  • Patent number: 7968695
    Abstract: The present invention provides the recombinant cloning and sequencing of two of the major Eimeria maxima gametocyte antigens having molecular weights of 56 and 82 kDa and the expression of these recombinant antigens in an E. coli expression system using the plasmid pTrcHis. The subject invention also provides a vaccine against coccidiosis comprising the recombinant 56 kDa or 82 kDa antigen. The subject invention also provides two 30 kDa proteins and three 14 kDa proteins from Eimeria maxima gametocytes having at the N-terminal end the amino acid sequence described herein. The subject invention also provides a vaccine against coccidiosis comprising the recombinant 56 kDa or 82 kDa antigen and any of the aforementioned proteins.
    Type: Grant

  • Patent number: 7462707
    Abstract: The present invention provides an isolated nucleic acid comprising a nucleotide sequence encoding a 250 kDa polypeptide from Sporozoites/Merozoites of Eimeria maxima, or encoding a homolog of the polypeptide, or a complement of the nucleic acid and a method of producing a recombinant 250 kDa polypeptide of the same. The present invention also provides an isolated nucleic acid comprising a nucleotide sequence encoding an immunodominant portion of a 250 kDa polypeptide from Sporozoites/Merozoites of Eimeria maxima having the amino acid sequence described herein, or encoding a homolog of the polypeptide, or a complement of the nucleic acid.
