  1. 6. A transcriptomic tale of two worms : Evaluating Caenorhabditis elegans as a model for Parascaris univalens in drug resistance studies

    Författare :Faruk Dube; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Parascaris univalens, an equine roundworm, poses a significant threat to foals, potentially causing lethal intestinal ruptures in high infestations. Infection control relies on a limited arsenal of anthelmintic drugs like ivermectin (IVM). LÄS MER

  3. 7. The control of growth and metabolism in Caenorhabditis elegans

    Författare :Josefin Friberg; Simon Tuck; Cathy Savage-Dunn; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TGFβ; insulin; collagen; p70 S6K; metabolism; growth; dauer; Caenorhabditis elegans; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : The control of growth is a poorly understood aspect of animal development. This thesis focuses on body size regulation in Caenorhabditis elegans, and in particular, how worms grow to a certain size. In C. elegans, a key regulator of size is the TGFβ homologue DBL-1. LÄS MER

  4. 8. Helminths and immunity against tuberculosis

    Författare :Daniel Elias; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :tuberculosis; BCG; helminths; immunomodulation; vaccination;

    Sammanfattning : The efficacy of Bacille Calmette Guerin (BCG) is low and incidence of tuberculosis (TB) is high in those areas where helminths are endemic. Protection against tuberculosis requires strong cell mediated immunity while chronic helminth infections induce responses characterized by dominant Th2 responses as well as up-regulated regulatory T cell activity.

  5. 9. Evaluation of macrocyclic lactone resistance in gastrointestinal nematodes of first season grazing cattle

    Författare :Marlene Areskog; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Parasitic gastrointestinal nematodes (GIN) are common world-wide among grazing cattle, and cause welfare problems and associated economic losses due to reduced performance of their hosts. In Sweden, the most important GIN include Cooperia oncophora and the more pathogenic Ostertagia ostertagi, which are usually present as mixed infections in first season grazing cattle (FSG). LÄS MER

  7. 10. Serodiagnostics of schistosomiasis using keyhole limpet hemocyanin (KLH) as antigen

    Författare :Cecilia Thors; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The diagnostics of invasive helminth infections is often indirect and based on antibody detection in serum specimens from infected individuals. This is the case in schistosomiasis (bilharzia) where no excreted eggs can be found in light, often asymptomatic, infection. LÄS MER
