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.

Polynucleotides encoding excretory/secretory proteins of parasitic

Disclosed is a substantially purified antigen derived from a first species of parasitic nematodes, which antigen is capable of providing protection to a host from parasitism infestation by a second nematode species, which may be the same as or different from the first nematode species, following vaccination of the host with the antigen, characterized in that the antigen is proteinaceous, has a pI between 3.8 and 4.4, can be bound by lentil lectin and Helix promatia and has a molecular weight of approximately 45 kD as determined by SDS-PAGE.

Nematode vaccine

The invention disclosed relates to proteins derived from parasitic nematodes that confer protective immunity against infection by parasitic nematodes, to nucleotide sequences encoding those 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.

Vaccines against animal parasitic nematodes

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.

Disclosed is a substantially purified antigen derived from a first parasitic nematode species which, when administered to a host animal, is capable of protecting the host animal from infestation by a second parasitic mematode species, wherein the first and second parasitic nematode species may be the same or different, and the antigen has an apparent molecular weight of 40 kD as determined by SDS-PAGE under reducing conditions.
