A NOVEL POLYPEPTIDE AND ITS DERIVATIVES, HOMOLOGUES AND ANALOGUES

摘要

The present invention relates generally to a novel polypeptide and its derivatives, homologues, and analogues which polypeptide is obtainable from a helminth, and more particularly a nematode, or produced by recombinant or chemically synthetic means. The polypeptide and its derivatives, homologues and analogues of the present invention may be used in the manufacture of a composition which is capable of inducing protection in helminth-susceptible animals to infection by said helminth and/or to reduce, inhibit or otherwise retard growth, viability and/or egg fecundity of said helminth and/or to ameliorate the symptoms of helminth infection. Another aspect of the present invention contemplates a method of controlling helminth, and more particularly nematode, infection, growth, viability and/or egg fecundity and/or ameliorating the symptoms of helminth infection by the administration of a polypeptide from said helminth or a derivative, homologue, or analogue of said polypeptide.
