Beschreibung
Zusammenfassung:	The present invention provides improved methods and compositions for sporulating oocysts. The sporulated oocysts produced according to the invention find use in the manufacture of vaccines. In preferred embodiments, the present invention provides methods and compositions for the sporulation of Eimeria oocysts. Vaccines containing Eimeria oocysts, sporocysts and/or sporozoites produced according to the present invention may be used to immunize birds against coccidiosis either in ovo or post hatch. La présente invention concerne des procédés et des compositions améliorées pour la production d'ovocytes. Les ovocytes produits selon l'invention présentent une grande utilité pour la fabrication de vaccins. Dans des modes de réalisation préférés, la présente invention traite de procédés et de compositions pour la production d'ovocytes d'Eimeria . Les vaccins contenant des ovocytes d'Eimeria, des sporocystes et/ou des sporozoïtes produits selon l'invention permettent d'immuniser des oiseaux contre la coccidiose dans l'oeuf ou après l'éclosion.
