Flea Control by Immunological Intervention. Fleas are bloodsucking parasites that are the major cause of skin disease in pets. Currently, all available flea products rely upon chemical control and many have active components that have real or perceived health problems. Given that insect growth regulators do not kill adult fleas and pet owners are interested in using alternatives to insecticides, there is a clear need for a complementary form of flea control. We describe the novel use of Prote ....Flea Control by Immunological Intervention. Fleas are bloodsucking parasites that are the major cause of skin disease in pets. Currently, all available flea products rely upon chemical control and many have active components that have real or perceived health problems. Given that insect growth regulators do not kill adult fleas and pet owners are interested in using alternatives to insecticides, there is a clear need for a complementary form of flea control. We describe the novel use of Proteomic technology to identify flea proteins that are "switched on" during feeding and are specifically located in the gut. This project will enable the development of a vaccine that is systemic, kills adult fleas, is long-lasting and residue-free.Read moreRead less

Fungal Glucanase Genes for Engineering Disease Resistance in Plants. Plants can be engineered for resistance to fungal diseases by transformation with recombinant genes encoding chitinase or glucanase. Although fungi are prolific producers of glucanases, with some species producing novel forms, they have been unexplored as a source of useful glucanases. This project will isolate glucanase-producing fungi from soil, screen them for antifungal activity, and clone the glucanase genes from one or m ....Fungal Glucanase Genes for Engineering Disease Resistance in Plants. Plants can be engineered for resistance to fungal diseases by transformation with recombinant genes encoding chitinase or glucanase. Although fungi are prolific producers of glucanases, with some species producing novel forms, they have been unexplored as a source of useful glucanases. This project will isolate glucanase-producing fungi from soil, screen them for antifungal activity, and clone the glucanase genes from one or more isolates. In view of the high degree of biodiversity in WA soils, we have a high expectation of finding novel glucanases which will be useful for engineering disease resistance in plants, or for other industrial processes.Read moreRead less

Swine dysentery is a colonic infection of pigs caused by Brachyspira hyodysenteriae. The disease is widespread in Australia and causes great economic loss. An effective vaccine is not available. This study aims to identify factors associated with the bacterium's virulence, using comparative genomic and proteomic information. Virulence factors then will be targeted and tested as recombinant vaccine candidates. This project will result in the development of an improved vaccine to control swine dysentery in rural Australia. Control of swine dysentery through vaccination will reduce antibiotic use on infected farms and improve the productivity and competitiveness of the Australian pig industry.Read moreRead less
Defining the evolutionary processes of resistance to the new mode of action herbicide, pyroxasulfone. The sustainability of the Australin grains industry is threatened by the continuing evolution and widespread expansion of herbicide resistant weed populations across the crop production regions.

The sustainability of the Australin grains industry is threatened by the continuing evolution and widespread expansion of herbicide resistant weed populations across the crop production regions. The resulting loss in herbicide efficacy is forcing producers away from the environmentally friendly practices of stubble retention and reduced tillage in an effort to control herbicide resistant weed populations. This research is aimed at conserving a novel mode of action herbicide with efficacy on resistant Lolium rigidum populations. The success of this project will inevitably lead the pesticide industry to adopt this approach for future product development. Read moreRead less
