PROTEINS, AND THEIR USE

摘要

The present invention is directed to providing a vaccine to enhance the immune response of an animal in need of protection against a Group B Streptococcus (GBS) infection. The present invention is also directed toward a composition comprising two or more of polypeptides, wherein said polypeptide comprises an amino acid sequence at least 80% identical to the reference amino acid sequence selected from the group consisting of Pho1-13, Pho1-14, Pho1-5, Pho3-3 (pho1-7), Pho2-10, Pho2-15, Pho2-2 (ME:P22), Pho3-14, Pho3-17, Pho3-18, Pho3-1 (ME:P31), Pho3-21, Pho3-22, Pho3-23, Pho3-24, Pho3- 29, Pho3-50, MS4, MS11, MS16, MS14, MS10(NP GAP, ME:NAP), PBP, pho 3-9, OCT, PGK, and NPGAP, a fragment, variant, analog, or derivative thereof, wherein said polypeptide is recognizable by an antibody preparation that specifically binds to a polypeptide consisting of the reference amino acid sequence. In some embodiments, the present invention is directed to a method of inducing an immune response in a host comprising administering to said host an effective amount of the composition of the present invention.
