This invention provides DNA sequences coding for Eimeria surface antigens, recombinant vectors containing such DNA sequences, transformed microorganisms containing such vectors, and methods for producing the antigens using the transformed microorganisms. Methods are also provided for protecting poultry against coccidiosis using the Eimeria surface antigens. The surface antigens can be administered for such protection either as purified proteins or in the form of DNA encoding the proteins in a suitable viral vector such as vaccinia virus.

Recombinant coccidiosis vaccines

The present invention relates to recombinant vaccinia viruses which are derived from the modified virus Ankara (MVA) and which contain a DNA sequence which codes for a foreign antigen. The invention also relates to vaccines which contain a virus of this type in a form suitable for injection, as well as to a method for the preparation thereof. Furthermore, the invention relates to the use of a recombinant vaccinia virus MVA for the preparation of heterologous proteins in eukariotic cells.
