Using molecular tools to understand and control the transmission of Cryptosporidium. Cryptosporidium is the major public health concern of water utilities as the parasite has a global impact on the health and survival of millions of people and animals worldwide. It is resistant to chlorine and there are no effective drugs against it. Control strategies therefore rely on understanding how it is transmitted. This project will conduct a comprehensive study utilising molecular tools to determine if ....Using molecular tools to understand and control the transmission of Cryptosporidium. Cryptosporidium is the major public health concern of water utilities as the parasite has a global impact on the health and survival of millions of people and animals worldwide. It is resistant to chlorine and there are no effective drugs against it. Control strategies therefore rely on understanding how it is transmitted. This project will conduct a comprehensive study utilising molecular tools to determine if the Cryptosporidium in humans is the same as that derived from water contamination sources (animals, sewage etc). The outcomes of this project will result in the development of more targeted, cost-effective preventive measures to minimize exposures to infections, accurate risk assessment, and scientific management of the watershed.Read moreRead less

This project will develop quantitative methods that will be used to inform public health officials in understanding past and current HIV/AIDS epidemics as well as planning for the future of these epidemics. It will understand not only the behavioural and demographic characteristics of importance as risk factors for HIV infection in South Africa, the epicentre of the global HIV pandemic, but also the geographical spatial locations in which HIV cases are likely to emerge in the future. This project will also forecast the future geographical trends in Australia's changing HIV epidemic in order to plan for intervention strategies and prepare clinical practice appropriately.Read moreRead less
The multiplexed diagnosis of arbovirus infections using combinatorial probes. Viruses that cause serious diseases such as hemorrhagic fever or encephalitis must be quickly identified. Diagnostic tests based on DNA hybridisation are accurate and can be rapid but they are expensive. We will test a method for simplifying DNA tests and increasing their capabilities. DNA probes for detecting arboviruses will be designed at the ANU using new bioinformatic methods and their reliability will be model ....The multiplexed diagnosis of arbovirus infections using combinatorial probes. Viruses that cause serious diseases such as hemorrhagic fever or encephalitis must be quickly identified. Diagnostic tests based on DNA hybridisation are accurate and can be rapid but they are expensive. We will test a method for simplifying DNA tests and increasing their capabilities. DNA probes for detecting arboviruses will be designed at the ANU using new bioinformatic methods and their reliability will be modelled using all the available genetic information. Computer predictions will be experimentally tested in the PANBIO laboratory by using the probes to detect viral nucleic acids. The influence of virus genome complexity will be investigatedRead moreRead less
Modelling disease evolution and emergence. Approximately 75% of all emergent diseases have established in humans having switched from other species: Human Immunodeficiency Virus (HIV), Malaria, SARS (Severe Acute Respiratory Syndrome), Ebola, West Nile Virus and many more. Further, cross species infections put our biodiversity and economy at risk: plant and animal diseases entering Australia can destroy crops and at-risk native species. This project will provide for the first time the statistica ....Modelling disease evolution and emergence.

Environmental influence on evolutionary processes in bacterial populations. Bacterial populations exhibit remarkable adaptive capabilities in many environmental and medical settings. They respond to environmental stress in terms of altered gene expression, but what are the effects on mutation rates and fitness when cells grow at suboptimal growth rates? We plan to test whether the physiological state of an ancestral population is a determinant of a population's subsequent response to selection. ....Environmental influence on evolutionary processes in bacterial populations. Bacterial populations exhibit remarkable adaptive capabilities in many environmental and medical settings. They respond to environmental stress in terms of altered gene expression, but what are the effects on mutation rates and fitness when cells grow at suboptimal growth rates? We plan to test whether the physiological state of an ancestral population is a determinant of a population's subsequent response to selection. A simple model system using controlled culture conditions will be used to investigate the linkage between environment, mutation rate and fitness under selection. Demonstration of these linkages will have significant impacts on microbiology and understanding evolution.Read moreRead less
Who acquires infection from whom across international borders? New approaches for control of emerging infections through understanding travel patterns.

New approaches for control of emerging infections through understanding travel patterns. Mathematical modelling of data on travellers traversing Australia's borders and their contact patterns can be used to understand the pathways by which infectious diseases enter and spread in Australia. Currently available social contact data which informs models are inadequate and outdated. Gathering new data relevant to modern society will help control future infectious disease threats to our society. Our aim is to collect detailed, unique data on demography, behavioural and social patterns of travellers and residents, and use this to develop mathematical models to evaluate effective control measures for emerging infections in Australia. This study will make a unique contribution to national disease control policy.Read moreRead less
