Viral shedding and antibody response of mallard ducks to avian influenza viruses
MetadataShow full item record
Wild ducks are a key reservoir for avian influenza (AI) viruses. Their long distance migrations, coupled to frequent contact with domestic poultry enhances risk for spread of highly pathogenic avian influenza (HPAI) viruses. Despite years of study, our understanding of how AI viruses are maintained and transmitted in nature remains poorly understood. The work described here examines several aspects of avian influenza virus infections that play a role in perpetuation and spread of this disease, including persistence of virus in duck feces, effect of prior exposure to AI viruses on subsequent ...
