1. Molecular characterization and detection of infectious bronchitis virus
Sammanfattning : 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.

2. Innate immune responses to a saponin adjuvant in the pig : application of gene expression profiling
Sammanfattning : 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. LÄS MER
3. Evaluation of macrocyclic lactone resistance in gastrointestinal nematodes of first season grazing cattle
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
4. Wild rodents as carriers of potential pathogens to pigs, chickens and humans : with special emphasis on Brachyspira spp. and Yersinia enterocolitica
Sammanfattning : 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. LÄS MER
5. Hygiene aspects of the biogas process with emphasis on spore-forming bacteria
Sammanfattning : Biogas is a renewable source of energy which can be obtained from processing of biowaste. The digested residues can be used as fertiliser. Biowaste intended for biogas production contains pathogenic micro-organisms. A pre-pasteurisation step at 70°C for 60 min before anaerobic digestion reduces non spore-forming bacteria such as Salmonella spp. LÄS MER
