  1. 21. Non-invasive Antibody Production in the Chicken

    Författare :Susan L Mayo; Hans-Erik Carlsson; Jann Hau; Torgny Stigbrand; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Laboratory animal science; Försöksdjursvetenskap; försöksdjursvetenskap comparative medicine; försöksdjursvetenskap comparative medicine;

    Sammanfattning : The production of antibodies for analytical purposes using invasive procedures on small mammals is common practice in biomedical research. The aim of this study was to develop an efficient method for non-invasive antibody production in the chicken. LÄS MER

  3. 22. Genetic Studies of Pigmentation in Chicken

    Författare :Ulrika Gunnarsson; Leif Andersson; Göran Andersson; Susanne Kerje; William J. Pavan; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : Domestic animals have been selected by humans for thousands of years, which have drastically altered their genetic constitution and phenotypes. In this thesis, several of the most important genes causing pigmentation differences between the wild red junglefowl (Gallus gallus) and domestic chickens have been identified. LÄS MER

  4. 23. Avian Influenza Virus : Deciphering receptor interactions and their role in interspecies transmission

    Författare :Per Eriksson; Patrik Ellström; Björn Olsen; Josef D. Järhult; Åke Lundkvist; Jonas Waldenström; Hans-Dieter Klenk; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; birds; glycobiology; glycovirology; host range; mixing vessel; virus attachment; Medical Virology; Medicinsk virologi;

    Sammanfattning : Influenza A virus (IAV) annually infects approximately 5–15 % of the human population, causing ~500,000 deaths globally. Novel IAVs have emerged and spread pandemically in the human population, but have over time established endemic circulation with reduced pathogenicity causing seasonal influenza. The natural reservoir of IAVs is wild waterfowl. LÄS MER

  5. 24. Erysipelothrix rhusiopathiae in laying hens

    Författare :Helena Eriksson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The bacterium Erysipelothrix rhusiopathiae can infect a wide range of mammals (including humans) and birds. Disease outbreaks (erysipelas) have been considered unusual in chickens internationally, but outbreaks with high mortality and egg production losses have been diagnosed in Swedish laying hen flocks every year since 1998.

  7. 25. The neurotoxin β-N-methylamino-L-alanine (BMAA) and 2,4-diaminobutyric acid (DAB) : possible risk of human exposure, and the effect and function in diatoms

    Författare :Sea-Yong Kim; Sara Rydberg; Sandra Banack; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; växtfysiologi; Plant Physiology;

    Sammanfattning : The toxic secondary metabolites β-N-methylamino-L-alanine (BMAA) and 2,4-diaminobutyric acid (DAB) produced by phytoplankton groups such as cyanobacteria, diatoms and dinoflagellates are known to cause neurotoxicity in vertebrates. BMAA has been linked to development of the neurodegenerative diseases amyotrophic lateral sclerosis/Parkinsonism dementia complex (ALS/PDC) and Alzheimer's disease. LÄS MER
