title: A solitary case of duck plague in a wild mallard.
abstract: Duck plague was diagnosed on the basis of pathology and virus isolation in a wild female mallard Anas platyrhynchos found dead near Saskatoon, Saskatchewan. Day-old Pekin ducklings and one of two adult mallards died with lesions typical of duck plague following inoculation of tissue from the wild bird. This is believed to be the only reported case of duck plague in a wild bird since a major outbreak occurred in South Dakota in 1973, and the fourth such report in North America.
