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.

A Targeted Molecular Approach To Treating Scabies And Associated Bacterial Infections.
Funder
National Health and Medical Research Council
Funding Amount
$518,334.00
Summary
Chronic infestation of human skin with parasitic scabies mites is a severe health burden in Australian Indigenous communities and other disadvantaged communities around the world. Secondary infections with bacteria exacerbate this skin problem, with long-term, systemic and often fatal consequences including rheumatic heart disease. Analyses of the scabies mite genome and associated bacteria will accelerate biomedical research toward improved treatment and control of this neglected disease.
Targeting Toxoplasma Gondii Latent Stages Responsible For Chronic Disease
Funder
National Health and Medical Research Council
Funding Amount
$697,107.00
Summary
Many microbial pathogens become resistant to host immune response and drugs by entering a slow-growing, dormant state. These stages are commonly responsible for long term, chronic infections. We will investigate the molecular basis of dormancy in Toxoplasma gondii, which infects one in three people. These studies will identify metabolic pathways that are essential for dormancy with the view of developing new therapies for treating long term, recurrent infections.
INSIDE THE SKIN: UNDERSTANDING DIFFERENT HOST RESPONSES IN SCABIES
Funder
National Health and Medical Research Council
Funding Amount
$499,095.00
Summary
Scabies is an underlying cause of poor health in indigenous communities worldwide. Crusted scabies is a poorly understood, life-threatening form of the disease compromising the success of community control strategies. This research compares the immune response in the skin of scabies patients, and in a world-first animal model of human scabies. This will reveal specific immune defects predisposing to disease, ultimately resulting in improved skin health for disadvantaged communities
A New Animal Model For Genitourinary Schistosomiasis
Funder
National Health and Medical Research Council
Funding Amount
$395,711.00
Summary
Schistosoma haematobium causes genitourinary schistosomiasis, a serious disease that affects reproductive health, urinary system health and potentially bladder cancer. This species is the most pathogenic species of all schistosomes, but comparatively less is know about it than other species because of a lack of a suitable model. We need a suitable model host for this important parasite. This project will test whether newborn pigs can be used as laboratory models.
Metabolomic Analysis Of Plasmodum Falciparum And Mode Of Action Of Antimalarial Compounds
Funder
National Health and Medical Research Council
Funding Amount
$917,196.00
Summary
There is an urgent need to develop new drugs to treat malaria, one of the most important diseases to afflict humanity. We have developed new analytical approaches for measuring parasite metabolism while they live inside host cells. These approaches will be used to identify metabolic pathways that are essential for parasite infectivity and to understand the mode of action of new classes of antimalarial compounds
One third of the world's population is infected with the protozoan parasite, Toxoplasma gondii, which can cause life-threatening infections. This proposal will utilize new analytical technologies to understand how these parasites are able to survive in a wide variety of different host cells, how they manage to persist within brain and muscle tissue for the life of the patient and how infection may be linked to mental health disorders, such as schizopohrenia.
Scabies Mite Proteins As Targets For The Development Of New Therapeutics
Funder
National Health and Medical Research Council
Funding Amount
$299,564.00
Summary
Scabies and associated bacteria disease (pyoderma) are a significant health burden, with pyoderma implicated in rheumatic fever and heart disease. Investigations of the mechanism underlying scabies and bacteria disease links, identified scabies proteins inhibiting the human complement system. The inhibition prevents mite damage and promotes growth of bacteria. This proposal aims to elucidate the interaction between scabies, bacteria and the human host, in order to design new therapeutics.
Scabies Mite Intestinal Proteases As Targets For Novel Therapeutics.
Funder
National Health and Medical Research Council
Funding Amount
$672,533.00
Summary
Scabies causes bacterial disease affecting poor people worldwide. Available therapies are limited and drug resistance is emerging. We investigate molecules that the mite needs to infest the skin, to guide the formulation and the testing of novel drugs. This will provide improved treatment of affected individuals and their families, thereby reducing the spread of scabies and bacterial infections and their devastating sequelae, particularly in Australian Indigenous communities.
Genomic and molecular characterisation of a novel Australian leishmania pathogen. Leishmaniasis is the second most serious protozoal disease after malaria. This project will help characterise the first Leishmania species identified in Australia providing molecular tools to monitor the pathogen and a detailed assessment of any potential risk to human health. Comparative analysis with more pathogenic species will help identify genes and mechanisms that determine the progression of human disease le ....Genomic and molecular characterisation of a novel Australian leishmania pathogen. Leishmaniasis is the second most serious protozoal disease after malaria. This project will help characterise the first Leishmania species identified in Australia providing molecular tools to monitor the pathogen and a detailed assessment of any potential risk to human health. Comparative analysis with more pathogenic species will help identify genes and mechanisms that determine the progression of human disease leading to the potential identification of new drug and vaccine targets. The methodologies and expertise developed will be used will be available to other research groups working on infectious diseases.Read moreRead less
SBP1 And Altered Structure And Function Of Malaria-infected Red Blood Cells
Funder
National Health and Medical Research Council
Funding Amount
$439,550.00
Summary
Malaria is a serious disease affecting half the world's population. Every year, more than a million people (mostly children) die as a result of being infected with malaria parasites. Our work will help us to understand how the parasites alter normal human red blood cells and make them stick in organs such as the brain. Preventing the red blood cells from becoming sticky with new drugs will open up new lines of attack to combat this devastating disease.
