Designing new generation adjuvants for allergy and parasite vaccines. Allergy vaccines have the potential to provide a permanent cure against many allergic diseases, currently affecting 20-30 per cent of people in developed countries. This project will study how allergy vaccines work and how we can improve their effectiveness and safety.
Evaluating host-parasite interplay in individual tissues. The immune system of the host and the infecting parasite has coevolved into a sophisticated balance of power. This project will explore this balance using Schistosoma japonicum infection in sheep and determine immune mechanisms unleashed by the host in various tissues as well as the response of the parasite to these attacks.
Deciphering the molecular mechanisms of parasite-host interactions. The completion of genome projects for several helminths of veterinary significance has provided novel insights into the fundamentals of helminth biology. One outcome is the identification of microRNAs, a subclass of small regulatory RNAs which in plants and mammalian cells control diverse biological processes at the posttranscriptional level. We have discovered the presence of helminth miRNAs within host cells with the ability t ....Deciphering the molecular mechanisms of parasite-host interactions. The completion of genome projects for several helminths of veterinary significance has provided novel insights into the fundamentals of helminth biology. One outcome is the identification of microRNAs, a subclass of small regulatory RNAs which in plants and mammalian cells control diverse biological processes at the posttranscriptional level. We have discovered the presence of helminth miRNAs within host cells with the ability to mimic mammalian miRNAs to modulate innate immune responses. This project will discover how helminths hijack the mammalian miRNA machinery to regulate host gene expression and thus support long-term infection. The outcomes will highlight new avenues for the control of these persistent worm infections.Read moreRead less

Summary
Transmission dynamics modelling of zoonotic neglected tropical diseases. This project will develop mathematical models to simulate zoonotic disease transmission and control. Results will provide novel insight for policy makers into effective interventions for schistosomiasis, echinococcosis and clonorchiasis, as well as provide a methodological platform for adaptation to other zoonotic emerging and re-emerging diseases.
Optimisation of a novel hybrid vaccine for liver fluke disease in cattle. Optimisation of a novel hybrid vaccine for liver fluke disease in cattle. This project aims to optimise the formulation of novel fluke vaccine antigens by constructing combination hybrid recombinant antigens and using a protein adjuvant to improve immunogenicity, and test new antigens expressed in young flukes as vaccines and evaluate their ability to synergise with hybrid vaccines. Fasciola (fluke) infections cause seriou ....Optimisation of a novel hybrid vaccine for liver fluke disease in cattle. Optimisation of a novel hybrid vaccine for liver fluke disease in cattle. This project aims to optimise the formulation of novel fluke vaccine antigens by constructing combination hybrid recombinant antigens and using a protein adjuvant to improve immunogenicity, and test new antigens expressed in young flukes as vaccines and evaluate their ability to synergise with hybrid vaccines. Fasciola (fluke) infections cause serious economic losses to livestock production and fluke drug resistance threatens control, so new therapies such as a vaccine are needed. These vaccines should be evaluated in cattle trials. The major outcome plan is validation of hybrid antigens for commercial vaccine development for fluke control in cattle, leading to more sustainable beef and milk production in Australia.Read moreRead less
Harnessing the genome of the Australian paralysis tick to develop effective control products. This project aims to examine the potent cocktail produced by the salivary gland of Australia's paralysis tick. The paralysis tick continues to cause severe illness and deaths for companion pets with up to 100,000 cases of toxicoses per year. This project aims to develop new safe treatments and/or preventative vaccines.
Targeted drug discovery against blood-feeding parasite nematodes of animals. This project aims to identify more sustainable control strategies of nematode parasites of livestock, which cost more than 400 million yearly to the Australian wool and meat industry. The project expects to identify novel nematicides and generate knowledge of the parasite biology using a combination of high-throughput drug discovery screens with cutting-edge OMICs approaches to target a key molecular pathway of importan ....Targeted drug discovery against blood-feeding parasite nematodes of animals. This project aims to identify more sustainable control strategies of nematode parasites of livestock, which cost more than 400 million yearly to the Australian wool and meat industry. The project expects to identify novel nematicides and generate knowledge of the parasite biology using a combination of high-throughput drug discovery screens with cutting-edge OMICs approaches to target a key molecular pathway of importance to the survival of nematodes, namely their blood-feeding behaviour. Expected outcomes of this project include a likely enhancement of international efforts in controlling these parasites as well as nematicides commercialisation. This should provide significant benefits to agricultural producers in Australia and worldwide.

Troublesome ticks: a new molecular toolkit to investigate zoonotic tick-borne pathogens in Australia. This project will use the latest molecular diagnostic techniques to address unanswered questions about potential tick-transmitted diseases of humans and companion animals in Australia. The study will identify 'hot-spots' for tick-borne pathogens, identify areas of potential risk for humans, and investigate vector-host-pathogen interactions nationwide.
Ecology and transmission of tick-borne disease in Australia. Ecology and transmission of tick-borne disease in Australia. This project aims to determine the bacterial, protozoal and viral biodiversity in wildlife ticks and their native mammal hosts, and provide new information about the biology and transmission dynamics of these microorganisms and their potential to cause disease in wildlife, domesticated animals and humans.

Chemo-prevention of tropical canine parasitoses and vector-borne diseases. This project will determine the prevalence and diversity of established, emerging and novel canine vector-borne agents and endoparasites in a tropical setting by using conventional and next generation molecular diagnostic tools. It will fill an important gap by providing independently-verified evidence on how well canine anti-parasitic products marketed in Australia and Asia by Bayer Animal Health, perform in high-infecti ....Chemo-prevention of tropical canine parasitoses and vector-borne diseases. This project will determine the prevalence and diversity of established, emerging and novel canine vector-borne agents and endoparasites in a tropical setting by using conventional and next generation molecular diagnostic tools. It will fill an important gap by providing independently-verified evidence on how well canine anti-parasitic products marketed in Australia and Asia by Bayer Animal Health, perform in high-infection pressure settings, as a chemo-preventative for these disease agents. Tropical regions spanning northern Australia and Southern Asia are highly conducive to a plethora of canine vector-borne and parasitic pathogens that cause significant morbidity and mortality in dogs. Many of these agents also pose a risk to public health. The outcomes will be directly translated to best-practice guidelines for the advancement of companion animal (and indirectly human) health and welfare.Read moreRead less
