Serologic and Epidemiologic Evidence of Infection in Turkeys with an Agent Related to the Swine Influenza Virus

Abstract

Two outbreaks of influenza were diagnosed in two turkey breeder flocks raised in consecutive years on an Ohio farm that also had a swine operation. The antibody detected indicated that the virus causing the disease had the Hswl hemagglutinin (swine influenza). Signs of disease onset were a decline in egg production and an increase in the number of abnormal eggs. Antibodies against the Hswl hemagglutinin were detected in swine raised on the farm.
