  • Coccidiosis vaccines
    Patent number: 4438097
    Abstract: Attenuated E. necatrix suitable for use in the production of a live vaccine is produced by passaging pathogenic E. necatrix in embryonated eggs for a sufficient number of passages i.e. from about 20 up to about 50 or more egg passages.
