21. Influenza A virus in natural and artificial environments
Sammanfattning : Influenza is caused by influenza A virus, a single stranded RNA virus of the orthomyxoviridae family. In humans, it causes yearly outbreaks with high morbidity and excess fatality rates as a direct effect. Placed in its ecological niche however, in dabbling ducks, avian influenza virus (AIV) induce quite mild disease. LÄS MER
22. Swine influenza A virus subtype H1N2 in Sweden
Sammanfattning : The influenza A virus subtypes H1N1, H1N2 and H3N2 are prevalent in pig populations worldwide. All scientific data point towards swine as the key host species when new human influenza pandemics arise. All previous pandemics have been suggested to evolve in pigs from viral genes of avian, human and porcine origin. LÄS MER

24. Rift Valley fever : consequences of virus-host interactions
Sammanfattning : Rift Valley fever virus (RVFV) is a mosquito-borne virus which has the ability to infect a large variety of animals including humans in Africa and Arabian Peninsula. The abortion rate among these animals are close to 100%, and young animals develop severe disease which often are lethal. LÄS MER
25. Assembly of semliki forest and influenza A viruses
Sammanfattning : Enveloped viruses contain an external lipid membrane with spikes surrounding their nucleocapsid (NC). The envelope is acquired at a late stage of virus assembly by budding of the NC through a virus-modified host membrane. LÄS MER
