The present invention relates to the field of double-stranded RNA (ds RNA) mediated gene silencing of root knot nematodes. The invention particularly provides an effective method for reducing the number of reproducing population and the number of progenies per individual of the root knot nematodes. The present invention also relates to host delivered dsRNA for controlling infection of root knot nematodes.

Disclosed herein are immunogenic compositions for preventing or treating infection with filarial parasites and biomarkers for diagnosing infection with filarial parasites.

The present invention discloses gene targets, constructs and methods for the genetic control of plant disease caused by nematodes of the genus Meloidogyne (root knot nematodes). The present invention relates to achieving a plant protective effect through the identification of target coding sequences and the use of recombinant DNA technologies for post-transcriptionally repressing or inhibiting expression of the target coding sequences in the cells of plant-parasitic nematodes. The disclosed gene targets show significant conservation at the nucleotide level between orthologs from different Meloidogyne species, facilitating genus-wide targeting by RNA interference.

The present invention is a multivalent vaccine for immunizing an animal against filariasis. In some embodiments, the antigens of the multivalent vaccine are protein-based, DNA-based, or a combination thereof. This invention also provides a method and kit for detecting a filarial nematode and determining vaccine efficacy.

The invention relates to identifying and evaluating target coding sequences for control of plant parasitic nematodes by inhibiting one or more biological functions, and their use. The invention provides methods and compositions for identification of such sequences and for the control of a plant-parasitic nematode population. By feeding one or more recombinant double stranded RNA molecules provided by the invention to the nematode, a reduction in disease may be obtained through suppression of nematode gene expression. The invention is also directed to methods for making transgenic plants that express the double stranded RNA molecules, and the plant cells and plants obtained thereby.

The present invention relates to nucleotide sequences encoding Cooperia antigens, as well as to recombinant DNA molecules containing such nucleotide sequences and host cells expressing these nucleotide sequences. The invention further relates to Cooperia proteins, to methods for the production of the proteins, nucleotide sequences, recombinant DNA molecules and hosts. Furthermore, the invention relates to vaccines which induce protective immunity against infection by parasitic nematodes such as species of the genus Cooperia and to methods for preparing such a vaccine.

The present invention relates to vaccines comprising a ShK domain of a filarial nematode protein. These vaccines may be used for die prevention and/or treatment of filarial nematode infections. The invention also relates to novel proteins comprising a ShK domain of a filarial nematode protein and pharmaceutical compositions. The invention may be used for the prevention and/or treatment of filarial nematode infections in canine subjects, and also in human subjects.

Disclosed are methods of detecting the presence of detecting the presence of Loa loa in a biological sample using one or more antigens, each having a different amino acid sequence selected from the group consisting of SEQ ID NOs: 1-20. Related compositions, specific binding partners, and test kits are also disclosed.
