Pathology of Highly Pathogenic Avian Influenza Virus (H5N1) Infection in Canada Geese (Branta canadensis)
Susceptibility of Canada geese ( Branta canadensis) to highly pathogenic avian influenza (HPAI) virus (H5N1) infection was studied by inoculating 10 naïve (antibody-negative) animals (5 adults and 5 juveniles) with A/chicken/Vietnam/14/05 (H5N1) virus. In the adults, 1 of 5 became infected, and 4 of...
