Active and passive immunization of ducks against duck viral enteritis
Avian Diseases
|October 1, 1984
Abstract:
The newly isolated Sheridan-83 strain of duck enteritis virus (DEV) was apathogenic to ducks. Inoculation of ducks with this virus resulted in the production of antibodies that enabled the ducks to resist challenge with the virulent LA strain of DEV. The minimum protective dose of the Sheridan-83 virus was determined to be less than 10 TCID50. Solid immunity lasted 1-2 months. Passive transfer of antibodies to susceptible ducks also significantly protected them from lethal challenge.
