författare :Karolina I. A. Eriksson; Agneta Andersson; Johanna Thelaus; Jon Ahlinder; David Sundell; Klaus Jürgens; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacterial pathogens; protozoa; predation resistance; aquatic microbiology; climate change; opportunists; humification; iron; environmental science; miljövetenskap; mikrobiologi; Microbiology;

    Sammanfattning : The hidden presence of opportunistic bacterial pathogens in the environment evokes concerns about emerging diseases, especially in the light of climate change. The co-evolution of bacteria and their predators (protozoa) has led to bacterial defence strategies of which some contribute to the ability of bacteria to cause disease. LÄS MER

  7. 15. Toxoplasma gondii in wild boars and domestic pigs in Sweden : implications for food safety

    Författare :Camilla Gustafsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Ingestion of undercooked meat is a major risk factor for human toxoplasmosis, a disease caused by the zoonotic protozoan parasite Toxoplasma gondii. Infected pork, mutton and game meat are considered important infection sources in Europe. This thesis aims to describe the epidemiology of T. LÄS MER
