Abstract: The invention provides excretory/secretory antigens derived from parasitic nematode species which are capable of inducing protective immunity against infection by parasitic nematode species, and related antigenic molecules. The invention also provides nucleotide sequences encoding the antigens and related molecules of the invention, recombinant DNA molecules comprising the nucleotide sequences, and transformed hosts carrying the recombinant DNA molecules. The invention further provides antibodies against the antigens and related molecules, and antibody compositions comprising the antibodies, vaccines comprising the antigens and/or related molecules and methods of treating or preventing nematode infections using the antigens and related molecules, vaccines, antibodies and/or antibody compositions of the invention.

Abstract: Disclosed is the invention relates to proteins derived from parasitic nematodes which confer protective immunity against infection by parasitic nematodes, to nucleotide sequences encoding these proteins, to recombinant molecules containing such sequences to host cells transformed with such recombinant molecules and methods for the production of the nucleotide sequences recombinant molecules and hosts. The invention also relates to vaccines comprising proteins of the invention together with suitable carriers or diluents and to antibodies raised against proteins of the invention.
