Patent ID: 6887686

Claim:
An isolated nucleic acid molecule comprising a coding sequence for an immunogenic H. somnus transferrin-binding protein selected from the group consisting of (a) an immunogenic H. somnus transferrin-binding protein having at least 90% sequence identity to the contiguous sequence of amino acids shown at amino acid positions 1-971, inclusive, of FIG. 3 (SEQ ID NO:2); (b) an immunogenic H. somnus transferrin-binding protein having at least 90% sequence identity to the contiguous sequence of amino acids shown at amino acid positions 29-971, inclusive, of FIG. 3 (SEQ ID NO:2), (c) an immunogenic H. somnus transferrin-binding protein having at least 90% sequence identity to the contiguous sequence of amino acids shown at amino acid positions 1-662, inclusive, of FIG. 4 (SEQ ID NO:3), and (d) an immunogenic H. somnus transferrin-binding protein having at least 90% sequence identity to the contiguous sequence of amino acids shown at amino acid positions 20-662, inclusive, of FIG. 4 (SEQ ID NO:3).
