A purified antigenic protein has been obtained which is capable of inducing in a chicken an immune response confering protection against infection by Eimeria tenella or Eimeria necatrix. The protein has a molecular weight of about 25,000 and is composed of two polypeptides joined by a disulfide bond. The two polypeptide subunits have molecular weights of about 17,000 and about 8,000 respectively. The, gene encoding the protein has been sequenced and the amino acid sequence of the protein deduced therefrom and by direct peptide sequencing. The protein and antigenic polypeptides having an amino acid sequence included within the protein may be incorporated into a vaccine for conferring upon a …
