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.
Early Diagnosis And Prognosis Of Severe Dengue In Vietnamese Children

Summary
Dengue is a mosquito-borne viral infection. Tropical Australia has experienced multiple outbreaks of dengue in the last decade. This project, conducted in Ho Chi Minh City, Viet Nam, will define the accuracy of a rapid diagnostic test for the early diagnosis of severe dengue. In doing so, we will also derive an algorithm using simple laboratory and clinical findings that can help identify those patients at greatest risk of severe complications, with benefits for both patients and hospitals.
Immune Correlates Of Early Corticosteroid Therapy In Vietnamese Children And Young Adults With Dengue

Summary
Dengue is a globally important infectious disease. This study will seek to understand how corticosteroids, an immune modulating class of drug, effect the immune responses in children with dengue. The basis for this study is a randomised controlled trial at a large hospital in Viet Nam that treats many patients with dengue. We expect to obtain the laboratory evidence needed to support further clinical trials of this drug and in doing so we will improve our understanding of dengue.
Population Genomics Of Plasmodium Vivax In Papua New Guinea

Summary
Plasmodium vivax malaria is a serious global public health problem that has not received the attention it deserves, despite having serious clinical implications and presenting a major problem for regional malaria control programmes. In a study of people living in a malarious area of PNG, we aim to investigate the diversity of natural parasite populations, to better understand the possible effects of malaria control interventions on transmission and human immunity.
Schistosomiasis is a major public health problem in the Philippines with approximately 6.7 million people at risk of infection. Mass human chemotherapy has formed the cornerstone of control for decades but has failed to control the disease. Transmission reduction is a key step towards elimination and integrated interventions should target both definitive and intermediate host transmission pathways. We propose to trial integrated control strategies for the disease and expect the outcomes to have ....Schistosomiasis is a major public health problem in the Philippines with approximately 6.7 million people at risk of infection. Mass human chemotherapy has formed the cornerstone of control for decades but has failed to control the disease. Transmission reduction is a key step towards elimination and integrated interventions should target both definitive and intermediate host transmission pathways. We propose to trial integrated control strategies for the disease and expect the outcomes to have broader implications for Southeast Asia.Read moreRead less

Summary
Dengue, the commonest arboviral disease of humans, is caused by any of the four serotypes of dengue virus (DENV-1-4). This clinical research project will explore how acquired immunity to dengue viruses is expressed. The results will help dengue vaccine developers make better vaccines for use in Australian travellers and in dengue endemic countries in SE Asia.
The Darwin Prospective Melioidosis Study: Years 27-31

Summary
The Darwin Prospective Melioidosis Study has documented 914 cases since 1989, with 115 fatalities. A surge in Darwin melioidosis cases over the past 5 years has been linked to urban development and the discovery of a new bacterial strain. Whole genome sequencing of our unique 25+ year set of bacteria and their linked patient data will unravel the changing epidemiology and identify important virulence factors, forming a foundation for future diagnostics, therapeutics, and vaccines.
How The Environment And Epigenetics Affect The Brain Disease Gene, MAPT.

Summary
Genetic variants in the microtubule associated protein Tau (MAPT) gene are major risk factors for Alzheimer’s disease and Parkinson’s disease. Environmental or lifestyle factors, such as diet and smoking, have crucial roles in changing the risk of developing these diseases. These environmental factors may exert their influence via a mechanism known as "epigenetics". This project aims to determine whether the MAPT gene is susceptible to epigenetic changes by environmental factors, and whether thi ....Genetic variants in the microtubule associated protein Tau (MAPT) gene are major risk factors for Alzheimer’s disease and Parkinson’s disease. Environmental or lifestyle factors, such as diet and smoking, have crucial roles in changing the risk of developing these diseases. These environmental factors may exert their influence via a mechanism known as "epigenetics". This project aims to determine whether the MAPT gene is susceptible to epigenetic changes by environmental factors, and whether this process will have an impact on these diseases.Read moreRead less

Summary
Truncations of the PRESENILIN genes in humans can cause two very different diseases: inherited, early onset Alzheimer’s disease (familial Alzheimer's disease) and a skin disease named inherited Acne Inversa. One truncation is also involved in the non-inherited, late onset form of Alzheimer’s disease. Why do these different truncations produce different diseases? Investigating this question will teach us more about the molecular bases of these different diseases.

Summary
ParkinsonÍs disease (PD) is an incurable, brain disease that affects 75,000 Australians with great societal cost. We are working on adult stem cells called (hONS) grown from peopleÍs olfactory mucosa (in the nose) as a research tool to study PD. Our project examines differences seen in hONS from people with PD and determines how certain cellular processes impact on the function of these cells. This work will enhance our understanding of the biology of PD and identify new targets for therapies.
