  1. 1. Production of polyclonal antibodies in rabbits and chickens immunised with human immunoglobulin G : A study of the utility of egg yolk antibody production as a substitute for rabbit serum antibody production

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lise Svendsen Bollen; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Laboratory animals; antibody production; egg yolk; adjuvants; antibody response; avidity; Försöksdjursvetenskap; MEDICINE Physiology and pharmacology Physiology Laboratory animal science; MEDICIN Fysiologi och farmakologi Fysiologi Försöksdjursvetenskap; zoologisk utvecklingsbiologi; Animal Development;

    Sammanfattning : The utility of chicken egg yolk antibodies as an alternative to rabbit antisera was studied by comparing antibody and avidity development in immunised animals (15 rabbits and 30 chickens) during a one-year immunisation scheme. Human IgG was used as the model antigen and the efficacy of three adjuvants, Freund's Complete Adjuvant, Freund's Incomplete Adjuvant and Hunter's TiterMax, was compared. LÄS MER

  2. 2. Avian IgY antibody In vitro and in vivo

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :David Carlander; Lennart Hammarström; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; Antigen production; chicken; cystic fibrosis; egg; ELISA; IgY; immunotherapy; Pseudomonas aeruginosa; yolk; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Sammanfattning : Immunoglobulin Y (IgY) is the major antibody found in eggs from chicken (Gallus domesticus). IgY can be used as an alternative to mammalian antibodies normally used in research, and its use in immunotherapy has recently been proposed. LÄS MER

  3. 3. Domestication effects on foraging behaviour consequences for adaptability in chickens

    Detta är en avhandling från Institutionen för fysik, kemi och biologi

    Författare :Christina Lindqvist; Per Jensen; Björn Forkman; [2008]
    Nyckelord :HUMANIORA; HUMANITIES; Etologi; chicken; domestication effects; behaviour; red jungle fowl RJF ; contrafreeloading CFL ; egg production; HUMANITIES and RELIGION History and philosophy subjects Ethnology; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Etnologi;

    Sammanfattning : The main aim of this thesis was to study domestication effects on foraging behaviour in chickens and to investigate whether and how domestication and selection for high production have influenced adaptability in chickens. Two domestic strains of chickens (egg layers and meat type chickens) and their wild ancestor, the red jungle fowl (RJF) were compared in different test situations with respect to foraging behaviour and adaptability.

  4. 4. Mapping Genes Affecting Phenotypic Traits in Chicken

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Susanne Kerje; Leif Andersson; Martien Groenen; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; chicken; Quantitative Trait Loci; growth; egg production; epistasis; plumage colour; Extended black; MC1R; Dominant white; PMEL17; Genetik; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik;

    Sammanfattning : The purpose of gene mapping is to understand the underlying genetics of simple and complex traits like plumage colour and growth. This thesis is based on a cross between the wild ancestor of the modern chicken, the red junglefowl, and a White Leghorn line selected for high egg mass. LÄS MER

  5. 5. Non-indigenous zooplankton the role of predatory cladocerans and of copepods in trophic dynamics

    Detta är en avhandling från Stockholm : Systemekologiska institutionen

    Författare :Marc Andersen Borg; Fredrik Wulff; Markku Viitasalo; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acartia tonsa; Bythotrephes longimanus; Cercopagis pengoi; egg production; fitness; food web changes; ingestion rates; invasive species; metabolic balance; mortality; non-indigenous zooplankton; predation impact; salinity tolerance; stable isotopes; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi Marin ekologi; marin ekologi; Marine Ecology;

    Sammanfattning : Human-mediated introductions of non-indigenous species now threaten to homogenize the biota of the Globe, causing huge economic and ecological damage. This thesis studies the ecological role of 3 invasive planktonic crustaceans, the omnivorous copepod Acartia tonsa (western Atlantic and Indo-Pacific) and the predatory cladocerans, Cercopagispengoi (Ponto-Caspian) and Bythotrephes longimanus (Eurasian).
