  2. 1. Pathobiology of avian influenza in wild bird species

    Author : Caroline Bröjer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Avian influenza viruses, especially highly pathogenic avian influenza viruses (HPAIV), affect a wide range of species, including humans and have thus become a major concern for veterinary medicine and public health. A HPAIV-H5N1 belonging to clade 2.2, originally from South East Asia, spread across Eurasia and reached Sweden in 2006. READ MORE

  4. 2. Molecular characterization and detection of infectious bronchitis virus

    Author : hussain Shahid Abro; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis deals with the molecular characterization and detection of infectious bronchitis virus (IBV), an important pathogen that causes heavy losses in the poultry populations worldwide. The aim of the research was to better understand the molecular characteristics of the virus and to investigate the factors behind the continuous emergence of new genetic variants and the occurrence of outbreaks.

  5. 3. Innate immune responses to a saponin adjuvant in the pig : application of gene expression profiling

    Author : Viktor Ahlberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Vaccination is one of the most powerful ways to prevent infectious diseases. Successful vaccines produce a long-term immunity including effector T and B lymphocytes. In this context, adjuvants have a key role in vaccines by stimulating the innate immunity and thereby enhancing and shaping the subsequent adaptive immune response. READ MORE

  6. 4. Evaluation of macrocyclic lactone resistance in gastrointestinal nematodes of first season grazing cattle

    Author : Marlene Areskog; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : 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).

  7. 5. Wild rodents as carriers of potential pathogens to pigs, chickens and humans : with special emphasis on Brachyspira spp. and Yersinia enterocolitica

    Author : Annette Backhans; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The aim of this thesis was to investigate the specific risks that rodents constitute for proliferation of pathogens and transmission of those to farm animals, and indirectly to humans. Rodents were captured in pig and chicken flocks, in wastewater treatment plants and other urban environments. READ MORE
