Epidemiology of pathogens in wildlife populations: significance for conservation, human health and livestock. Recent research shows that pathogens may play a central role in wildlife population dynamics. Emergent disease problems in humans and livestock may result from reservoir infections in wildlife. However, methods to determine the impact of pathogens on populations, as distinct from individuals within populations, are poorly developed, as are models necessary to evaluate alternative control ....Epidemiology of pathogens in wildlife populations: significance for conservation, human health and livestock. Recent research shows that pathogens may play a central role in wildlife population dynamics. Emergent disease problems in humans and livestock may result from reservoir infections in wildlife. However, methods to determine the impact of pathogens on populations, as distinct from individuals within populations, are poorly developed, as are models necessary to evaluate alternative control strategies for pathogens, particularly where reservoir hosts are involved. This project will develop these methods using four case studies: chyridiomycosis in frogs, Hendra virus in bats, Newcastle disease in wild birds and arboviruses in kangaroos and other macropods.Read moreRead less
Phylogeography, evolution and taxonomy of humanity's greatest pest, Rattus rattus: Epidemiological, archaeological and conservation implications. This project will characterise a major threat to Australian biosecurity and health, and identify the range of likely disease risks associated with introductions of different 'strains' of black rat. It will provide critical data for management efforts around the world, especially for strategic partners in neighbouring Southeast Asian nations, as well as ....Phylogeography, evolution and taxonomy of humanity's greatest pest, Rattus rattus: Epidemiological, archaeological and conservation implications. This project will characterise a major threat to Australian biosecurity and health, and identify the range of likely disease risks associated with introductions of different 'strains' of black rat. It will provide critical data for management efforts around the world, especially for strategic partners in neighbouring Southeast Asian nations, as well as for conservation efforts within Australia. The data will also provide novel means to track the timing and routes of human prehistoric movements throughout the area. It will establish strategic research collaborations between researchers in zoological, medical, epidemiological, genetics, and conservation fields in a unique multi-disciplinary study.Read moreRead less
Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia ....Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia from invasive diseases. There is an urgency to undertake our research because global environmental change and increasing movements of people (particularly military personnel) from overseas regions where these diseases are endemic is increasing the vulnerability of northern Australia to the (re)establishment of mosquito borne diseases.Read moreRead less
Allocating scarce HIV/AIDS antiretroviral drugs in resource-constrained countries: using modelling to develop tools and analyse consequences of ethics and HIV-epidemiology. This project will benefit communities in some of the poorest countries of the world, suffering greatly from the HIV/AIDS epidemic. This research is important and timely for these nations in deciding how to distribute the limited treatment in an ethical manner to address treatment principles of these countries. However, the me ....Allocating scarce HIV/AIDS antiretroviral drugs in resource-constrained countries: using modelling to develop tools and analyse consequences of ethics and HIV-epidemiology. This project will benefit communities in some of the poorest countries of the world, suffering greatly from the HIV/AIDS epidemic. This research is important and timely for these nations in deciding how to distribute the limited treatment in an ethical manner to address treatment principles of these countries. However, the methods developed can also be applied to other diseases in different regions and people, such as Australian aborigines to increase their quality of health. Specifically, an epidemic of Chlamydia is widespread amongst the aboriginal communities of Australia's Northern Territory. Tools developed in this project will be easily adaptable to address control measures for Chlamydia among this population. Read moreRead less
Understanding spatial trends in HIV/AIDS infections in South Africa and Australia. 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 s ....Understanding spatial trends in HIV/AIDS infections in South Africa and Australia. 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
Evolutionary models and bioinformatic analyses of genetic variation in pathogens. The benefits of this project are better preparedness for the ever-present threat of infectious disease spread and the stimulation of bioinformatic research in Australia. Epidemics such as the Influenza Pandemic of 1918, which killed over 20 million people, highlight the need to understand and track pathogens that can potentially cause such devastation. Along with the development of molecular technologies, it is imp ....Evolutionary models and bioinformatic analyses of genetic variation in pathogens. The benefits of this project are better preparedness for the ever-present threat of infectious disease spread and the stimulation of bioinformatic research in Australia. Epidemics such as the Influenza Pandemic of 1918, which killed over 20 million people, highlight the need to understand and track pathogens that can potentially cause such devastation. Along with the development of molecular technologies, it is important to maintain active creation of analytical methods that appropriately apply to growing databases. These include methods to understand genetic variation in pathogens. This project will help to keep Australia at the forefront of research in theoretical biology.Read moreRead less
