PHAGE-GNRH CONSTRUCTS, THEIR MIMICS, ANTIGENIC COMPOSITIONS, AND SEQUENCES FOR IMMUNOCONTRACEPTION OF ANIMALS AND OTHER APPLICATIONS

摘要

Disclosed are recombinant bacteriophage constructs and related heterologous peptide sequences for contraception in animals. The disclosed recombinant phage constructs bind to antibodies against gonadotropin releasing hormone (GnRH) and can be administered to an animal to generate an immune response against GnRH, including generating anti-GnRH antibodies. The disclosed recombinant phage may comprise an amino acid sequence of gonadotropin releasing hormone (GnRH), epitopic fragments, variants, or functional mimics thereof. Also disclosed are methods for making and selecting such recombinant phage constructs and compositions that comprise such constructs (e.g., compositions for inducing an immune response against GnRH including pharmaceutical or veterinary compositions used as vaccines). Also disclosed are recombinant polynucleotides comprising genomic nucleic acid of the recombinant phage constructs disclosed herein.
