Summary
Tick-borne disease has emerged as a topical and controversial public health problem in Australia. We will employ state-of-the-art techniques in metagenomics to determine what microbial species (bacteria, viruses and eukaryotes) circulate in Australian ticks and whether these or different microbes are also present in humans diagnosed with tick-borne disease. The data generated will provide key information on whether tick-borne disease has a microbiological cause and, if so, the microbes involved.
Linking Genomics Of Burkholderia Pseudomallei To Melioidosis: Diversity Of Clinical Manifestations, Changing Epidemiology And Microevolution In Chronic Carriage.

Summary
The Darwin Prospective Melioidosis Study has documented 761 cases since 1989, with 102 fatalities. This study has led to improved therapy and public health initiatives. New technology to sequence whole bacterial genomes provides an opportunity to determine why urban melioidosis is increasing and to analyse this unique 22+ year set of bacteria and their linked patient data to find the important bacterial virulence factors, forming a foundation for future diagnostics, therapeutics, and vaccines.
Developing A New Treatment Method To Prevent Lymphopenia Associated With Sepsis

Summary
Sepsis or blood poisoning kills more people than breast cancer, prostate cancer and HIV/AIDS combined. It has a huge economic burden, yet there is no proper diagnostics markers or treatment. One of the main reasons for sepsis-mediated mortality is lack of functioning immune system patients. We have been able to elucidate the molecular mechanism of sepsis-mediated immune cell death and through this project, we aim to develop diagnostics and therapy for treating sepsis-mediated immune suppression.
Antibody-Dependent Cellular Cytotoxicity Based Immunity To Influenza

Summary
Pandemic influenza causes widespread disease, death and panic. Producing vaccines to new strains takes time. There is a need to produce vaccines that provide partial protection against unknown strains. We identified a type of anti-influenza antibody in people with prior influenza infection that may assist in reducing disease from new influenza strains. We will study these antibodies, understanding how effective they against influenza, with a view to making improved anti-influenza vaccines.
The Role Of Chemokine Networks In Severe Malaria And The Control Of Parasite Density

Summary
Two contributing factors have been identified as the main determinants of severe malaria: high parasite densities and host inflammatory responses. To date it is not clear whether inflammation is a cause or a consequence of high parasite densities. We have identified a new biomarker (IP-10) of disease severity in a malaria-endemic area of Papua New Guinea that is associated with high parasite densities. Here we will decipher the mechanisms by which IP-10 contributes to the development of high par ....Two contributing factors have been identified as the main determinants of severe malaria: high parasite densities and host inflammatory responses.

Secreted Exosome-like Vesicles From The Carcinogenic Liver Fluke

Funding Amount
$771,543.00
Summary
Parasitic liver flukes secrete microscopic cell-like vesicles into the bile ducts when feeding on infected humans. These vesicles, called exosomes, are taken up by the cells lining the bile ducts and promote them to become pre-cancerous. We will characterise the contents of these fluke exosomes and identify the key molecules on their surfaces that can be used to prevent exosome uptake by cells and ultimately form the basis of a vaccine that prevents fluke infection and subsequent liver cancer.
Malaria infection affects many millions around the world each year. This project brings together scientists working on mouse models of malaria and on clinical studies of malaria in Africa and Asia, with mathematicians and physicists who will analyse and model their experimental data. The project involves 'data mining' to apply novel statistical and mathematical modelling approaches to understand how the immune system controls malaria infection.
Genome-based Tools To Support Urogenital Schistosomiasis Control

Funding Amount
$429,644.00
Summary
More than 100 million sub-Saharan Africans have urogenital schistosomiasis, a disease that promotes malignant cancer and HIV/AIDS. Control depends on a single drug, making resistance an imminent threat. We will deliver new molecular tools to assess parasite genetic diversity and to prioritise a panel of anti-parasitic drug targets and vaccine candidates. These outcomes will deliver the next generation of interventions against urogenital schistosomiasis.

Summary
The single-celled parasite Toxoplasma gondii is the cause of Toxoplasmosis and is an important basis of eye disease, congenital birth defects and illness in immunocompromised individuals. To perpetuate infection T. gondii moves through tissue and invades host cells using a molecular motor, termed the 'glideosome'. We will reveal how the glideosome produces the force required for movement and characterise its critical features. Our work will provide a foundation in which to model novel drugs that ....The single-celled parasite Toxoplasma gondii is the cause of Toxoplasmosis and is an important basis of eye disease, congenital birth defects and illness in immunocompromised individuals.

Compounded by massive global food and water shortages, neglected tropical disease (NTD) pathogens have a devastating and long-term impact on billions of humans worldwide. Unlocking the fundamental molecular biology of these pathogens, particularly carcinogens, employing a raft of Frontier Technologies, will lead to new ways of controlling NTDs and will have substantial outcomes through the development of new drugs, vaccines and/or diagnostic tests.
