Abstract:
Pekin ducklings were vaccinated with Freund's complete adjuvant plus free Plasmodium lophurae parasites, erythrocytes infected with P. lophurae schizonts, or parasite membrane vesicles. Approximately 50% of the vaccinated ducklings were resistant to challenge with this malarial parasite. However, little protection was afforded by immunization of ducklings with a parasite-specific histidine-rich protein.
