The present invention provides polynucleotide which encodes an EcR or USP polypeptide of a B. ovis ecdysone receptor. The present invention contemplates the use of such polynucleotides in the generation of transgenic constructs, cells, animals, microorganisms, plants or acquatic organisms. The present invention further contemplates the use of such polynucleotides to confer resistance or immunity to B. ovis and to treat an animal having B. ovis infestation. |
