The central aim of this project is to increase the antigenicity of aroA mutant Salmonella Typhimurium vaccines, in particular Bioproperties’ Vaxsafe® ST. Increased antigenicity will affect the gut microbiota and stimulate a stronger host immune response improving vaccine efficacy and the duration of protection against S. Typhimurium in poultry. This will ultimately reduce bacterial loads in the farm environment, mitigate downstream contamination of the food supply chain, and reduce the number of human salmonellosis cases.Read moreRead less
A single vaccine for influenza and pneumonia. Influenza and bacterial pneumonia collaborate to kill millions of people each year. This project aims to develop a single vaccine that will provide long-lasting protection against both influenza and pneumonia.
A comparative study of the distribution and spread of potential molecular markers for Mundulla Yellows disease. Mundulla Yellows (MY), a newly recognised widespread lethal disease of Eucalyptus spp.in Australia, is a serious threat to national biodiversity and conservation. It is contagious, apparently biotic, but the causal agent is unknown. Identification of the cause is essential to establish sustainable control measures. We have detected a range of MY-associated RNAs constituting a disease ' ....A comparative study of the distribution and spread of potential molecular markers for Mundulla Yellows disease. Mundulla Yellows (MY), a newly recognised widespread lethal disease of Eucalyptus spp.in Australia, is a serious threat to national biodiversity and conservation. It is contagious, apparently biotic, but the causal agent is unknown. Identification of the cause is essential to establish sustainable control measures. We have detected a range of MY-associated RNAs constituting a disease 'fingerprint'. To identify individual RNAs uniquely associated with MY we aim to compare MY-RNA fingerprints from a range of affected species from different sites and with varying symptoms. Candidate RNAs will be cloned both for establishing molecular diagnostics for MY and identifying the cause.Read moreRead less
Quantitative Metagenomics. This project aims to revolutionize our view of the microbial world once more by transforming microbiome studies from relative counts of organisms to actual numbers of microbes. This project expects to impact all the microbiome studies that are being performed worldwide by unveiling the actual numbers of microbes. Expected outcomes of this project include new techniques to enumerate the number of bacteria in different environments and new approaches to measure gene expr ....Quantitative Metagenomics. This project aims to revolutionize our view of the microbial world once more by transforming microbiome studies from relative counts of organisms to actual numbers of microbes. This project expects to impact all the microbiome studies that are being performed worldwide by unveiling the actual numbers of microbes. Expected outcomes of this project include new techniques to enumerate the number of bacteria in different environments and new approaches to measure gene expression within individual bacteria in any environment that will be demonstrated with complex microbial communities. This should provide significant benefits because microbes affect every aspect of our lives and those effects are driven by how many microbes are present.Read moreRead less
Superbugs and veterinary drugs: are multidrug-resistant zoonotic pathogens residing in Australian animals? Antibiotic resistance is a growing problem affecting human health that is now emerging in animals and veterinary hospitals. This project will integrate surveillance with novel treatments and preventatives to develop effective strategies to limit the impact of resistant bacteria to animal health and prevent transfer between humans and animals.

This project aims to establish reference laboratories as biobanks for resistant isolate collections from veterinary diagnostic laboratories / surveillance programmes and a national research network to mitigate antimicrobial resistance in animals. Antimicrobial resistance in zoonotic/foodborne pathogens and livestock commensals is a global issue. This project will use mass-spectroscopy biotypers, information management software, robotic liquid handling and a research dairy to develop high-throughput screening technologies to rapidly determine major animal species’ resistance status, and research anti-infectives and vaccines for livestock diseases. This will improve the health and production of Australian livestock, leading to greater market access for high quality products.Read moreRead less
How to make antibiotics in pig feed redundant, naturally. Antimicrobial resistance has become a major issue in human and veterinary medicine being partially caused by the use of in-feed antimicrobials in farm animals. This project aims to completely eliminate antimicrobials from piglet feeds. The key differential approach is based on helping the physiology of the animal rather than testing interventions against bacteria. The project will consist of developing a novel nutritional strategy of natu ....How to make antibiotics in pig feed redundant, naturally. Antimicrobial resistance has become a major issue in human and veterinary medicine being partially caused by the use of in-feed antimicrobials in farm animals. This project aims to completely eliminate antimicrobials from piglet feeds. The key differential approach is based on helping the physiology of the animal rather than testing interventions against bacteria. The project will consist of developing a novel nutritional strategy of naturally (through maternal conditioning) boosting the natural appetite and the capacity to digest in piglets early in life. The anticipated outcome is that the new peri-natal program will result in minimal bacterial proliferation and diarrhoea thus, negating the need for in-feed antimicrobials in piglets.

Studying Molecular Dynamics with Electron and Laser Interactions. We plan to use state-of-the-art experimental techniques and methodologies to probe the dynamics of molecular processes stimulated by either laser or electron interactions. These processes are fundamental to our understanding of both natural phenomena and many devices used in the technology of today and of the future. As a result of this study our insight into the mechanisms underpining these phenomena and devices will be enhanced.

In conjunction with theoretical calculations, the results from these experiments will provide the most advanced evaluation for molecular orbital imaging quality for the chemically significant targets we wish to study. This in turn will lead to the determination of more accurate physico-chemical information, including structure and bonding information, for these targets.Read moreRead less
Cross sections for electron scattering from molecules and radicals of technological and environmental relevance. We will use two state of the art crossed beam spectrometers to measure absolute differential and integral cross sections for low energy electron scattering from molecules and their molecular fragments (radicals). The species to be considered are those of significant industrial (e.g. C2F4, C4F8 and CF2) and environmental (e.g. CO2 and H2O) interest, with the cross sections we will mea ....Cross sections for electron scattering from molecules and radicals of technological and environmental relevance.

The species to be considered are those of significant industrial (e.g. C2F4, C4F8 and CF2) and environmental (e.g. CO2 and H2O) interest, with the cross sections we will measure being crucial to our modelling both the processes involved in plasma enhanced chemical vapour desposition of semiconductor devices and the spectral emission characteristics of planetary atmospheres. The modelling will be conducted self-consistently with our enhanced statistical equilibrium simulation code, which is unique to Australia.Read moreRead less
