The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Arbovirus Activation And Modulation Of NLRP3 Inflammasome
Funder
National Health and Medical Research Council
Funding Amount
$779,720.00
Summary
This project aims to establish how mosquito borne viruses such as Ross River and dengue viruses interacts with the human host to cause disease, including how the virus evades the host’s immune response to persist and cause disease for prolonged periods. Knowing how differences in the virus and the host’s immune system interplay to cause asymptomatic to severely disabling disease will assist in devising new treatments and prevention programs to lessen the impact of these diseases in Australia.
New Insights Into Viral Inflammatory Disease Mechanisms And Approaches To Therapy

Summary
This fellowship aims to establish how viruses cause disease, including how they evade the immune response to persist and cause disease for prolonged periods. My vision is that knowing how the virus and the immune system interact to determine disease severity will assist in devising new treatments and prevention programs to lessen the impact of viral diseases in Australia and worldwide.
Mosquito-borne alphaviruses such as Ross River and chikungunya viruses cause widespread epidemics and exert extreme pressure on the public health systems of affected regions. Alphaviruses spreads to joints and triggers a severe disease in those affected. There are no effective treatments or vaccines. The project will investigate virus-host interaction at the bite site. The outcome will be new knowledge to treat infection at the mosquito bite site to prevent joint disease.
Novel Insights Into The Pathobiology Of Alphavirus Infections

Funding Amount
$827,660.00
Summary
Infections with mosquito-borne viruses are increasing at an alarming rate worldwide. Ross River virus is endemic in parts of Australia, PNG and Pacific islands, while chikungunya virus is distributed globally and causes recurrent pandemics that involve millions of people. These viruses cause severe musculoskeletal disease for several months after infection. This project aims to establish how these viruses interact with the human host to cause disease and may provide a basis for new treatments.
Glycotherapeutics; A New Class Of Treatment For Alphavirus-induced Musculoskeletal Disease
Funder
National Health and Medical Research Council
Funding Amount
$449,868.00
Summary
The hallmark of alphavirus disease is crippling pain and joint arthritis, which often has an extended duration. Currently there is no licenced specific treatment for alphavirus disease and the increasing spread of infection highlights an urgent need for therapeutic intervention strategies. This grant looks at the potential of pentosan polysulfate as a promising drug-repurposing candidate for the treatment of alphavirus-induced arthritis.
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
Understanding the molecular basis of virulence in Brachyspira hyodysenteriae to improve vaccine design. 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 vac ....Understanding the molecular basis of virulence in Brachyspira hyodysenteriae to improve vaccine design. 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
Genomic sequencing and comparative genomic analysis for animal bacterial vaccine discovery. The aim of this project is to develop vaccines for the control of swine dysentery (pigs) and intestinal spirochaetosis (pigs and chickens). These infections cause important production-limiting diseases for which no effective vaccines are available. We will use whole genomic sequencing of the two causal species of intestinal spirochaetal bacteria, with a bioinformatics-based analysis of the data to identif ....Genomic sequencing and comparative genomic analysis for animal bacterial vaccine discovery. The aim of this project is to develop vaccines for the control of swine dysentery (pigs) and intestinal spirochaetosis (pigs and chickens). These infections cause important production-limiting diseases for which no effective vaccines are available. We will use whole genomic sequencing of the two causal species of intestinal spirochaetal bacteria, with a bioinformatics-based analysis of the data to identify potential cell surface structures that will be tested as the basis of new recombinant vaccines. Outcomes will include the development of new commercial products, increased institutional capacity in veterinary vaccine discovery, and ultimately improved animal health and production in rural Australia.Read moreRead less
Harnessing the genome of the Australian paralysis tick to develop effective control products. This project aims to examine the potent cocktail produced by the salivary gland of Australia's paralysis tick. The paralysis tick continues to cause severe illness and deaths for companion pets with up to 100,000 cases of toxicoses per year. This project aims to develop new safe treatments and/or preventative vaccines.

This targeted approach will raise Australia's standing in the field, assist in the community's understanding of parasitology and biosecurity and maintain and improve Australia's capacity for keeping its stock, crops, wildlife and people disease-free. On an international scale, the Network will work with other countries to develop new technologies for the detection and eradication of parasites. This emphasis will not only protect Australia's borders but will assist our near neighbours and lead to the development of technologies with an economic benefit to Australia.
