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 Targeted Molecular Approach To Treating Scabies And Associated Bacterial Infections.

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.
A New Animal Model For Genitourinary Schistosomiasis

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.
Novel Serological Tools To Aid Malaria Elimination In The Asia-Pacific

Summary
In 2014 Asia-Pacific leaders pledged a malaria free Asia-Pacific by 2030. We will contribute to this goal by developing novel antibody detection tests that can identify people with current and recent past infections. We will then evaluate the utility of these tests both in mass screening and treatment programs and for the rapid delineation of areas where transmission persists from those where it has been eliminated. This will address two major roadblocks to malaria elimination in our region.
Scabies Mite Proteins As Targets For The Development Of New Therapeutics

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.

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.
Helminth Secreted Proteins – From Anthelmintic Vaccines To Therapies For Autoimmunity

Funding Amount

Summary
Human helminths (worms) cause chronic disease in developing countries, yet their disappearance from developed countries has been accompanied by an increase in the prevalence of autoimmune and allergic diseases. My resesarch focuses on the proteins these worms secrete and their use in (1) the development of anthelmintic vaccines, and (2) the development of novel anti-inflammatory molecules to treat autoimmunity, particularly diseases affecting the gut.
Apical Membrane Proteins As Targets For A Schistosomiasis Vaccine

Funding Amount

Summary
Schsitosomiasis is a chronic neglected tropical disease for which there is currently no vaccine. A vaccine is sorely needed to control this parasite. This proposal seeks to identify molecules from the outer surface of the parasite which are recognised by the immune system of people from Brazil who are resistant to schistosomiasis. Molecules identified in this manner will be tested as vaccines in an animal model of schistosomiasis, and ranked based on their performances to enter human trials.
MOLECULAR APPROACHES TO OVERCOME SCABIES AND ASSOCIATED DISEASE. Scabies causes childhood pyoderma predisposing to severe disease in later life. It is a major increasing health burden in Indigenous people of Northern Australia. Drug resistance is developing in mites and bacteria. The lack of clinical material has hampered molecular research and this work will use comparative genomics of parasitic and free living mites and microbiome analysis to understand fundamental aspects of mite biology and ....MOLECULAR APPROACHES TO OVERCOME SCABIES AND ASSOCIATED DISEASE. Scabies causes childhood pyoderma predisposing to severe disease in later life. It is a major increasing health burden in Indigenous people of Northern Australia. Drug resistance is developing in mites and bacteria. The lack of clinical material has hampered molecular research and this work will use comparative genomics of parasitic and free living mites and microbiome analysis to understand fundamental aspects of mite biology and pathogenesis. The understanding of proteins that are essential for mite survival and interfere with host defences will allow the informed design of peptide inhibitors as a new strategy to develop alternative treatment options.Read moreRead less
Molecular dissection of malaria parasite motility and host-cell invasion across the lifecycle. Malaria parasites move in a unique way, gliding across cell surfaces and infecting host cells using a unique molecular motor. This research aims to understand the molecular mechanics behind parasite movement and use this to develop novel drugs that might throw a spanner in the parasite motor, blocking movement and thereby preventing malaria disease.
