Patent ID: 7335754

Claim:
An isolated recombinant DNA comprising a DNA selected from the group consisting of a) a recombinant DNA that encodes a protein having the amino acid sequence as shown in SEQ. ID. NO. 3 wherein the protein elicits an immune response against E. canis; b) a recombinant DNA that encodes a protein having the amino acid sequence as shown in SEQ. ID. NO. 5 wherein the protein elicits an immune response against E. canis; c) a recombinant DNA that encodes a protein having the amino acid sequence as shown in SEQ. ID. NO. 7 wherein the protein elicits an immune response against E. canis; d) a recombinant DNA that encodes a protein having the amino acid sequence as shown in SEQ. ID. NO. 9 wherein the protein elicits an immune response against E. canis ; and e) a recombinant DNA that encodes a protein having the amino acid sequence as shown in SEQ. ID. NO. 11 wherein the protein elicits an immune response against E. canis.
