Molecular approaches to solving current and emerging problems in the epidemiology and diagnosis of Marek's disease in Australia. Marek's disease (MD) is a ubiquitous viral disease of chickens that is currently controlled in meat chickens by blanket vaccination of all chickens. However, as has happened overseas, the efficacy of the HVT vaccine being used in Australia is breaking down resulting in subclinical and clinical losses due to MD. To assist industry deal with this situation we propose to ....Molecular approaches to solving current and emerging problems in the epidemiology and diagnosis of Marek's disease in Australia. Marek's disease (MD) is a ubiquitous viral disease of chickens that is currently controlled in meat chickens by blanket vaccination of all chickens. However, as has happened overseas, the efficacy of the HVT vaccine being used in Australia is breaking down resulting in subclinical and clinical losses due to MD. To assist industry deal with this situation we propose to develop novel molecular methods for the quantification of Marek's disease viruses (MDV) in the host and the environment, to use these methods to design effective early monitoring systems for MD in broilers that predict disease and performance outcomes, and to develop an epidemiological model that will predict the spread and severity of MD as failure of vaccinal protection progresses.Read moreRead less
Reduction of antibiotic usage in the commercial pig industry. This project intends to identify factors that make a pig enterprise more likely to use high levels of antibiotics and develop alternative, vaccination-based methods for disease control. The development of multi-drug resistance in zoonotic bacterial pathogens (e.g. Salmonella and Campylobacter spp.) in pigs has raised concerns that antimicrobial resistance can be transferred from livestock to humans. Although the epidemiology to suppor ....Reduction of antibiotic usage in the commercial pig industry. This project intends to identify factors that make a pig enterprise more likely to use high levels of antibiotics and develop alternative, vaccination-based methods for disease control. The development of multi-drug resistance in zoonotic bacterial pathogens (e.g. Salmonella and Campylobacter spp.) in pigs has raised concerns that antimicrobial resistance can be transferred from livestock to humans. Although the epidemiology to support a claim that there is a causal association between antimicrobial use in food animals and public health is complex there is universal agreement that use of antimicrobials in food animal production should be minimised. This project intends to deliver outcomes that will reduce antibiotic use on commercial pig farms.Read moreRead less
Reducing antibiotic usage in pig herds: controlling Lawsonia intracellularis by vaccination, housing and hygiene. Pigs are major consumers of antibiotics in Australia. Many of these antibiotics are fed to pigs to prevent proliferative enteritis (PE). There are increasing public concerns regarding the development and spread of antibiotic-resistant bacteria and the potential impact on human health. The adoption of an effective commercial vaccine to prevent PE will reduce the volume of antibiotics ....Reducing antibiotic usage in pig herds: controlling Lawsonia intracellularis by vaccination, housing and hygiene.

There are increasing public concerns regarding the development and spread of antibiotic-resistant bacteria and the potential impact on human health. The adoption of an effective commercial vaccine to prevent PE will reduce the volume of antibiotics used in the pig industry and hence reduce the risk of antibiotic-resistant bacteria developing.Read moreRead less

Summary
Socioeconomic effects of fault attribution after a motor vehicle crash. This project aims to identify claimant and crash risk characteristics that predict elevated socio-economic burden on injured persons, compensation systems and the public health system. 19% of Australians injured in road trauma annually report long-term reductions in social participation and work capacity, and have costly health service needs. Attributions of fault lead to perceived injustice and affect the capacity to cope w ....Socioeconomic effects of fault attribution after a motor vehicle crash. This project aims to identify claimant and crash risk characteristics that predict elevated socio-economic burden on injured persons, compensation systems and the public health system. 19% of Australians injured in road trauma annually report long-term reductions in social participation and work capacity, and have costly health service needs. Attributions of fault lead to perceived injustice and affect the capacity to cope with trauma. This project will evaluate the effect of fault attributions on socioeconomic outcomes. Expected results include approaches for identifying those at greatest risk of poor outcomes who need additional support after a crash.Read moreRead less
Discovery of Novel Respiratory Viruses Causing Influenza-Like Illness in Healthy Australian Adults Aged 18 to 64 Years. This work will inform our understanding of the causes of acute respiratory illnesses in Australia at the present time by looking for both known and previously undiscovered respiratory viruses. Increasing the knowledge base regarding causes of disease will have downstream relevance for health policy planners seeking to assess the burden of disease due to different causes.

This work will inform our understanding of the causes of acute respiratory illnesses in Australia at the present time by looking for both known and previously undiscovered respiratory viruses. Increasing the knowledge base regarding causes of disease will have downstream relevance for health policy planners seeking to assess the burden of disease due to different causes. Early identification and description of new diseases will allow pre-emptive evaluation of new public health threats. This information will help to ensure availability and marketability of vaccines to prevent infection.Read moreRead less

Network modelling nationally important emerging infectious diseases. The project aims to develop decision-support tools for emerging infectious disease outbreaks that build on recent advances in gene sequencing and predictive modelling. Infectious disease transmission depends on the proximity and attributes of infectious and susceptible animals, evolution of the host-pathogen relationship and environmental influences. Recent changes in these have led to a series of major outbreaks with impacts o ....Network modelling nationally important emerging infectious diseases. The project aims to develop decision-support tools for emerging infectious disease outbreaks that build on recent advances in gene sequencing and predictive modelling. Infectious disease transmission depends on the proximity and attributes of infectious and susceptible animals, evolution of the host-pathogen relationship and environmental influences. Recent changes in these have led to a series of major outbreaks with impacts on animal health, productivity and trade. New decision-support tools are required to combine genetic sequences with epidemiological data early in large outbreaks. The intended outcome of the project is that the models developed may enable appropriate and timely intervention and reduce impacts in future outbreaks.Read moreRead less

These data are urgently needed, not just in Australia, but globally to inform pandemic planning and disease control policy around emerging infections and bioterrorism.Read moreRead less
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
Attrition in longitudinal studies: advancing and evaluating statistical methods. Longitudinal studies are a vital tool for monitoring the health and well-being of Australians. They are uniquely placed to examine changes in diseases over time and prospectively collect data on exposure and disease onset.

They are uniquely placed to examine changes in diseases over time and prospectively collect data on exposure and disease onset. There have been many successful longitudinal studies in Australia that have lead to significant breakthroughs in evidence-based health (e.g. the Nambour Skin Cancer Prevention Trial). Unfortunately all longitudinal studies suffer from attrition, or loss of participants, which leads to questions concerning their validity and generalisability. This project will investigate the causes of attrition, and the effect attrition has on longitudinal studies, in order to improve their design and analysis.Read moreRead less
